Showing 22 of 472 ICD-10 codes

Benign (non-cancerous) skin growth on the left upper eyelid

This code refers to a benign skin tumor or growth located on the left upper eyelid. 'Benign' means the growth is not cancerous and will not spread to other parts of the body. These growths can include various types of skin lesions such as moles, cysts, or other non-harmful skin formations. While not dangerous, they may be removed for cosmetic reasons, if they interfere with vision, or cause discomfort. An ophthalmologist (eye specialist) would typically evaluate and treat these conditions since they involve the delicate eyelid area.

Lower back pain with nerve pain shooting down the right leg

This code describes a condition where you have both lower back pain (lumbago) and sciatica affecting your right side. Lumbago refers to pain in the lower back area, while sciatica is pain that travels along the sciatic nerve - typically starting in your lower back and radiating down through your buttock and into your right leg. This combination often occurs when something in your spine (like a herniated disc, bone spur, or muscle tension) puts pressure on or irritates the sciatic nerve roots. The pain may feel sharp, burning, or tingling, and can range from mild to severe. You might also experience numbness or weakness in your right leg or foot.

Documentation of past medical conditions or treatments that may be relevant to current care

This code indicates that you have a personal history of certain medical conditions, treatments, or circumstances that your healthcare provider considers important for your current medical care. This is not a current active problem, but rather documentation of something from your past that could influence treatment decisions or monitoring. Your doctor uses this code to keep track of your complete medical history, which helps ensure you receive the most appropriate care. The specific condition being referenced would be detailed in your medical records.

Benign (non-cancerous) skin growth on the eyelid

This code refers to a benign neoplasm (non-cancerous growth) of the skin of the eyelid. These are typically harmless skin growths that can appear on or around the eyelid area. Common examples include skin tags, moles, or small cysts. While these growths are not cancerous and generally don't spread, they may be removed if they cause irritation, affect vision, or for cosmetic reasons. An ophthalmologist (eye specialist) would typically evaluate and treat these conditions since they involve the delicate eyelid area.

Former cigarette addiction - now in recovery

This code indicates that you previously had a nicotine addiction specifically to cigarettes, but you are now in remission, meaning you have successfully quit smoking and are no longer actively dependent on nicotine. This diagnosis recognizes your past struggle with cigarette addiction while acknowledging your current smoke-free status. Healthcare providers use this code to document your smoking history, which remains medically relevant for ongoing health monitoring and care planning, even though you are no longer actively smoking.

Varicose veins in both legs causing pain

This code describes a condition where you have enlarged, twisted veins (varicose veins) in both of your lower legs that are causing you pain. Varicose veins occur when the valves in your leg veins don't work properly, causing blood to pool and the veins to become swollen and visible under the skin. The pain associated with this condition can range from aching and throbbing to cramping sensations, and may worsen after long periods of standing or sitting. This is a common condition that affects many people and can be managed with various treatment options.

Benign (non-cancerous) mole or skin growth on the eyelid

This code refers to a benign nevus, which is a non-cancerous mole or pigmented skin growth located on the eyelid. These are common, harmless skin lesions that contain clusters of pigment-producing cells called melanocytes. While they are typically not dangerous, eyelid nevi may be monitored or removed for cosmetic reasons, if they interfere with vision, or if there are any changes in appearance that warrant evaluation. An ophthalmologist or dermatologist can assess whether any treatment is needed.

Inflamed seborrheic keratosis - a common, non-cancerous skin growth that has become irritated or inflamed

Seborrheic keratoses are very common, benign (non-cancerous) skin growths that appear as brown, black, or tan patches on the skin. They often look waxy, scaly, or slightly raised and are sometimes called 'barnacles' because of their appearance. When these growths become inflamed, they may appear red, swollen, tender, or irritated. This inflammation can occur from friction (like clothing rubbing against them), scratching, or other minor trauma. While seborrheic keratoses are harmless, inflamed ones may be uncomfortable and should be evaluated by a healthcare provider to confirm the diagnosis and discuss treatment options if needed.

Routine screening visit to check for a specific health condition

This code is used when you visit your doctor for preventive screening to check for a particular health disorder or condition, even though you don't currently have symptoms. This is different from a diagnostic visit where you're being examined because of symptoms you're experiencing. Screening visits are proactive healthcare measures designed to catch potential health issues early, when they're most treatable. The specific disorder being screened for would be documented elsewhere in your medical record. This type of visit is typically part of routine preventive care and may be covered by insurance as a preventive service.

Blood test showing higher than normal levels of PSA, a protein made by the prostate gland

This code indicates that a blood test called PSA (Prostate Specific Antigen) showed levels higher than the normal range. PSA is a protein produced by cells in the prostate gland, and small amounts normally circulate in the blood. Elevated PSA levels can have several causes, including prostate cancer, benign prostate enlargement (BPH), prostate infection, recent medical procedures involving the prostate, or even vigorous physical activity. An elevated PSA doesn't automatically mean cancer - it's a screening tool that helps doctors determine if further testing is needed. Your doctor will consider your PSA level along with other factors like your age, family history, and physical exam results to decide on next steps.

A birth defect affecting the heart's structure that hasn't been specifically identified

This code indicates that a person was born with a heart defect, but the specific type of defect hasn't been determined or specified in the medical records. Congenital heart defects are structural problems with the heart that are present from birth. They can affect the heart's walls, valves, or blood vessels. The term 'unspecified' means that while doctors know there is a heart malformation, they either haven't identified the exact type yet or the medical documentation doesn't include those specific details. These conditions can range from very mild defects that may never cause problems to more serious ones that require ongoing medical care or treatment.

Bipolar disorder diagnosis without specific subtype identified

This code indicates a diagnosis of bipolar disorder, a mental health condition that causes unusual shifts in mood, energy, and activity levels. People with bipolar disorder experience periods of unusually intense emotion, changes in sleep patterns and activity levels, and uncharacteristic behaviors. These distinct periods are called 'mood episodes.' The 'unspecified' designation means that while bipolar disorder has been diagnosed, the specific type (such as Bipolar I or Bipolar II) has not been determined or documented at this time. This might be used during initial evaluation or when there isn't enough information yet to specify the exact subtype.

Low back pain

This code represents low back pain, which is pain located in the lower portion of your back (lumbar region). This is a very common condition that can range from mild discomfort to severe pain that affects your daily activities. The pain may be caused by muscle strain, ligament sprain, disc problems, arthritis, or other spine-related issues. It can be acute (sudden onset, short-term) or chronic (long-lasting). The pain might stay in one spot or spread to your buttocks, hips, or legs.

Curved spine (scoliosis) in the chest area caused by chest/lung problems

Thoracogenic scoliosis is a sideways curvature of the spine in the chest (thoracic) region that develops as a result of problems with the chest cavity, lungs, or surrounding tissues. Unlike other types of scoliosis that may have unknown causes, this specific type occurs when chest or lung conditions cause the spine to curve abnormally. The curvature typically develops as the body tries to compensate for underlying chest or respiratory issues. This condition affects the middle portion of the spine where the ribs attach, and may impact breathing, posture, and overall spinal alignment.

Joint inflammation and skin condition caused by psoriatic arthritis, type not specified

Arthropathic psoriasis is a condition where you have both psoriasis (a skin condition that causes red, scaly patches) and arthritis (joint inflammation and pain) occurring together. This is also known as psoriatic arthritis. The 'unspecified' part means the doctor hasn't identified which specific type or pattern of psoriatic arthritis you have. This condition can affect various joints in your body, causing pain, stiffness, and swelling, while also causing skin symptoms. It's an autoimmune condition where your immune system mistakenly attacks healthy joints and skin tissue.

Chronic bladder wall inflammation without blood in urine

Interstitial cystitis is a chronic condition where the bladder wall becomes inflamed and irritated. This causes symptoms like frequent urination, urgent need to urinate, and pelvic pain or pressure. The 'without hematuria' part means there is no visible blood in the urine. This is a long-term condition that can significantly impact quality of life, but it can be managed with various treatments including dietary changes, medications, and sometimes procedures to help reduce bladder inflammation and pain.

Neck pain

Cervicalgia is the medical term for neck pain. This code is used when a patient experiences pain in the cervical spine area (the neck region). The pain can range from mild discomfort to severe pain and may be caused by various factors such as muscle strain, poor posture, injury, or other underlying conditions affecting the neck area.

Other specified abnormal levels or types of proteins in blood plasma

This code indicates that blood tests have found abnormal levels or types of proteins in your blood plasma (the liquid part of blood). These are specific protein abnormalities that don't fit into other more common categories. Plasma proteins include substances like albumin, globulins, and other important proteins that help with blood clotting, immune function, and maintaining proper fluid balance in your body. The abnormality has been identified and documented but represents a less common type that requires this specific diagnostic code.

Self-inflicted skin condition (factitial dermatitis)

Factitial dermatitis is a skin condition where lesions or wounds are intentionally created or worsened by the patient themselves. This can involve scratching, picking, rubbing, or applying substances to the skin. The resulting skin damage appears artificial or self-induced rather than from a natural disease process. This condition may be related to psychological factors, stress, or compulsive behaviors.

Initial medical visit for injury caused by being struck by a dog

This code is used to document the first time a patient seeks medical care for an injury that occurred when they were struck by a dog. This is an external cause code that describes how the injury happened, not what specific injury occurred. It would be used alongside other codes that describe the actual injuries sustained (such as cuts, bruises, or fractures). The 'initial encounter' designation means this is the first time the patient is receiving treatment for this particular incident.

Long-term effects from an unspecified nutritional deficiency

This code represents the lasting health effects or complications that result from a nutritional deficiency where the specific type of deficiency was not identified or documented. Sequelae refers to conditions that are the consequence of a previous disease or injury. This would apply to ongoing health problems that developed as a result of not getting enough of certain nutrients, vitamins, or minerals in the past, but the exact nutritional deficiency that caused these effects is not specified in the medical record.

Pain in the middle back (thoracic spine)

This code indicates pain located in the thoracic spine, which is the middle portion of your back that includes the 12 vertebrae between your neck and lower back. The thoracic spine is where your ribs attach to your backbone. This code specifically describes pain in this region without specifying the underlying cause of the pain.
