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 represents a disposable filter that is used with positive airway pressure devices, commonly known as CPAP, BiPAP, or other PAP machines. These filters help keep the air clean by removing dust, pollen, and other particles before the air reaches your airways during sleep therapy treatment. The filter is designed to be replaced regularly as part of maintaining your PAP equipment.

Additional Information

Filters are typically replaced monthly or as directed by equipment manufacturer. Regular replacement helps maintain air quality and equipment performance.
