[Request a Revenue Defense Audit](https://webillhealth.com/revenue-defense-audit/request/) Iowa is revalidating every enrolled Medicaid provider between July 1, 2026 and June 30, 2028, in waves, and a provider that misses its deadline is deactivated and cannot be paid. Iowa Health and Human Services explains the plan on its [Medicaid provider revalidation page](https://hhs.iowa.gov/medicaid/provider-services/provider-enrollment/provider-revalidation). * Revalidation period A statewide revalidation from July 1, 2026 through June 30, 2028, requested by CMS.

[Iowa Medicaid provider revalidation](https://hhs.iowa.gov/medicaid/provider-services/provider-enrollment/provider-revalidation) * Who goes first High risk providers, providers with state issued atypical NPIs, and providers already past due, with all others in the second year. [Iowa Medicaid revalidation strategy, July 1, 2026 to June 30, 2028](https://hhs.iowa.gov/media/18835/download?inline=) * Applications A separate enrollment application is required for each unique Tax ID. [Iowa Medicaid provider enrollment and revalidation training, September 30, 2025](https://hhs.iowa.gov/media/17455/download?inline=) * What we see in practice 45 to 90 days from submission to an active Medicaid ID. ## In the official words > If revalidation is not completed by the stated deadline, the provider’s enrollment will be deactivated until all required information is submitted. [Iowa Health and Human Services](https://hhs.iowa.gov/medicaid/provider-services/provider-enrollment/provider-revalidation) > Claims cannot be paid during any period of deactivation. [Iowa Health and Human Services](https://hhs.iowa.gov/medicaid/provider-services/provider-enrollment/provider-revalidation) ## Iowa is revalidating every enrolled provider by June 2028 In response to a CMS request, Iowa launched a statewide revalidation that runs from July 1, 2026 through June 30, 2028. [Iowa Medicaid provider revalidation](https://hhs.iowa.gov/medicaid/provider-services/provider-enrollment/provider-revalidation) The state sends notices in overlapping waves of about 30 days, starting with high risk providers, then those already past due, and ending with everyone else. [Iowa Medicaid revalidation strategy, July 1, 2026 to June 30, 2028](https://hhs.iowa.gov/media/18835/download?inline=) Each notice arrives by standard USPS mail with the provider’s own deadline, and the provider has 30 business days from the date of the notice to submit all required materials. [Iowa Medicaid provider revalidation](https://hhs.iowa.gov/medicaid/provider-services/provider-enrollment/provider-revalidation) A provider that revalidated within the past 12 months keeps the next date shown on the notice it received then. [Iowa Medicaid provider revalidation FAQ, updated June 2026](https://hhs.iowa.gov/media/18853/download?inline=) The FAQ says revalidation will ask providers to confirm or update ownership information, licensure, accreditation status, service locations and contact information, and some documents may need to be sent again if they expired, changed or are incomplete. [Iowa Medicaid provider revalidation FAQ, updated June 2026](https://hhs.iowa.gov/media/18853/download?inline=) ## How enrollment works, step by step 1. File one application for each Tax ID. A provider that operates under several Tax IDs submits a separate application for each. [Iowa Medicaid provider enrollment and revalidation training, September 30, 2025](https://hhs.iowa.gov/media/17455/download?inline=) 2. File it only once. More than one application for the same Tax ID, individual provider and location counts as a duplicate, and duplicates can be withdrawn. [Iowa Medicaid provider enrollment and revalidation training, September 30, 2025](https://hhs.iowa.gov/media/17455/download?inline=) 3. Use the current form. The revision date is printed in the bottom left corner of the form. [Iowa Medicaid provider enrollment and revalidation training, September 30, 2025](https://hhs.iowa.gov/media/17455/download?inline=) 4. Match the group file. The NPI, taxonomy code and ZIP code in the group linkage boxes must be identical to the group file, and an individual’s provider type must agree with the group’s. [Iowa Medicaid provider enrollment and revalidation training, September 30, 2025](https://hhs.iowa.gov/media/17455/download?inline=) 5. At revalidation, include the Enrollment Renew List, which providers often overlook. [Iowa Medicaid provider enrollment and revalidation training, September 30, 2025](https://hhs.iowa.gov/media/17455/download?inline=) Iowa training from September 2025 says mismatched provider types can bring enrollment delays or rejections [Iowa Medicaid provider enrollment and revalidation training, September 30, 2025](https://hhs.iowa.gov/media/17455/download?inline=), and an application missing requested information automatically recycles in 90 days [Iowa Medicaid provider enrollment and revalidation training, September 30, 2025](https://hhs.iowa.gov/media/17455/download?inline=), so the working range we give an Iowa provider is 45 to 90 days from submission to an active Medicaid ID. ## Who gets an Iowa notice first The first wave goes to providers with state issued atypical NPIs, providers past due for revalidation, and providers whose risk level dropped after enrollment, such as home health, durable medical equipment and hospice. [Iowa Medicaid revalidation strategy, July 1, 2026 to June 30, 2028](https://hhs.iowa.gov/media/18835/download?inline=) The strategy also moves any provider type up the list when a risk indicator appears, including a payment suspension, an overpayment, an OIG exclusion in the past 10 years, or enrollment after a moratorium was lifted. [Iowa Medicaid revalidation strategy, July 1, 2026 to June 30, 2028](https://hhs.iowa.gov/media/18835/download?inline=) Everyone else is in the second year, from July 1, 2027 through June 30, 2028. [Iowa Medicaid revalidation strategy, July 1, 2026 to June 30, 2028](https://hhs.iowa.gov/media/18835/download?inline=) The FAQ says high risk provider types will be contacted earlier and lower risk providers in later phases. [Iowa Medicaid provider revalidation FAQ, updated June 2026](https://hhs.iowa.gov/media/18853/download?inline=) ## Where Iowa enrollments lose money A provider that does not finish by the stated deadline is deactivated until all required information is submitted, and claims cannot be paid during any period of deactivation. [Iowa Medicaid provider revalidation](https://hhs.iowa.gov/medicaid/provider-services/provider-enrollment/provider-revalidation) The FAQ puts it more plainly: claims are denied until the provider is revalidated. [Iowa Medicaid provider revalidation FAQ, updated June 2026](https://hhs.iowa.gov/media/18853/download?inline=) Deactivation also follows when a provider has not started its revalidation by the deadline, or when Iowa receives returned mail and cannot reach the provider by phone or email. [Iowa Medicaid provider revalidation](https://hhs.iowa.gov/medicaid/provider-services/provider-enrollment/provider-revalidation) A deactivated provider may enroll again with a new application. [Iowa Medicaid provider revalidation](https://hhs.iowa.gov/medicaid/provider-services/provider-enrollment/provider-revalidation) The strategy lists automating deactivation for failure to revalidate among its goals.
