International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code represents an office visit with your doctor to discuss or manage obstructive sleep apnea (OSA). OSA is a sleep disorder where your throat muscles relax too much during sleep, causing your airway to narrow or close completely. This leads to pauses in breathing that can happen many times throughout the night. These breathing interruptions cause your oxygen levels to drop and frequently wake you up, even if you don't remember waking. Common symptoms include loud snoring, gasping during sleep, morning headaches, daytime fatigue, and difficulty concentrating. This condition affects both adults and children and can lead to serious health problems if left untreated, including high blood pressure, heart disease, and diabetes.

Additional Information

Treatment typically involves lifestyle changes, CPAP machines, oral appliances, or in some cases surgery. Regular follow-up is important to ensure treatment effectiveness and prevent complications.
