MO HealthNet Provider Enrollment and Credentialing: MMAC, eMOMED, the Managed Care Plans and WPS J5 Medicare

A Missouri practice usually needs every row below, and each one is filed and approved separately. The timing column repeats only what the agency, contractor or plan has written down.

Physicians, physician assistants and several other professions are licensed by the Missouri Board of Registration for the Healing Arts, whose licensee search is the primary source MMAC and every plan check against. Confirm your own record there before you type a license number into any application.

MMAC's Provider Enrollment page describes its Provider Enrollment Unit as the office that handles new enrollment, maintains the records and answers enrollment questions for all MO HealthNet provider types, and the one that decides when a provider number is issued or updated. Enrollment runs under 13 CSR 65-2 and 13 CSR 70-3.020. Because the MO HealthNet Provider Enrollment Guide (announced August 2, 2024) exists precisely because "each of the over 60 provider types have different enrollment requirements," the sequence below is the common spine, not a substitute for your provider type's own list.

1. Confirm you can apply online. MMAC's New Providers page says only "select provider types" enroll electronically. Everyone else requests an application package by emailing MMAC.ProviderEnrollment@dss.mo.gov. 13 CSR 65-2.020(2)(A) also requires every applying provider to have a valid email address.
2. Open the Provider Enrollment Application on eMOMED in a current version of Edge, Chrome or Firefox, read the Provider Enrollment Information at the top, and accept. Field-by-field instructions sit on the bottom bar of each screen and a HELP link ends each part.
3. Save as you go. eMOMED issues a PIN tied to your NPI, email and SSN or EIN so a partial application can be retrieved, and the same PIN retrieves an application after it is finalized and submitted. Print and keep every page; MMAC tells providers to.
4. Name a real contact on Part 2. The contact name and email entered there is who receives MMAC's questions about the application.
5. Upload or attach only what your provider type requires, listed under Requirements for Each Provider Type. The forms page carries the Business Organizational Structure form (BOS 2024 v2.1) and its guide, the paper EFT form and the attestations some types need (MMAC forms).
6. Sign the Title XIX participation agreement and fax the signature page with the required attachments to (573) 634-3105. A wet signature or an electronic one from DocuSign, AdobeSign or HelloSign is accepted. The next section covers the fax rules, because they are where Missouri applications die.
7. Register the people who will use eMOMED afterward. eMOMED requires multi-factor authentication effective August 16, 2026 (SMS, email or an authenticator app) and says each individual user should have an account identified by their own SSN.

After approval, MMAC's rule is that the number it issues is used for all MO HealthNet transactions; if separate numbers were issued for different locations or practices, the right one must go on each claim. A technical or faxing problem goes to the Help Desk at 573-635-3559; an application question goes to MMAC.ProviderEnrollment@dss.mo.gov or 833-818-1183.

Missouri is unusual in that the application is fully online but the agreement is not. The eMOMED enrollment home sets out the transmission rules, and each one is a denial if missed:

• Fax only the signed provider agreement signature page and the required attachments. Do not fax the application itself.
• The signature page and the attachments must be on separate pages and sent in one transmission, or the application is denied.
• Pages must not be shrunk or minimized, and must be upright.
• Send one signature page and its attachments per transmission. Two providers' pages in one fax is two problems.
• "An altered agreement is automatically denied." A correction means a new online application; additional information may go by letter with the signed page.

Pair those with MMAC's queue rules: an application returned for more information is not given priority, and an online application denied for improper submission or missing information must be resubmitted and starts over. The ClaimCarePro intake list for a Missouri file, and how to send it securely, is on what we need from you to start credentialing.

Missouri enrolls the business and the clinician separately. UnitedHealthcare's Missouri provider page, which points its own applicants at the state process, names the two tracks: individual providers use the Missouri HealthNet Individual Providers Application and organizations use the Large Provider Organization Application (UHC Community Plan of Missouri). An organization's application carries the Business Organizational Structure form, and 13 CSR 65-2.020(3) requires the ownership and control disclosures on it to be kept current within 30 days of any change, with deactivation, denial or termination among the consequences of a late or missing disclosure. Which NPI goes on which application is covered on our NPI Type 1 vs Type 2 page.

A third track is easy to miss. MMAC's OPR page says any provider who orders, prescribes or refers for MO HealthNet participants must be enrolled even if they do not accept Medicaid, because a claim that depends on an order or referral is denied when the ordering provider has no active enrollment record; remittances flag it with code N613. OPR enrollment needs three documents, the OPR Questionnaire, the OPR Enrollment Application and the Title XIX Participation Agreement, and "failure to submit all listed documents will result in an automatic rejection." An OPR-only enrollee cannot submit claims; a provider already enrolled with MO HealthNet does not enroll again as OPR but must stay active.

Federal rules require every state Medicaid program to screen providers at a limited, moderate or high risk level (42 CFR 455.450), and Missouri codifies its version in 13 CSR 65-2.020(10). MMAC's risk category page describes the layers: limited risk means verification of licensure and certification, checks of the federal exclusion and death databases, NPPES and the National Sex Offender Public Website, and possible pre-approval visits; moderate adds pre-acceptance site visits and unannounced post-enrollment visits; high adds fingerprint-based criminal background checks, including every person with a 5% or greater ownership interest in an institutional provider. The regulation places physicians, non-physician practitioners, hospitals, pharmacies and FQHCs at limited risk, ambulance suppliers, hospice organizations and personal care providers at moderate, and newly enrolling or reenrolling home health agencies and DMEPOS suppliers at high (13 CSR 65-2.020(10)(D)). A provider type not listed is screened as moderate, and a provider fitting more than one level gets the highest. MMAC must move a provider to high risk after a payment suspension for a credible allegation of fraud, an existing overpayment, or an exclusion within the previous 10 years.

Site visits have run for moderate and high risk providers since July 1, 2015; a provider who had one through Medicare or another state Medicaid agency in the last two years does not need another before enrollment, and for an out-of-state applicant MMAC asks the home state's enrollment unit to conduct it (MMAC Site Visits). Fingerprints for high risk providers and their 5% owners are taken through the Missouri Automated Criminal History Site and the state's vendor IDEMIA and go to the FBI and the Missouri State Highway Patrol; owners fingerprinted for Medicare or another state within two years are exempt (MMAC Fingerprint Checks). 13 CSR 65-2.030 allows denial when fingerprints are not submitted within 30 days of a CMS or MMAC request.

The application fee. Under 42 CFR 455.460 and 13 CSR 65-2.020(5), MMAC has collected a fee from institutional providers since July 1, 2015, and its fee page says it is "currently set at $750.00." Individual physicians, dentists and other individual practitioners are exempt, as is any provider who paid Medicare or another state within two years. Pay by card or e-check through Global Payments/Collector Solutions (convenience fee applies) or by cashier's check or money order to DSS-MMAC Application Fee; cash and personal or business checks are not accepted. A hardship waiver is requested from CMS, but the fee is paid first and refunded if CMS approves, and the request must reach MMAC before it processes the application. The fee moves yearly with the consumer price index: MMAC's own posts show $569 for 2018, $586 for 2019, $688 for 2023 and $709 for 2024 (MMAC notices).

Effective date. 13 CSR 65-2.020(1)(B) says a provider generally must be enrolled on the date of service, but enrollment may be made effective "up to a maximum of three hundred sixty-five (365) days prior to the actual enrollment date" unless the rules or provider manual allow earlier. That is a wider window than most states, and it is the reason a Missouri claim backlog from a new hire is often recoverable.

Changes. The same rule (section 11) requires changes affecting the enrollment record to be reported within 90 days and changes in ownership or control within 30 days. Adding a practice location or changing contact information is done with the Provider Update Request form (December 2024 version) faxed to (573) 634-3105, not through a new application.

Deficiencies. 13 CSR 65-2.030 lets MMAC deny a provider that did not submit timely and accurate information unless the failure is cured within 30 days of MMAC's notice that it intends to deny. Denial precludes the submission of claims.

Status. There is no tracker. The eMOMED PIN retrieves the application; questions go to MMAC.ProviderEnrollment@dss.mo.gov or 833-818-1183. For eligibility, claims and remittance questions after enrollment, MO HealthNet Provider Communications is 573-751-2896 or toll-free 833-222-7916, option 1 (MHD Providers page). National guidance on status checks is on our Medicaid provider enrollment hub.

13 CSR 65-2.020(4) requires revalidation "at least every five (5) calendar years" from the effective date of the most recently executed provider agreement, with the revalidation application submitted no later than 120 days before that agreement expires. MMAC's 2015 hot tip says it contacts providers approximately 120 days before the due date with instructions (MHD hot tip), and since January 7, 2019 providers and their authorized representatives can read their own due dates on eMOMED and file the revalidation applications that show as due there, with supporting documents (MMAC Revalidating Providers). The Revalidation Unit is 573-751-5238 and MMAC.Revalidation@dss.mo.gov. MMAC also warns against reusing saved copies of old forms; current versions are on its revalidation requirements page, and stale ones cause rejections.

On May 4, 2026 MMAC announced an off-cycle initiative. Phase I, covering adult day care (provider IDs beginning 29), DME suppliers (62), providers without NPIs, providers CMS or MMAC classes as high risk, and clinics with the autism center specialty, had to revalidate before October 1, 2026, with 120-, 90-, 60- and 30-day notices from June 1 and administrative action, including termination, starting October 1. Phase II, covering home health (58), private duty nursing (94), applied behavior analysts (73), hospice (82) and substance abuse (86), has notices from November 1, 2026 and a deadline of March 2, 2027, with action from March 3 (Notice of Off-Cycle Revalidation Initiative). The state's high-risk revalidation FAQ adds the rules that bite: notices go strictly to the email in eMOMED, a provider newly enrolled or revalidated within the last 12 months is excused, extensions are not guaranteed, termination stops all claims payment and requires a new enrollment, and a managed care network provider must still keep its state enrollment current. Plan recredentialing is a separate three-year cycle, covered on our recredentialing page.

Provider Bulletin 49-12 (August 25, 2026) is the clearest statement Missouri has made about the two-step structure: "Active enrollment with Missouri Medicaid Audit and Compliance (MMAC) establishes state eligibility to participate in the MO HealthNet FFS program; however, it does not grant automatic inclusion in any Managed Care health plan." A provider who wants managed care members must submit a separate credentialing application to each plan, which independently verifies qualifications and primary sources against its own standards, then negotiate and execute a participation agreement with that plan. Until both are done you are out of network for that plan's members. Providers serving only fee-for-service members are not required to do any of it (Bulletin 49-12). Managed care covers parents and caretakers with a child under 19, children birth through 18, adults 19 to 64 without a disability and pregnant women; people with disabilities, seniors and the blind stay in fee-for-service (MHD Providers page).

Each plan states the enrollment-first rule in its own words. Healthy Blue's second step is to obtain an active Missouri Medicaid identification number from the Department of Social Services; UnitedHealthcare says "All providers servicing Missouri Medicaid members must be enrolled with Missouri HealthNet." Home State Health takes new contract requests through its Contract Request Form and status questions through an Enrollment/Credentialing Status Request Form at 1-855-694-HOME. An issue a plan cannot resolve goes to the MO HealthNet Division through the Managed Care Provider Resolution Support Request; UnitedHealthcare notes that state appeals and hearing requests now go only through that online form.

Healthy Blue publishes the most detail (Healthy Blue Missouri): update CAQH ProView with your primary specialty and location and a current attestation, hold the Missouri Medicaid ID, submit the online enrollment application on Availity, which pulls the CAQH profile, then watch for notice that a contract is needed, that the specialty is not needed, or that more information is required. It says "the credentialing process typically takes 45 days" from receipt of a completed CAQH application and that being loaded as participating "usually takes between 60 and 90 days"; recredentialing is every three years, a site review must be allowed within 30 days of request, and an approved prior authorization is needed to see members before participation. Questions go to credentialing@healthybluemo.com. UnitedHealthcare routes applications through Onboard Pro with a One Healthcare ID, emails a reference number, and shows status on a dashboard; DataSpring (CAQH) registration is required only where the state or specialty calls for it. Home State Health publishes no day count on the pages we read. More on the profile itself: CAQH explained.

Missouri law backs those clocks for health carriers generally. RSMo 376.1578 (effective August 28, 2020) requires a carrier to send notice of receipt within two working days of a credentialing application and to provide a web portal for status, gives it ten days to request anything missing and two working days to confirm completeness, and requires approval or denial "within sixty days of the date of receipt of the completed application," with exceptions for applications that surface license discipline, clinical-performance privilege actions, substance abuse or malpractice judgments. When the application is approved, the carrier must pay for covered services furnished during the credentialing period on behalf of a contracted entity, provided claims are filed within six months of approval, and the practitioner may not bill the patient. RSMo 354.442.1(15) directs the Department of Commerce and Insurance to develop one standard credentialing form that all health carriers use in managed care plans, meeting NCQA requirements. Whether a given Medicaid plan treats itself as bound by the 60-day clock is a question for that plan; we did not find a MO HealthNet rule adopting it. National plans' steps are on our payer-by-payer credentialing hub.

This matters before you enroll, not after. On June 25, 2026 the MO HealthNet Division announced that "due to budget constraints" it is terminating reimbursement to licensed chiropractors for services to MO HealthNet participants, and ending acupuncture, chiropractic therapy and physical therapy under the Complementary Health and Alternative to Chronic Pain Management program; "services provided after June 30, 2026, will not be covered or reimbursed" (MO HealthNet Coverage Ending for Some Services, bulletins 48-64 and 48-65). UnitedHealthcare's Missouri provider page repeats the chiropractic cutoff for its members. A September 1, 2026 hot tip clarifies that physical therapy remains covered for participants age 0 to 20, those in a pregnant woman or blind category of assistance, and residents of skilled nursing facilities.

For a chiropractic practice, Missouri Medicaid enrollment is therefore an OPR or referral-integrity question, not a revenue line; for a physical therapy practice it depends on who you treat. Our chiropractic and therapy pages describe how we handle the rest of the payer mix: chiropractic credentialing and physical therapy credentialing.

A practice in Kansas City, Lee's Summit or Independence draws patients from both sides of State Line Road, and the two Medicaid programs do not recognize each other. Kansas Medicaid enrollment runs through KMAP and the KanCare plans, Missouri's through MMAC and the three MO HealthNet plans above, and each state wants its own application, its own screening and its own revalidation. The one place the systems talk is the screening shortcut: a moderate or high risk provider who had a site visit through another state Medicaid agency in the last two years does not repeat it for MMAC, fingerprints taken for another state within two years carry over, and an application fee paid to another state within two years is not charged again. A Kansas City group that enrolls in Kansas first can therefore save the Missouri fee and visit, or the reverse. Both programs sit under the same Medicare contractor, WPS Jurisdiction 5, so the PECOS enrollment is done once. Our Kansas Medicaid (KMAP) enrollment guide covers the other side of the line, and the same WPS J5 pairing applies to Nebraska Medicaid enrollment. South of the bootheel, Arkansas Medicaid enrollment runs under a different MAC, Novitas.

Missouri's Medicare Administrative Contractor is Wisconsin Physicians Service Government Health Administrators (WPS GHA) for A/B Jurisdiction 5, which "processes FFS Medicare Part A and Part B claims for Iowa, Kansas, Missouri, and Nebraska" under contract 75FCMC19C0043, awarded September 20, 2019 (CMS, Who are the MACs: J5, page modified July 8, 2026, which also lists an anticipated contract end of August 2026; check that page if a reprocurement changes the name). CMS's provider enrollment contact list gives the Missouri Part B contractor as Wisconsin Physicians Service, 866-518-3285, Provider Enrollment, P.O. Box 8248, Madison, WI 53708-8248, and routes Missouri DMEPOS enrollment to Novitas Solutions as National Provider Enrollment East at 866-520-5193. WPS's own Part B IVR operating guide (May 2026) lists Jurisdiction 5 at 866-518-3285 with representatives Monday through Friday 7:00 am to 5:00 pm Central and the prompt "2 for Provider Enrollment"; Jurisdiction 8 (Indiana and Michigan) is a different number, 866-234-7331, and an enrollment question sent there lands with the wrong team. WPS's Contact Us page (read October 29, 2026; Provider Enrollment entry for the J5 Part B jurisdiction, updated March 17, 2025) lists the enrollment line as (866) 518-3285, 7:00 am to 5:00 pm Central, Monday through Friday.

You file the CMS-855I or CMS-855B in PECOS and WPS processes it against the CMS timeliness standard (online with no site visit or development: 95% within 15 calendar days and all within 50). Under 42 CFR 424.521 physicians and non-physician practitioners may bill for up to 30 days before their effective date when circumstances kept them from enrolling sooner. Forms, PECOS and timelines are on our Medicare provider enrollment page. Railroad Retirement Board beneficiaries' Part B claims go to Palmetto GBA, not WPS: after WPS approves Part B enrollment, request a Railroad Medicare PTAN in Palmetto's PTAN Lookup and Request Tool and allow up to 30 days.

In our experience the delays trace back to the provider's own paperwork far more often than to the agency, and in Missouri the paperwork is literally paper: a fax. What we check before a Missouri file goes in:

• A fax that breaks a transmission rule. The application page in the fax, attachments on the same page as the signature, shrunk or rotated pages, or two providers in one transmission.
• An edited agreement. Any alteration is an automatic denial; the fix is a new online application.
• A provider type that cannot apply online, discovered after the online application is built instead of before.
• A BOS form that disagrees with the Secretary of State or the IRS, or one that leaves out a 5% owner or managing employee.
• The wrong number on the claim. Separate MO HealthNet numbers for separate locations, and a claim sent under the other one.
• An ordering provider who never enrolled as OPR, which denies the billing provider's claim with N613.
• An unmonitored eMOMED email. Revalidation notices go only there, and a missed one ends in termination and a fresh enrollment.
• A CAQH profile without Missouri selected, unattested or not shared with the plan, which stops Healthy Blue's 45-day clock from starting.
• Treating MMAC approval as network status. Bulletin 49-12's point: no plan contract, no in-network claims.

Our process is built around those failure points: one checked file compared field by field across eMOMED, NPPES, the Healing Arts board, the Secretary of State and CAQH before anything is signed, then follow-up with every payer each week, with the representative's name, the date and the reference number logged.

Have these ready and current: the individual NPI and, for any LLC or corporation, the organization's Type 2 NPI (with NPPES addresses matching the practice); the IRS letter showing the legal name and EIN; the Missouri professional license, verified on the board's search; DEA and CLIA where they apply; malpractice coverage; a completed Business Organizational Structure form naming every 5%-or-more owner, officer and managing employee; a voided check or bank letter for EFT; the list of service locations and which one each claim will bill under; a working email for the application contact and a second one for eMOMED notices; a current CAQH profile with Missouri selected and the plans authorized; the Medicare approval letter once WPS issues it; and, for institutional provider types, the $750 fee or proof it was paid elsewhere within two years.

If you are unsure which of these steps actually lets you bill, our explainer on what provider credentialing is separates enrollment, credentialing and contracting. The same process in other states: provider credentialing in Kansas, provider credentialing in Kentucky and provider credentialing in Florida.

ClaimCarePro enrolls providers with MO HealthNet through MMAC and eMOMED and carries the file through Healthy Blue, Home State Health, Show Me Healthy Kids and UnitedHealthcare credentialing, WPS Jurisdiction 5 Medicare, the Railroad Medicare PTAN, revalidation and the commercial plans, with weekly logged follow-up on every payer. Missouri files are billed at our published flat prices: $250 per payer application per provider, CAQH setup $250, re-credentialing $250, maintenance $99 per provider per year, or the new-practice bundle at $1,750 per provider ($1,400 each additional provider on the same group and payers).
