Short answer: Original Medicare covers qualifying ambulatory blood pressure monitoring when it is ordered to diagnose suspected white coat hypertension or masked hypertension. A standard blood pressure cuff purchased for routine home use is not generally covered as ordinary durable medical equipment.
Original Medicare coverage
Ambulatory blood pressure monitoring uses a portable device that records blood pressure over 24 to 48 hours during normal activity and sleep. CMS covers this diagnostic test for eligible patients with documented suspected white coat hypertension or suspected masked hypertension. The recorded results must be interpreted by the treating physician or qualified non-physician practitioner.
A blood pressure monitor may sometimes be supplied through another covered care program. This is different from a general Medicare benefit for buying a personal home cuff.
Eligibility and limits
CMS sets specific office and out-of-office blood pressure criteria for suspected white coat and masked hypertension. The device must meet technical requirements. The patient must receive oral and written instructions, and a test run must be completed in the provider’s office. For patients who meet the national criteria, ambulatory monitoring is covered once per year. Other uses may be subject to local Medicare contractor decisions.
Costs
Ambulatory blood pressure monitoring is a Part B diagnostic service. The Part B deductible and coinsurance may apply. Costs can depend on the provider, setting, and whether the provider accepts assignment. A patient who purchases a routine home cuff may be responsible for the full price.
Medicare Advantage
Medicare Advantage plans must cover the Medicare-covered diagnostic service. A plan may require an in-network provider or prior authorization. Some plans or care-management programs may lend a home monitor as an additional benefit. Check the plan’s current terms.
What to do next
- Ask whether your provider is ordering ambulatory monitoring or recommending a personal home cuff.
- Ask whether the documented readings meet CMS criteria.
- Confirm coverage with Medicare or your plan before the test.
- Ask whether the provider accepts assignment.
Coverage is determined from the claim, the patient’s eligibility, provider status, and applicable Medicare rules. A provider’s recommendation does not guarantee payment. Before a planned service, ask the provider what will be billed and ask Medicare or the plan whether any coverage review is required.
