Summary & Overview
HCPCS E0562: Heated Humidifier for Positive Airway Pressure Devices
HCPCS Level II code E0562 denotes a heated humidifier used with positive airway pressure devices. The code captures durable medical equipment that supplies heated humidification to patients using CPAP, BiPAP, or other positive airway pressure therapies, improving mucosal comfort and potentially adherence. Nationally, this code matters because it affects durable medical equipment coverage decisions, home respiratory therapy billing, and supply provisioning for patients with sleep-disordered breathing or other indications for PAP therapy.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what the code represents, typical sites of service, and the clinical context for heated humidification with PAP devices. The publication outlines benchmarking and coverage considerations, common modifier usage (listed separately), and the relationship between E0562 and related respiratory equipment codes. It also summarizes documentation and billing points relevant to suppliers and billing staff.
This summary is intended for a national audience of billing professionals, DME suppliers, and health policy analysts seeking clarity on code purpose, payer coverage landscape, and practical billing context for heated humidifiers paired with positive airway pressure systems. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with diagnosed obstructive sleep apnea (OSA) uses a positive airway pressure (PAP) device at home. During a sleep medicine clinic visit, the clinician confirms continued PAP therapy and documents complaints of nasal dryness, throat irritation, or recurrent mask leaks. The durable medical equipment (DME) supplier arranges delivery of a heated humidifier (E0562) to be used with the patient’s PAP device to improve comfort and adherence. Clinical workflow: ordering clinician documents medical necessity and relevant ICD-10 diagnosis; DME supplier verifies PAP device compatibility, obtains prior authorization if required, arranges patient education on humidifier setup and cleaning, delivers the device to the patient’s home, and updates the medical record with delivery and patient instruction details.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier (default) | Use when no additional reporting modifier is required for the furnished DME. |
22 | Increased procedural services | Rarely used for DME; may be used if unusually extensive documentation or complexity is required for setup and education beyond typical. |
