Frequently asked questions
How many OB-GYNs are in Waterloo, IA?
As of September 2026, the federal NPI registry lists 13 OB-GYNs in Waterloo, IA: 5 at 3 practices, clinics and hospitals, and 8 listed individually. 5 of the 11 listings report a hospital affiliation to Medicare.
Which OB-GYNs in Waterloo, IA take Medicaid?
The NPI registry doesn't record which insurance a practice takes, so we can't say which ones do. Call the office, or search your Medicaid plan's provider directory. Our Iowa pregnancy Medicaid page has the income limits and how to apply.
Are these OB-GYNs accepting new patients?
The NPI registry doesn't say whether a practice is taking new patients, so call the office to check, and ask how far along you should be at the first prenatal visit.
Does a hospital affiliation mean the OB-GYN delivers there?
No. It's a hospital the physician reports to Medicare, through privileges or billing. Ask the practice which hospital its doctors deliver at.
Is an OB-GYN the same as a gynecologist?
An OB-GYN is trained in both obstetrics (pregnancy and birth) and gynecology. Some physicians practice gynecology only and don't provide pregnancy care; we leave out physicians whose main specialty in the NPI registry is gynecology only.
What care is listed in Waterloo, IA?
- In this directory, Waterloo, IA has 9 doulas, 1 lactation consultant, 9 midwives, 2 hospitals with labor and delivery, 11 OB-GYNs and 6 pediatricians (NPI registry, September 2026; CMS hospital data, July 2026).
