Documentation Required

A completed Standard Written Order (SWO) must be communicated to the supplier before claim submission; for DMEPOS base items requiring WOPD, a signed SWO/WOPD must be received before delivery.
Proof of delivery (POD) documentation must be maintained by suppliers and made available to the Medicare contractor upon request; lack of POD may lead to denial.

Medical record documentation must substantiate medical necessity for non-routine catheter changes, specialty/all-silicone/Coude catheters, continuous irrigation (including rate and duration), and any quantity greater than policy-specified amounts; records must be available upon request.

Continued coverage for the inFlow device beyond 3 months requires a treating practitioner re-evaluation between day 31 and day 91 documenting in-person encounter showing symptom improvement and verification of beneficiary adherence to device use; if re-evaluation occurs after day 91 and documents benefit, coverage commences as of that evaluation date.

Key Coverage Criteria

Items are covered if they are in an eligible Medicare benefit category, are reasonable and necessary for diagnosis/treatment or to improve function of a malformed body member, and meet applicable Medicare statutory/regulatory requirements.
Routine indwelling catheter maintenance: one indwelling catheter unit (e.g., A4314/A4315/A4316/A4340/A4344 variants) per month is covered.
Non-routine indwelling catheter changes are covered when documentation substantiates medical necessity, including accidental removal, catheter malfunction, obstruction (encrustation/mucous plug/blood clot), or history of recurrent obstruction/UTI requiring scheduled changes >1/month.
Specialty indwelling catheters (A4340) or all-silicone catheters (A4344, A4312, A4315) are covered when indwelling catheter criteria are met and medical record documents specific need (e.g., recurrent encrustation, inability to pass straight catheter, latex sensitivity).
Three-way indwelling catheters (A4346 alone or with A4313/A4316) are covered only when continuous bladder irrigation is reasonable and necessary.
One catheter insertion tray is covered per episode of indwelling catheter insertion; one intermittent catheter with insertion supplies is covered per episode of reasonable and necessary sterile intermittent catheterization.
