Coverage and Medical Necessity Criteria
Reauthorization / Continued Use
Reauthorization (continued use) covered when ALL of the following are met:
See policy for documentation timeframe requirements.
There are no additional limitations listed for coverage of home intermittent positive pressure breathing (IPPB) devices beyond the specified authorization criteria and documentation requirements.
Use of IPPB is not appropriate when contraindications or precautions are present. Examples listed in the policy include: untreated tension pneumothorax, intracranial pressure (ICP) > 15 mm Hg, hemodynamic instability, recent facial/oral/skull or esophageal surgery, tracheoesophageal fistula, active hemoptysis, nausea, air swallowing, active untreated tuberculosis, radiographic evidence of bleb, and singulation (hiccups).

Provider Requirements, Authorization, and Documentation
Prior authorization required — rental only; limits on duration
Prior authorization is required for home IPPB devices; if approved the device is authorized as a rental only. Initial authorization is up to three (3) months, and subsequent reauthorization may be granted for up to twelve (12) months. This guideline is effective for prior authorization requests for HUSKY A-D on or after November 1, 2025.
- Authorization model: rental only
- Initial authorization: up to 3 months
- Reauthorization (subsequent): up to 12 months
- Policy effective date for prior authorizations: 11/01/2025
Conservative therapy required — try standard treatments first
Prior standard treatments must have been attempted and been unsuccessful before IPPB is considered. Examples include incentive spirometry, chest physiotherapy, deep breathing exercises, positive airway pressure therapy, postural drainage, and aerosol therapy; IPPB may also be considered when inability to clear secretions persists despite these treatments.
- Standard treatments for atelectasis unsuccessful (e.g., incentive spirometry, chest physiotherapy, deep breathing exercises, positive airway pressure therapy)
- Failure to respond to other treatments for secretion clearance (e.g., incentive spirometry, postural drainage, aerosol therapy)
Required documentation for authorization request
Submit a fully completed authorization request via the web portal, a signed prescription written within the past 3 months from an enrolled MD/PA/APRN, documentation from the ordering provider within the past 3 months supporting medical necessity per the Clinical Guidelines, and an attestation that the individual has no relative contraindications to IPPB.
- Completed authorization request via web portal
- Signed prescription within past 3 months from treating MD, PA, or APRN enrolled in CMAP
- Provider documentation within past 3 months supporting medical necessity per Clinical Guidelines
- Attestation that the individual does not have relative contraindications to IPPB
Denial triggers — contraindications and unmet criteria
Requests may be denied if the individual has listed contraindications or precautions to IPPB or if authorization criteria/medical necessity are not met. Examples of contraindications include untreated tension pneumothorax, intracranial pressure > 15 mm Hg, hemodynamic instability, recent facial/oral/skull/esophageal surgery, active hemoptysis, active untreated tuberculosis, radiographic bleb, air swallowing, nausea, tracheoesophageal fistula, or singulation (hiccups).
- Denial if authorization/medical necessity criteria are not satisfied
- Denial triggers: untreated tension pneumothorax; ICP > 15 mm Hg; hemodynamic instability
- Other contraindications/precautions: recent facial/oral/skull/esophageal surgery; tracheoesophageal fistula; active hemoptysis; nausea; air swallowing; active untreated tuberculosis; radiographic evidence of bleb; singulation (hiccups)
Clinical Background
Intermittent Positive Pressure Breathing (IPPB) provides short-term or intermittent mechanical ventilation via a mouthpiece or mask to enhance lung expansion, prevent atelectasis, assist in clearing airway secretions, and to facilitate delivery of aerosolized medications. Coverage decisions are individualized and require documentation that the patient (or caregiver) has been trained in device use and has no known contraindications prior to authorization.
Definitions and Terminology
OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
