When maternity billing changes, your health costs change with it — and employers are usually the last to see it coming. Starting January 1, 2027, the way maternity care gets billed is being rebuilt from the ground up. What replaces it will show up in your premiums — or your direct costs if you're self-funded — whether or not your team is ready for it.

Here's what's happening: one global maternity fee is splitting into itemized codes for prenatal, delivery, and postpartum care. CMS's proposed fee schedule shifts value within that new structure — labor and delivery codes could see a 15% bump, while prenatal and postpartum visits lose ground — and none of it is finalized yet. A separate proposal could also let some payers keep billing the old way, meaning two different billing systems could end up running side by side for the same pregnancy.

If you're trying to plan your 2027 renewal, benefits and health spend around a rule that isn't finished being written, you're not alone. Join Maven's Chief Medical Officer and Chief Revenue Officer for an AMA on what's changing, what it means for your costs, and how to get ahead of it.
