A7046 - Replacement water chamber for CPAP/BiPAP humidifier
Healthcare Common Procedure Coding System
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 the cost of a replacement water chamber (tank) that is part of a humidifier system used with positive airway pressure devices like CPAP or BiPAP machines. The water chamber holds water that gets heated to add moisture to the air you breathe through your sleep apnea device, making therapy more comfortable. This is a single replacement unit when your current water chamber needs to be replaced due to wear, damage, or medical necessity.
Additional Information
Water chambers typically need replacement every 6-12 months or as recommended by your healthcare provider. Always use distilled water in the chamber to prevent mineral buildup and ensure proper function.
