Summary & Overview
HCPCS Level II A7506: Adhesive Disc for Tracheostoma Heat & Moisture Exchange
HCPCS Level II code A7506 identifies an adhesive disc used with heat and moisture exchange systems and tracheostoma valves, a small but essential accessory in tracheostomy management and respiratory humidification. Nationally, the code matters because it standardizes billing for an item that supports airway humidification, reduces risk of skin irritation, and secures device interfaces at the stoma.
Key payers in national coverage and reimbursement discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the adhesive disc, typical sites of service where it is used, and which payers commonly appear in policy and coverage considerations. The publication also outlines available benchmarks, relevant coding relationships, and policy or billing updates where available.
This summary equips providers, billing staff, and policy analysts with the context needed to identify where A7506 fits within durable medical equipment and tracheostomy supply workflows, and what to expect in payer interactions and documentation requirements. Data not available in the input is clearly noted where applicable.
Billing Code Overview
HCPCS Level II code A7506 describes an adhesive disc used with a heat and moisture exchange system and/or a tracheostoma valve. The item is a single adhesive disc, intended to secure or interface respiratory devices at a tracheostoma site.
Service Type: Durable medical equipment accessory for tracheostomy care and humidification systems
Typical Site of Service: Outpatient clinics, home health settings, long-term care facilities, and other non-acute care environments where tracheostomy management and respiratory humidification are provided.
Clinical & Coding Specifications
Clinical Context
A typical adult patient with a permanent tracheostomy visits an outpatient durable medical equipment (DME) clinic or a respiratory therapy clinic to obtain replacement supplies. The patient uses a heat and moisture exchange (HME) system and a tracheostoma valve for airway humidification and speech facilitation. The clinician inspects the tracheostoma and HME device, confirms proper fit and skin integrity, and supplies an adhesive disc to secure the HME or valve to the peristomal skin. The supply is documented in the patient record with the item A7506 (adhesive disc for use in a heat and moisture exchange system and/or with tracheostoma valve, any type each), quantity dispensed, supplier NPI, and diagnosis linking the need for a tracheostomy-related accessory (for example, tracheostomy status, chronic respiratory failure, or laryngeal dysfunction). Typical workflow includes verifying coverage and prior authorization if required by the payer, fitting the adhesive disc to the HME or valve, providing patient education on application and skin care, and arranging follow-up for supply replacement or skin assessment.
