Does Medicare cover Magnesium blood test?
Yes — Medicare generally covers Magnesium blood test. It is typically an outpatient service under Medicare Part B, with a Medicare-approved amount of about $7. After your annual Part B deductible, you typically owe the 20% coinsurance — roughly $1 — unless a Medicare Advantage or supplemental (Medigap) plan covers it.
General guidance from Medicare’s national rates — your actual coverage and share depend on medical necessity, your plan, and where the service is performed. Confirm with Medicare or your plan.
About these prices

How to save

- Compare several nearby hospitals; prices for the same service can differ severalfold.
- Request a written estimate and the billing code (CPT/DRG) before scheduling.
- Use the Medicare benchmark above to judge whether a quote is reasonable.
