[Request a Revenue Defense Audit](https://webillhealth.com/revenue-defense-audit/request/) Wyoming Medicaid pays only providers who are actively enrolled, and it holds claims for 30 days when the contact details on an enrollment record are inaccurate, and denies them if the record is not corrected in that time. The [Wyoming Medicaid CMS 1500 Provider Manual](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf), in its October 1, 2026 version, sets out screening, reenrollment every five years and the claims hold. * Reenrollment Providers complete an enrollment application, a screening and a new Provider Agreement at least every five years, and are told in advance when reenrollment is required.

Claims will be held for 30 days pending an update of the information. [Wyoming Department of Health](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) > Medicaid payment is made only to Providers who are actively enrolled in the Medicaid Program. [Wyoming Department of Health](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) ## Wyoming holds claims when the contact details on file are wrong If the contact information on a provider’s record proves inaccurate, Wyoming Medicaid places the provider on a claims hold, and claims are held for 30 days while the record is updated. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) If the information is updated within the 30 days, the held claims are released for normal processing. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) A claim held for more than 30 days is denied, and the provider has to resubmit once the information is corrected. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) A notice on the Wyoming Medicaid notices page ties enrollment status to the mailing address on a provider’s W9 form. When a 1099 form is returned as undeliverable, Medicaid payments are placed on hold. [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) The notice adds that the provider’s enrollment status is then updated to inactive. [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) It asked providers to verify their mailing address with HHS Tech Group, the enrollment vendor, by December 15, 2025, and to keep it current through the year. [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) That date has passed, so confirm the current status of your record. The same notices say Wyoming Medicaid must be able to reach every provider directly by email and phone. [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) A provider’s enrollment status may be updated to inactive when emails bounce or when emails are directed only to the provider’s vendors. [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) The manual adds that policy updates are distributed by email, and occasionally by postal mail. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) Federal rules set the floor: a state must revalidate every provider at least every five years. [42 CFR 455.414](https://www.ecfr.gov/api/versioner/v1/full/2026-10-29/title-42.xml?part=455§ion=455.414) Wyoming’s manual sets the same cycle and says providers are notified in advance when reenrollment is required to stay active. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) ## How enrollment works, step by step 1. Apply through the enrollment vendor. Providers complete the online enrollment application on the HHS Technology Group website. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) 2. Expect screening. Providers are assigned one of three categorical risk levels under the Affordable Care Act and are required to be screened. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) 3. Pay the application fee only if your type is listed. The manual places the fee on a list of institutional provider types, in state only. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) A provider already enrolled in Medicare, another state’s Medicaid or the Children’s Health Insurance Program (CHIP) pays only one enrollment fee, and the fee is not refundable. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) The fee also applies to reenrollments Medicaid requests after an enrollment goes inactive, for the listed types. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) 4. Sign the Provider Agreement. It is part of enrollment and is repeated at least every five years. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) 5. Wait for the welcome letter. Approval is followed by a welcome letter, and an application that is not approved gets a notice giving the reasons. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) 6. Do not count on a backdated start. Backdating must go through an appeal, with proof of enrollment with Medicare or another state’s Medicaid. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) An earlier effective date takes an appeal, [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) so we quote a new Wyoming provider 45 to 90 days from submission to an active Medicaid ID. ## Who has to enroll in Wyoming, and who does not Ordering, referring and prescribing providers must be enrolled, and so must attending providers. [Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) The manual applies this to in state and out of state providers, even those who do not bill Wyoming Medicaid, except on Medicare crossover claims.

[Wyoming Medicaid CMS 1500 Provider Manual, version of October 1, 2026](https://wyomingmedicaid.com/portal/References/latestproviderfiles/BMS_Acentra%20Health_CMS-1500%20Provider%20Manual_N_2026.10.01_v20.0.pdf) An out of state provider who is not enrolled and treats a Wyoming Medicaid member may choose to enroll and bill Medicaid, or bill the member.

[Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) It says providers cannot opt out of Medicare enrollment because Medicaid is the payer of last resort. [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) It adds that claims for dates of service from January 1, 2024 go to Medicare first and Medicaid second or third.

[Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) An undated notice on the same page said claims from more than 200 providers had been denied, in denials running from October 24, 2021 to the date of that notice, where enrollment status, effective dates, group association or taxonomies on the enrollment record did not match the claim. [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) Those denials carried error 1452, invalid or missing servicing or rendering provider at header, with claim adjustment reason code 16 and remark code N290, a missing, incomplete or invalid rendering provider primary identifier. [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) [Wyoming Medicaid provider notices](https://wyomingmedicaid.com/portal/ProviderWhatsNew) In an undated notice with a January 15, 2025 deadline, Wyoming Medicaid told providers that had not revalidated that their claims would begin to deny with error 5300, billing provider or vendor ID inactive.
