Healthcare Common Procedure Coding System

Last updated: 10/3/2025

What is a HCPCS Code?

HCPCS (Healthcare Common Procedure Coding System) codes are used to identify medical procedures, supplies, and services for billing purposes. These codes help standardize how healthcare services are reported and billed across different providers and insurance companies.

Detailed Description

This code covers nasal interface devices (either mask-style or cannula/tube-style) that connect to positive airway pressure machines like CPAP or BiPAP devices. These devices deliver pressurized air through your nose to help keep your airways open during sleep or breathing treatment. The interface may include a head strap to keep it securely in place.

Additional Information

This is a replacement or initial supply item for patients using CPAP, BiPAP, or other positive airway pressure devices. The nasal interface is a key component that must fit properly for effective treatment.
