Three ways to verify Medicaid Maryland coverage

  1. Payer portal — free, but one patient at a time and 10–15 minutes each with logins.
  2. Phone (IVR) — hold times vary; no written record for the chart.
The third way

Automated 270/271 check

Full benefit detail in seconds, batched for your whole schedule — not one patient at a time.

From $0.50 per check, pay-as-you-go. A one-time enrollment comes first.
