Healthcare Common Procedure Coding System

Last updated: 10/30/2025

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 is a special type of tubing that connects to a CPAP, BiPAP, or other positive airway pressure machine used to treat sleep apnea and breathing disorders. The tubing has a built-in heating element that warms the air as it travels from the machine to your mask, helping to prevent condensation (water buildup) in the tube and making breathing more comfortable during sleep therapy.

Additional Information

This is a replacement supply item for sleep apnea equipment. The heated tubing helps maintain optimal humidity and temperature for more comfortable sleep therapy treatment.
