Know what you’ll owe — before you go.

The lab hands you a pad and says “sign here, you might owe money.” ClaraCover tells you what Medicare actually covers, what the lab really charges, and what to ask — in plain English, free.

No account. No personal information. Ever.

The $366 signature

It started at a Quest counter in Indiana. My 79-year-old mother — on Medicare, on a fixed income — was asked to sign a pad agreeing to pay “whatever Medicare doesn’t.” Nobody could tell us what that meant. Not the lab. Not the doctor’s office. Not the hour-long hold with Medicare.

So I did the research myself. The pad price for her vitamin D test? $366. The exact same test, bought directly from Quest’s own consumer site? $59. Whether Medicare would pay at all came down to one diagnosis code on the doctor’s order — a published rule anyone could look up, if they knew where.

By the end, I’d saved her $600 across three tests. ClaraCover exists so you don’t need a daughter with a spreadsheet habit to get the same answer. — Darlene, founder

How it works

  1. Find your test.

    Search by name or the 5-digit CPT code printed on your doctor’s order.

  2. See the real numbers.

    Whether Medicare covers it (and for which diagnoses), what Medicare pays, and what the test costs to buy directly if it’s not covered.

  3. Know what to ask.

    Before you sign anything: how to get the price in writing, and what to discuss with your doctor.
