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 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 part that needs to be changed periodically for hygiene and proper function.
Additional Information
Water chambers should be replaced regularly for optimal hygiene and device performance. Check with your equipment supplier about replacement frequency and compatibility with your specific device model.
