Documentation Required
- Medical necessity for oxygen and oxygen equipment must be documented in the medical record according to the requirements of the related Local Coverage Determination (LCD).
- A treating practitioner's order is required to justify a change in equipment modality, and a beneficiary must sign an Advance Beneficiary Notice (ABN) when electing an upgrade that may not be covered.
- For a break-in-need that could restart a rental period, new medical necessity must be established and documented in the medical record.
- Suppliers must retain documentation of the initial date of service and rental history to calculate the RUL and rental-period eligibility.
Key Coverage Criteria
- Oxygen and oxygen equipment are covered under the Durable Medical Equipment (DME) benefit when reasonable and necessary as documented per the related Local Coverage Determination (LCD) and all Medicare statutory and regulatory requirements are met.
- When the reasonable useful lifetime (RUL) end date of stationary oxygen equipment occurs, the beneficiary may elect simultaneous replacement of both stationary and portable oxygen equipment, which starts a new 36-month rental period and a new RUL for both items.
- If portable oxygen use begins after stationary equipment use began, payment for the portable equipment may continue beyond the end of stationary equipment payments until 36 monthly rental payments have been made for the portable equipment.
- Non-invasive vascular studies (duplex scan, physiologic studies, plethysmography, transcranial Doppler) are covered when ordered by the treating or consulting practitioner and medically necessary to evaluate, diagnose, or manage vascular disease.
- Initial autogenous access vessel mapping should be billed with HCPCS codes 93985 or 93986 and is covered when medically necessary for surgical planning.
- Subsequent autogenous access mapping may be billed with CPT codes 93970 or 93971 when clinically indicated.
