Summary & Overview
HCPCS G8853: Positive Airway Pressure Therapy Not Prescribed
HCPCS Level II code G8853 identifies clinical encounters where positive airway pressure (PAP) therapy was evaluated but ultimately not prescribed. Nationally, clear coding for non-prescription outcomes of PAP assessment matters for care documentation, utilization tracking, and medical necessity audits. Accurate use of this code helps distinguish diagnostic or consultative encounters from billed therapy delivery.
Key payers commonly referenced for coverage and billing practices include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the code, common sites of service, and the implications for billing workflows. The publication reviews benchmarks and policy-relevant considerations that affect how payers and providers document PAP-related evaluations, and it summarizes clinical scenarios that typically lead to non-prescription outcomes.
This resource is intended for clinicians, coding staff, and compliance professionals seeking a national perspective on documenting PAP evaluation visits that do not result in a PAP prescription. Data not available in the input.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult evaluated in a sleep medicine clinic or pulmonary practice for symptoms suggestive of obstructive sleep apnea (OSA) such as loud snoring, witnessed apneas, daytime sleepiness, and morning headaches. The patient completes an overnight polysomnography or home sleep apnea test demonstrating mild-to-moderate OSA or borderline results. During the follow-up visit, the clinician determines that positive airway pressure therapy is not appropriate or not prescribed because of one or more of the following: patient refusal, intolerance to PAP during a supervised titration, alternative treatment plans (oral appliance, positional therapy, weight loss, surgical referral), or insufficient severity on diagnostic testing. The clinical workflow includes documenting the diagnostic test results, describing prior attempts or trials of PAP (if any), counseling about risks and benefits of PAP and alternative therapies, and entering the billing code G8853 to indicate that positive airway pressure therapy was considered but not prescribed.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service | Use when a distinct E/M visit is performed the same day the decision is made not to prescribe PAP and the visit meets E/M documentation requirements |
