Medicaid maternity rules, state by state

Medicaid covers a large share of births in the US, and no two state programs bill maternity the same way. Some pay a global package. Some refuse it entirely. We publish the rules for each state we bill into.

Three ways to reach the OB/GYN desk

Most practices start with the free audit. But if you just have a question about a code or a denial, ask it — you don't need the form.

What happens after you submit
  1. An AAPC-certified biller and coder reviews it — not a sales rep
  2. You hear back within one business day
  3. No contract, no obligation, nothing to cancel

Let's Get in Touch

Please fill up the form, one of our AAPC certified medical biller and coder will reach out to you.
