ICD-10 Code G47.33 – Obstructive Sleep Apnea (OSA)
Most Commonly Used Code: G47.33 is billable and commonly used for obstructive sleep apnea, where breathing repeatedly stops due to airway obstruction during sleep.
Why ICD-10 Codes for Sleep Apnea Are Important?
Obstructive Sleep Apnea (OSA) is one of the most prevalent sleep disorders, leading to interrupted breathing and poor sleep quality. The ICD-10 code G47.33 is billable and ensures providers, hospitals, and billing teams record accurate diagnoses for treatment planning, sleep studies, and insurance reimbursement.
Accurate diagnosis reporting
Supports consistent documentation of OSA, guiding treatment such as CPAP therapy, oral appliances, or surgery.
Medical billing & insurance claims
Accurate use of G47.33 ensures insurers reimburse for diagnostic sleep studies, CPAP machines, and OSA-related treatments.
Research & public health tracking
Precise coding helps track prevalence, risk factors, and associations with hypertension, obesity, and cardiovascular disease.
Common ICD-10 Codes Related to Sleep Apnea
Obstructive Sleep Apnea (OSA)
Adult and Pediatric Presentations
Central sleep apnea – G47.31
Breathing stops due to brain signaling issues
Mixed/other sleep apnea – G47.39
Combination of obstructive and central types
Sleep apnea, unspecified – G47.30
Sleep apnea without further specification
Obstructive sleep apnea – G47.33
Airway obstruction during sleep causing apnea/hypopnea
When to Use These Codes
- G47.33: Use when obstructive sleep apnea is confirmed by sleep study.
- G47.31: Use when central sleep apnea is diagnosed.
- G47.39: Use when mixed/other sleep apnea is present.
- G47.30: Use if sleep apnea is noted but type not specified.
Tip: Always code to the highest specificity based on sleep study results and provider documentation.
Related Codes & Their Synonyms

Common Synonyms for ICD-10 Code G47.33 (Obstructive Sleep Apnea)
Understanding Sleep Apnea
Sleep apnea is a disorder where breathing repeatedly stops and starts during sleep.
Mild Obstructive Sleep Apnea
AHI (Apnea–Hypopnea Index) of 5–15 events/hour
Moderate Obstructive Sleep Apnea
AHI of 15–30 events/hour
Severe Obstructive Sleep Apnea
AHI greater than 30 events/hour
Obstructive Sleep Apnea (OSA):
Caused by airway collapse.
Central Sleep Apnea (CSA):
Caused by brain signaling issues.
Mixed Sleep Apnea:
Combination of both.
Untreated sleep apnea increases risks of high blood pressure, heart disease, stroke, and daytime fatigue.
