Summary & Overview
HCPCS A7014: Nondisposable Filter for Aerosol Compressor or Ultrasonic Generator
HCPCS Level II code A7014 identifies a nondisposable filter used with aerosol compressors or ultrasonic generators, representing a reusable component of respiratory therapy delivery systems. Nationally, standardized coding for reusable respiratory filters matters for billing consistency, device classification, and claims processing across Medicare and major commercial payers. Clarity about this code supports accurate supply reimbursement and inventory management for providers delivering aerosolized treatments.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of how A7014 is defined, the clinical context for its use, and the settings where the item is most commonly deployed, such as home health and outpatient respiratory therapy departments. The publication summarizes typical billing considerations and common modifiers used with durable medical equipment lines (modifiers list provided in metadata), notes standard sites of service, and explains where input data is unavailable.
This resource is intended for billing managers, clinical administrators, and policy analysts seeking a national perspective on coding and classification for nondisposable respiratory filters. It highlights practical implications for claims submission and documentation without offering clinical guidance or payer-specific directives.
Billing Code Overview

Service type: Durable medical equipment component for respiratory therapy
Typical site of service: Home health, outpatient clinics, and other settings where aerosolized respiratory treatments are delivered (for example, pulmonary function or respiratory therapy departments)
Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or pediatric individual requiring aerosolized medication via a compressor or ultrasonic nebulizer for management of respiratory conditions (for example, acute asthma exacerbation, chronic obstructive pulmonary disease exacerbation, cystic fibrosis with recurrent bronchospasm, or bronchiolitis). The clinician or respiratory therapist assembles the nebulizer system in an ambulatory clinic, hospital inpatient ward, emergency department, or home health visit. A nondisposable filter A7014 is attached to the aerosol compressor or ultrasonic generator to protect the device and reduce contamination during repeated treatments. Workflow: patient assessment and indication for aerosol therapy; selection and preparation of medication; assembly of compressor/ultrasonic generator with A7014 filter; administration of aerosolized treatment by mask or mouthpiece for the prescribed duration; monitoring for clinical response and adverse effects; cleaning, disinfection, or return-to-service procedures for the nondisposable filter per manufacturer instructions and facility infection-control policies. Typical sites of service include outpatient clinics, hospital inpatient units, emergency departments, and home health settings where reusable nebulizer filters are used.

| 22 | Increased procedural services | Use when substantially greater effort or time is required related to device setup or extended care related to aerosol therapy |
| 26 | Professional component | Use when billing separately for the professional interpretation/oversight component of a service associated with aerosol therapy (limited applicability) |
| 52 | Reduced services | Use when the service was partially reduced or not completed as originally planned |
| 53 | Discontinued procedure | Use when aerosol therapy was started but discontinued for patient safety reasons |
| 54 | Surgical care only | Rarely applicable; use if only the technical/device-related part is billed and another provider bills other portions |
| 55 | Postoperative management only | Rarely applicable; use if only post-treatment management is billed by a different provider |
| 62 | Two surgeons | Uncommon; use only when two qualified practitioners share responsibility for a component of care related to the procedure |
| 78 | Unplanned return to the operating/procedure room by the same physician following initial procedure | Use if patient requires an unplanned repeat procedure related to aerosol device malfunction or complication (rare) |
| 80 | Assistant surgeon | Use when an assistant surgeon legitimately assists with a related procedure |
| 82 | Assistant surgeon (when qualified resident surgeon not available) | Use in settings where an assistant is required and a resident is not available |
| AS | Physician assistant, nurse practitioner, or clinical nurse specialist services | Use when services associated with device setup or treatment are furnished by an advanced practice clinician and payer requires this modifier |
| NU | New equipment | Use when billing for a new nondisposable device component acquisition if payer policy requires distinction |
| QX | Assistant surgeon — assistant at surgery (payment based on specific rules) | Applied per payer rules when an assistant performs substantial portions of a procedure |
