Credentialing by state

Insurance credentialing and payer enrollment in Michigan

Getting a provider in-network in Michigan means three separate enrollments that share one file: Medicare through PECOS and WPS Government Health Administrators, Michigan Medicaid through CHAMPS, the Community Health Automated Medicaid Processing System, and each commercial plan you want, starting with Blue Cross Blue Shield of Michigan. Provider Enrollment Credentialing Services handles all three for physicians, nurse practitioners, physician assistants, therapists and group practices in Detroit, Grand Rapids and Ann Arbor and everywhere else in the state, at flat per-service prices, followed up regularly until approval.

Medicare in Michigan

Medicare enrollment is national, but the review happens at the Medicare Administrative Contractor for your jurisdiction. For Michigan that is WPS Government Health Administrators, jurisdiction J8. Individual practitioners file the CMS-855I in PECOS, groups file the 855B and each clinician reassigns benefits with the 855R, and EFT is set up with the 588. WPS Government Health Administrators typically processes a clean application in 30 to 60 days and Medicare allows billing back to the effective date, which is why Medicare goes first: it is the one enrollment that pays for the waiting time. Development letters give you 30 days to respond, and an unanswered letter is the most common reason a Michigan application is returned.

Michigan Medicaid

Michigan Medicaid is administered by the Michigan Department of Health and Human Services. Provider enrollment is filed through CHAMPS, the Community Health Automated Medicaid Processing System. Every enrollment is screened at a federal risk level: limited-risk types such as physicians, nurse practitioners and most therapists get a license and database check; moderate and high-risk types, which include many agencies and suppliers, add a site visit and in some cases fingerprint-based background checks for owners. Most Michigan Medicaid members are in managed-care plans, and each MCO credentials and contracts separately after the state enrollment is active, so a practice that wants Medicaid patients usually needs the state enrollment plus two to four MCO applications. Revalidation is required at least every five years.

Commercial plans in Michigan

The Blue Cross Blue Shield licensee for Michigan is Blue Cross Blue Shield of Michigan, and for most practices it is the first commercial application because it carries the largest share of employer-sponsored members in the state. Aetna, Cigna, UnitedHealthcare and Humana operate statewide and take applications through Availity or their own provider portals, verifying credentials against your CAQH profile. Behavioral health clinicians apply to the plans' behavioral arms, Optum Behavioral Health, Evernorth and Carelon, rather than the medical networks. Every commercial application is $200 per provider and runs 90 to 120 days; the contract's effective date is set when the plan countersigns, not when you submit.

The order that works

  1. NPI, Tax ID and, for groups, the Type 2 NPI and group W-9, all matching your legal name exactly.
  2. CAQH profile built and attested, with the Michigan license, DEA, malpractice certificate and five-year work history uploaded.
  3. Medicare through PECOS and WPS Government Health Administrators, then Michigan Medicaid through CHAMPS, the Community Health Automated Medicaid Processing System.
  4. Blue Cross Blue Shield of Michigan and the national plans in the same week, so the 90 to 120 day clocks run in parallel.
  5. Regular follow-up with every payer, effective dates recorded, and the maintenance calendar started for re-attestations, license expirations and revalidation.

Questions Michigan practices ask

How long does credentialing take in Michigan?

Plan for 90 to 120 days per payer from a complete application. Medicare through WPS Government Health Administrators is usually the fastest at 30 to 60 days and allows retroactive billing to the effective date. Michigan Medicaid enrollment through CHAMPS, the Community Health Automated Medicaid Processing System typically runs 60 to 120 days depending on risk level and whether a site visit or fingerprinting applies. Commercial plans such as Blue Cross Blue Shield of Michigan run 90 to 120 days and set the effective date at contract countersignature.

Do I need to enroll in Michigan Medicaid before joining its managed-care plans?

Yes. Michigan delivers most Medicaid benefits through managed-care organizations, and federal rules require every MCO network provider to be enrolled with the state program first. The state enrollment through CHAMPS, the Community Health Automated Medicaid Processing System comes first; each MCO application follows as its own commercial-style credentialing.
