Prior Authorization

Prior Auth Required

At least one active policy explicitly requires prior authorization (high confidence)

Documentation Required

A Standard Written Order (SWO) must be communicated to the supplier before a claim is submitted; for items requiring Written Order Prior to Delivery (WOPD), a signed SWO/WOPD must be received before delivering the DMEPOS item.
For DMEPOS base items that require a WOPD and have separately billed options/accessories/supplies, the WOPD must list the base item (and may list associated items) prior to delivery; separate billing without a completed and signed WOPD will be denied.

Suppliers must maintain proof of delivery (POD) documentation in their files and make POD available to the Medicare contractor upon request.

Claims must meet coding guidelines in CMS HCPCS guidelines, LCDs, LCD-related Policy Articles, and DME MAC articles; refer to the LCD-related Standard Documentation Requirements Article and LCD-related Policy Article and the Supplier Manual for additional documentation details.

Medical records documentation may be required to assess whether the member meets the clinical criteria for coverage.

For high-frequency chest compression systems: documentation of 'well-documented failure of standard treatments' to adequately mobilize retained secretions is required (i.e., evidence that standard treatments have been attempted and were inadequate).

Key Coverage Criteria

HFCWO device (HCPCS E0483) is covered only when the beneficiary meets at least one qualifying diagnosis (cystic fibrosis, confirmed bronchiectasis, or a listed neuromuscular disease) AND there is well-documented failure of standard treatments to adequately mobilize retained secretions.
Diagnosis of cystic fibrosis (see LCD-related Policy Article for applicable ICD-10 codes).
Diagnosis of bronchiectasis confirmed by high-resolution, spiral, or standard CT scan and characterized by either daily productive cough for at least 6 continuous months or more than 2 exacerbations per year requiring antibiotic therapy.
Beneficiary has one of the listed neuromuscular disease diagnoses: post-polio, acid maltase deficiency, anterior horn cell diseases, multiple sclerosis, quadriplegia, hereditary muscular dystrophy, myotonic disorders, other myopathies, or paralysis of the diaphragm (see LCD-related Policy Article for applicable ICD-10 codes).
There must be well-documented failure of standard airway clearance treatments to adequately mobilize retained secretions prior to HFCWO coverage.
High-frequency chest wall oscillation (HFCWO) system rental for 2 months is medically necessary for management of neuromuscular diseases, bronchiectasis, and cystic fibrosis when criteria are met.
