Does Medicare cover Clotting time test (PTT)?
Yes — Medicare generally covers Clotting time test (PTT). It is typically an outpatient service under Medicare Part B, with a Medicare-approved amount of about $6. 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
Based on prices published by 2316 US hospitals across 52 states, the typical (median) cash price is $50, versus a chargemaster (list) price around $95, a median insurer-negotiated rate of $14, a Medicare rate of about $6. Most cash prices fall between $13 and $143 — a wide spread, which is exactly why comparing hospitals pays off.
How to save
- Ask each hospital for its cash / self-pay price — for shoppable services it is often far below the list price.
- 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.
- If you are uninsured, ask about financial assistance or prompt-pay discounts.
