A9579Gadolinium-based contrast dye injection for MRI scan (1 ml)
This code represents one milliliter of a gadolinium-based contrast agent that is injected into your body during an MRI (magnetic resonance imaging) scan. Gadolinium is a safe contrast material that helps make certain body parts, blood vessels, or abnormal tissues show up more clearly on MRI images. The 'not otherwise specified' means this covers gadolinium contrast agents that don't fall into other specific categories. The contrast dye is typically given through an IV line in your arm before or during the MRI procedure.
G8950Documentation of elevated or high blood pressure with follow-up plan recorded
This code is used when a healthcare provider has documented that a patient had an elevated or high blood pressure reading during a visit, and the provider has also documented what follow-up care or monitoring is recommended. This ensures that both the blood pressure concern and the plan for addressing it are properly recorded in the medical record.
G0476HPV DNA test for high-risk cancer-causing types (combined with Pap test)
This is a laboratory test that looks for the genetic material (DNA or RNA) of high-risk human papillomavirus (HPV) types that can cause cervical cancer. The test specifically checks for HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68. This test must be done together with a Pap test as part of cervical cancer screening. The combination of both tests provides more comprehensive screening than either test alone.
G0145Automated cervical or vaginal cancer screening test with thin-layer preparation and manual review
This is a cervical or vaginal cancer screening test (like a Pap smear) where cells are collected and preserved in a special fluid. The sample is prepared using an automated thin-layer technique, then screened by an automated computer system. After the automated screening, a trained technician manually reviews the results under physician supervision to ensure accuracy. This type of screening helps detect abnormal cells that could indicate cervical or vaginal cancer or pre-cancerous conditions.
G8754Documentation that your most recent diastolic blood pressure reading was less than 90 mmHg
This code is used to document that your most recent diastolic blood pressure (the bottom number in a blood pressure reading) was measured at less than 90 mmHg. The diastolic pressure represents the pressure in your arteries when your heart is resting between beats. A diastolic reading below 90 mmHg is generally considered within normal to optimal range for blood pressure control.
G8752Documentation that your most recent systolic blood pressure reading was less than 140 mmHg
This code is used to document that your most recent systolic blood pressure measurement was below 140 mmHg. Systolic blood pressure is the top number in a blood pressure reading and represents the pressure in your arteries when your heart beats. A reading below 140 mmHg for the systolic pressure is generally considered within acceptable ranges for blood pressure control.
G8420Documentation that BMI (Body Mass Index) is within normal range with no follow-up needed
This code indicates that your Body Mass Index (BMI) has been calculated and documented as being within normal, healthy parameters. BMI is a measurement that uses your height and weight to assess if you're in a healthy weight range. Since your BMI is normal, your healthcare provider has determined that no additional follow-up plan or intervention is required at this time.
G0382Level 3 emergency department visit at a Type B emergency department
This code represents a moderate complexity emergency department visit (Level 3) that takes place in a Type B emergency department. A Type B emergency department is a facility that meets specific requirements: it must be either licensed by the state as an emergency room/department, publicly advertised as providing urgent emergency care without appointments, or provide at least one-third of its outpatient visits for emergency conditions without requiring scheduled appointments. Level 3 visits typically involve moderately complex medical decision-making and evaluation of patients with urgent but not immediately life-threatening conditions.
G0101Cancer screening exam including pelvic exam and clinical breast exam
This code represents a preventive care visit that includes screening for cervical or vaginal cancer through a pelvic examination, combined with a clinical breast examination performed by a healthcare provider. During the pelvic exam, the doctor examines the reproductive organs to check for signs of cancer or other abnormalities. The clinical breast exam involves the healthcare provider physically examining the breasts and surrounding areas to feel for lumps or other changes that might indicate cancer.
J7613Albuterol breathing medication, non-compounded, 1 mg unit dose
This code represents a 1 mg unit dose of albuterol inhalation solution that is FDA-approved and non-compounded (not custom-mixed). Albuterol is a bronchodilator medication that helps open airways in the lungs, making it easier to breathe. This specific form is administered through durable medical equipment (DME) such as a nebulizer machine. Each unit dose contains 1 mg of albuterol in a pre-measured solution ready for inhalation treatment.
G0333Pharmacy dispensing fee for inhaled medications (first 30-day supply)
This code represents the fee charged by a pharmacy for dispensing inhaled medications for the initial 30-day supply. This is specifically the service fee for preparing and providing the medication, separate from the cost of the medication itself. It applies to medications that are inhaled, such as those used for asthma, COPD, or other respiratory conditions.
Q0091Collection and preparation of a Pap smear for cervical cancer screening
This code covers the healthcare provider's work to collect a sample of cells from your cervix or vagina using a small brush or spatula during a pelvic exam. The provider then prepares this sample and sends it to a laboratory for analysis to screen for cervical cancer and precancerous changes. This is the collection and handling portion of a Pap smear test, which is separate from the actual laboratory analysis of the sample.
G8427Documentation that your doctor reviewed your current medications
This code indicates that an eligible healthcare provider has documented in your medical record that they obtained, updated, or reviewed your current list of medications. This is an important safety measure to ensure your doctor has accurate, up-to-date information about all the medications you are taking, including prescription drugs, over-the-counter medications, and supplements.
G8510Documentation that depression screening was negative and no follow-up plan is needed
This code is used by healthcare providers to document that a patient was screened for depression and the results were negative (meaning no signs of depression were found). Because the screening was negative, no follow-up treatment plan or additional monitoring for depression is required at this time. This is a documentation code that helps track that proper depression screening was performed and the results.
G02793D mammography imaging (breast tomosynthesis)
This code represents diagnostic digital breast tomosynthesis, which is a specialized type of 3D mammography. It creates detailed, layered images of breast tissue that can be viewed slice by slice, similar to a CT scan but specifically for breast imaging. This procedure can be performed on one breast (unilateral) or both breasts (bilateral) and is used in addition to standard mammography to get clearer, more detailed images of breast tissue. The 3D imaging helps radiologists see through overlapping tissue layers that might obscure abnormalities in traditional 2D mammograms.
G0442Annual alcohol screening appointment (5-15 minutes)
This code represents an annual screening appointment to assess alcohol use patterns and identify potential alcohol misuse. The screening typically involves questions about drinking habits and takes between 5 to 15 minutes to complete. This is a preventive health service designed to identify alcohol-related concerns early and provide appropriate guidance or referrals if needed.
Q5001Hospice or home health care services provided in your home or residence
This code represents hospice care or home health services that are delivered directly in your home or place of residence. This allows you to receive professional medical care, comfort care, or end-of-life services in the familiar environment of your own home rather than in a hospital or facility setting.
J0696Ceftriaxone sodium antibiotic injection, billed per 250 mg dose
This code represents billing for ceftriaxone sodium, a powerful antibiotic medication given by injection (either into a vein or muscle). The code covers each 250 mg portion of the medication administered. Ceftriaxone is a broad-spectrum antibiotic used to treat various bacterial infections. This is specifically the billing code for the medication itself, not the administration procedure.
G8783Documentation of normal blood pressure reading with no follow-up needed
This code is used when a healthcare provider documents that a patient's blood pressure reading was normal and within healthy ranges, and therefore no additional follow-up appointments or monitoring are required at this time. This represents a positive health outcome where the blood pressure screening showed results that don't require further medical attention or intervention.
A9270Non-covered item or service
This code indicates that a particular medical item or service is not covered by your insurance plan or Medicare/Medicaid. When this code appears on your medical bill or claim, it means the insurance company has determined that the specific treatment, procedure, equipment, or service does not qualify for coverage under your current benefits. You may be responsible for paying the full cost of this item or service out-of-pocket.
A7034Nasal mask or tube device for sleep apnea machines
This is a nasal interface device that connects to a positive airway pressure (PAP) machine, commonly used for treating sleep apnea. It can be either a nasal mask that covers the nose or nasal cannula (small tubes that go in the nostrils). The device may include a head strap to keep it in place during sleep. This interface allows the PAP machine to deliver pressurized air through your nose to keep your airway open while you sleep.
G0180Doctor's certification for Medicare home health services
This code represents when a doctor or qualified healthcare provider officially certifies that a patient needs Medicare-covered home health services. The doctor reviews the patient's home health plan of care, communicates with the home health agency, and reviews status reports to confirm the patient qualifies for these services. This certification process happens without the patient being present during the doctor's review and approval process.
G8417Documentation that BMI is above normal range with follow-up plan recorded
This code indicates that a healthcare provider has calculated and documented that a patient's Body Mass Index (BMI) is above normal parameters (typically meaning overweight or obese range) and has also documented a specific follow-up plan to address this finding. BMI is a measurement that uses height and weight to estimate body fat and assess weight categories. This code represents the administrative tracking of proper documentation practices rather than a specific medical procedure or treatment.
A6403Medium-sized sterile gauze pad (larger than 16 square inches, up to 48 square inches)
This code represents a sterile gauze pad used for wound care and medical dressings. The gauze is non-impregnated (meaning it doesn't contain medications or other substances), sterile to prevent infection, and measures between 16 and 48 square inches in size. It does not have an adhesive border, so it would typically need to be secured with tape or other means. This is a single-use dressing item.
A4450Non-waterproof medical tape (18 square inches)
This code represents non-waterproof medical tape measured in units of 18 square inches. This type of tape is used for securing medical dressings, bandages, or medical devices to the skin. Unlike waterproof tape, this version is not designed to resist water or moisture, making it suitable for dry conditions or temporary applications where water resistance is not required.
G8756Documentation code indicating blood pressure was not measured during a medical visit
This is a tracking code used by healthcare providers to document that a patient's blood pressure was not measured during a medical encounter, and no specific reason was provided for why the measurement was not taken. This code helps healthcare systems monitor quality of care and ensure important vital signs like blood pressure are being checked when appropriate.
A4604Heated tubing for sleep apnea machines
This is a special type of tubing that connects to a CPAP, BiPAP, or other positive airway pressure machine used to treat sleep apnea and breathing disorders. The tubing has a built-in heating element that warms the air as it travels from the machine to your mask, helping to prevent condensation (water buildup) in the tube and making breathing more comfortable during sleep therapy.
A4223Medical supplies for IV infusion therapy without an external pump
This code covers the medical supplies needed to deliver medications or fluids directly into your bloodstream through an IV line, but without using an external infusion pump. This includes items like IV bags, cassettes, tubing, and other necessary supplies for the infusion process. The actual medications being given are billed separately from these supply costs.
A7035Headgear component for sleep apnea breathing machines
This code covers the headgear (straps and fitting components) that holds the mask in place for positive airway pressure (PAP) devices. These devices are commonly used to treat sleep apnea by delivering pressurized air to keep airways open during sleep. The headgear is an essential component that ensures the mask stays properly positioned throughout the night for effective treatment.
G8482Flu vaccination given or previously received
This code is used to document that you either received a flu (influenza) vaccination during your current visit, or that you had already received one previously. The flu vaccine helps protect against seasonal influenza viruses and is typically recommended annually for most people 6 months and older.
G0008Administration of flu vaccine
This code represents the service of giving a flu (influenza) vaccine to a patient. It covers the healthcare provider's work in administering the vaccine injection, including preparation, injection technique, and immediate monitoring. This is separate from the cost of the vaccine itself and specifically covers the administration service.
G9903Documentation that patient was screened for tobacco use and identified as a non-tobacco user
This code is used by healthcare providers to document that they have screened a patient for tobacco use (such as cigarettes, cigars, chewing tobacco, or other tobacco products) and determined that the patient does not currently use tobacco. This screening is part of routine preventive healthcare and helps providers track tobacco use status for health monitoring and quality reporting purposes.
C9803COVID-19 specimen collection at hospital outpatient clinic
This code represents the collection of a specimen (such as a nasal swab, saliva, or other sample) for COVID-19 testing at a hospital outpatient clinic. The specimen is collected to test for SARS-CoV-2, the virus that causes COVID-19. This code covers the collection process itself, regardless of what type of specimen is collected.
G0121Colonoscopy screening for colon cancer in average-risk individuals
This code represents a colonoscopy procedure performed specifically to screen for colorectal (colon and rectal) cancer in individuals who are considered average risk. This means the patient does not have factors that would classify them as high risk for developing colorectal cancer, such as a strong family history, personal history of polyps or inflammatory bowel disease, or certain genetic conditions. The colonoscopy is done as a preventive measure to detect cancer or precancerous changes early, when treatment is most effective.
G0383Level 4 emergency department visit at a Type B emergency department
This code represents a Level 4 emergency department visit, which is typically for more complex or severe medical conditions that require significant evaluation and treatment. The visit takes place at a Type B emergency department, which is a facility that meets specific licensing and operational requirements - it must be either licensed as an emergency department by the state, publicly advertised as providing emergency care without appointments, or provide at least one-third of its services for emergency conditions without requiring scheduled appointments.
G044715-minute face-to-face counseling session for obesity management
This code represents a 15-minute, in-person behavioral counseling session specifically focused on obesity management. During this session, a healthcare provider works directly with you to discuss strategies, behaviors, and lifestyle changes that can help with weight management and obesity-related health concerns. The counseling is educational and supportive, aimed at helping you develop healthier habits and behaviors.
G2023Collection of a specimen to test for COVID-19
This code represents the collection of a specimen (such as a nasal swab, throat swab, saliva sample, or other body fluid) that will be used to test for SARS-CoV-2, the virus that causes COVID-19. This code covers the actual process of collecting the sample, regardless of what type of specimen is collected or where it's collected from on the body.
G8428Documentation that current medications were not obtained, updated, or reviewed
This code indicates that during your medical visit, your healthcare provider did not obtain, update, or review your current list of medications, and no specific reason was documented for why this important step was skipped. Maintaining an accurate, up-to-date medication list is a standard part of quality medical care to prevent drug interactions and ensure safe treatment.
G8984Assessment of current ability to carry, move, and handle objects during physical therapy
This code is used by physical therapists to document your current functional status regarding carrying, moving, and handling objects. It represents a standardized assessment that measures how well you can perform activities like lifting items, moving objects from one place to another, or manipulating things with your hands. This evaluation is conducted at the beginning of your therapy treatment and at regular intervals to track your progress over time.
A6238Large sterile wound dressing with adhesive border (16-48 square inches)
This code represents a hydrocolloid wound dressing that is sterile and designed to cover wounds. The dressing pad itself measures between 16 and 48 square inches (roughly 4x4 inches to 7x7 inches) and comes with an adhesive border of any size around the edges to help secure it to the skin. Hydrocolloid dressings are specialized wound covers that help maintain a moist healing environment. Each unit of this code represents one individual dressing.
G8418Documentation that BMI is below normal range with follow-up plan recorded
This code indicates that a healthcare provider has calculated and documented that a patient's Body Mass Index (BMI) is below the normal healthy range (typically under 18.5), and has also documented a specific follow-up plan to address this low BMI. BMI is a measurement that uses height and weight to assess if someone is underweight, normal weight, overweight, or obese.
G8979Documentation of mobility and walking goals during therapy treatment
This code is used by healthcare providers to document and track your mobility goals during physical therapy or rehabilitation. It specifically tracks your ability to walk and move around, recording your projected goals at the start of therapy, progress during treatment intervals, and final status when therapy ends. This helps ensure your therapy is meeting its intended objectives for improving your walking and mobility.
G9654Monitored anesthesia care (MAC) - a type of anesthesia where you remain conscious but relaxed during a medical procedure
Monitored anesthesia care (MAC) is a specific type of anesthesia service where an anesthesia provider continuously monitors your vital signs and level of consciousness during a medical procedure. Unlike general anesthesia where you are completely unconscious, MAC allows you to remain awake or in a light sleep while receiving sedation medications to keep you comfortable and relaxed. The anesthesia provider stays with you throughout the procedure to ensure your safety and adjust medications as needed.
G0103Blood test to screen for prostate cancer using PSA (prostate-specific antigen)
This is a screening test that measures the level of prostate-specific antigen (PSA) in your blood. PSA is a protein produced by the prostate gland, and elevated levels may indicate the presence of prostate cancer. This test is used as a screening tool to help detect prostate cancer early, before symptoms appear. The test involves a simple blood draw and is typically recommended for men at certain ages or with risk factors for prostate cancer.
G8432Documentation that depression screening was not performed, with no reason provided
This code indicates that a healthcare provider did not document performing a depression screening during a patient visit, and no reason was given for why the screening was not done. Depression screenings are routine questionnaires or assessments used to identify patients who may be experiencing depression. This code is used for quality reporting purposes to track when these screenings are missed without documented justification.
J2405Ondansetron injection - medication given by injection to prevent nausea and vomiting
This code represents an injection of ondansetron hydrochloride, a medication commonly used to prevent or treat nausea and vomiting. The code covers the cost per 1 milligram of the medication when given by injection (into a vein, muscle, or under the skin). Ondansetron works by blocking certain signals in the body that trigger nausea and vomiting. This injectable form is typically used when oral medications cannot be taken or when faster relief is needed.
Q3014Fee charged by a healthcare facility for providing the location and equipment for a telehealth appointment
This code represents the facility fee charged when a healthcare facility serves as the originating site for a telehealth visit. The originating site is where you, as the patient, are physically located during the telehealth appointment. This facility provides the necessary equipment, internet connection, and space for you to connect with a healthcare provider who may be located elsewhere. The fee covers the facility's costs for maintaining telehealth technology and providing technical support during your remote consultation.
G8918Documentation that a patient did not receive a preoperative order for IV antibiotics to prevent surgical site infection
This code indicates that a patient undergoing surgery did not have a preoperative order written for intravenous (IV) antibiotics that are typically given before surgery to help prevent surgical site infections (SSI). This is a quality reporting code used to track whether proper infection prevention protocols were followed. The absence of such an order may indicate a gap in standard surgical care protocols, as IV antibiotics before surgery are a common practice to reduce the risk of infection at the surgical site.
G0283Electrical stimulation therapy (unattended) for conditions other than wound healing
This code covers electrical stimulation therapy that runs automatically without a healthcare provider present. The electrical stimulation is applied to one or more areas of your body for therapeutic purposes, but specifically excludes wound care treatments. This therapy is delivered as part of your overall treatment plan and uses electrical currents to help with various medical conditions such as pain management, muscle stimulation, or other therapeutic goals as determined by your healthcare provider.
G8981Assessment of ability to change and maintain body positions during physical therapy
This code is used by physical therapists to document and track a patient's current functional ability to change positions (like sitting to standing, lying down to sitting up) and maintain those positions. It measures this ability at the start of therapy and at regular check-in points to monitor progress throughout treatment.
