Summary & Overview

HCPCS A7507: Tracheostoma HME Filter Holder with Integrated Filter

HCPCS Level II code A7507 identifies a filter holder and integrated filter (without adhesive) designed for use in a tracheostoma heat and moisture exchange (HME) system. The item is a single-unit consumable accessory used in tracheostomy care to help maintain inspired air humidity and temperature, supporting airway protection and secretion management. Nationally, proper coding of HME components affects durable medical equipment (DME) billing, supplier reimbursement, and continuity of care for patients relying on tracheostomies.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of coding context, typical sites of service, and how A7507 fits into respiratory device supply chains. The publication covers benchmarking of coverage and reimbursement practices, common billing modifiers observed in claims, and relevant policy updates that influence provider documentation and claim submission. Clinical context is provided to clarify device function and typical clinical scenarios for use. Where input data is absent, the report notes "Data not available in the input."

Billing Code Overview

HCPCS Level II code A7507 describes a filter holder and integrated filter without adhesive intended for use in a tracheostoma heat and moisture exchange (HME) system, supplied as a single unit (each). The product is a consumable component of HME systems used to preserve humidity and warmth of inspired air for patients with a tracheostomy.

Service Type: Durable medical equipment accessory / respiratory care supply

Typical Site of Service: Home, outpatient clinics, long-term care facilities, and inpatient hospital settings where tracheostomy care and respiratory humidification are managed

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with a permanent or temporary tracheostomy who requires a heat and moisture exchanger (HME) system to reduce airway crusting, improve humidification, and filter particulates. The provider supplies a replacement A7507 filter holder and integrated filter without adhesive for use in a tracheostoma HME system. Clinical workflow: the respiratory therapist or durable medical equipment (DME) supplier evaluates the tracheostomy site, confirms size and compatibility with the patient’s HME housing, documents the device serial or model and patient need, dispenses the A7507 item, instructs the patient or caregiver on insertion, replacement frequency, and routine stoma hygiene, and records device delivery in the medical record. Typical sites of service include outpatient durable medical equipment supplier locations, home health visits, long-term acute care hospitals, skilled nursing facilities, and hospital outpatient clinics where tracheostomy care and supplies are managed.
