Arizona Medicaid Provider Enrollment and Credentialing: AHCCCS APEP, the Complete Care Plans, Noridian Medicare and Commercial Insurers

Every row below is filed separately and runs on its own clock. Numbers appear only where the agency, policy or statute publishes one.

Physicians in Arizona are licensed by the Arizona Medical Board (azmd.gov) or, for DOs, the Arizona Board of Osteopathic Examiners in Medicine and Surgery (azdo.gov). Both sites were behind a bot check when we updated this page, so look up license details there directly.

AHCCCS requires every provider type to apply in APEP, for new applications, revalidations and changes alike, and accepts a paper form only when the provider explains extenuating circumstances (AHCCCS Provider Enrollment FAQ). The sequence from AHCCCS's own What to Expect guide (revised December 2023):

1. Register a user. Use the User Registration button on the APEP page. Each person needs their own single sign-on with a unique username without spaces or special characters, and an account locks after five failed log-in attempts (Provider Services unlocks it).
2. Choose the enrollment type (see the next section) and work through each step. Every step must show Complete before the application can be submitted; an incomplete step means something required is still missing.
3. Upload documents. The upload step usually wants one document of each listed type. Board-certified provider types enter certificate details and upload proof.
4. Sign the Provider Participation Agreement. AHCCCS publishes separate agreements for providers (PEP-202.8), group billers (PEP-202.9) and referring, ordering, prescribing and attending (ROPA) providers (PEP-202.2).
5. Complete what your provider type requires: the enrollment fee (not for individuals), a site visit for moderate- and high-risk types, and fingerprinting for high-risk types only.
6. Submit. A started application can be resumed for 30 days from its start date, provided Step 1 is marked Complete, so do not open the application until the documents are in hand.

AHCCCS also publishes an APEP Data Entry Guide (PEP-202.1DA) on its APEP page for collecting the answers before you start; it is a worksheet, not an application.

AHCCCS has six application enrollment types: Individual, FAO (Facility, Agency, Organization), Group Biller, Atypical Individual, Atypical FAO, and Contractor/MCO. For a physician practice the choice is usually between two set-ups:

• Individual Sole Proprietor: the provider bills under their own tax ID.
• Group Biller plus rendering individuals: to bill under the practice's tax ID, the business registers as a Group Biller and every servicing provider files a separate individual enrollment. A rendering provider does not bill AHCCCS directly; claims go out under the group.

Atypical providers, those who do not furnish health care as HIPAA defines it, do not need an NPI. Out-of-state providers who need to treat one member file a "One-Time Enrollment for Single Case," which is limited to 180 days, requires a claim showing the earliest date of service, and is open only to providers already enrolled in Medicare or their home state's Medicaid program.

The AHCCCS document list is short: the NPI, a W-9 signed within the last 12 months, current licenses or certifications, any provider-type form (a Group Biller Roster, for example), and supporting documents listed in the Provider Enrollment Screening Glossary (PEP-903).

The rule that trips applications is about ownership. AHCCCS says ownership disclosures "must match the records for the Arizona Corporation Commission, the Arizona Department of Health Services, and the National Plan & Provider Enumeration System," and that inaccurate disclosures may cause a denial or delay. If one of those records is wrong, AHCCCS wants it corrected, and you may upload the modification request with the application as proof. A practice that changed its LLC members or its NPPES authorized official without updating all three records is the classic delay.

AHCCCS's published standard is that it "generally processes Provider Enrollment applications within 60 days of submission." That is an agency statement, not a statutory deadline, and it starts at submission, so the 30-day resume limit and any request for more information sit outside it.

Expedited review. You can request it through the AHCCCS Solutions Center. AHCCCS's examples are an emergent member need (such as a transplant), a member placement or relocation, and a Department of Child Safety foster parent. The request needs the provider name, NPI, TIN, APEP application number and the reason.

Effective date. Enrollment is generally effective on the approval date, and AHCCCS's FAQ says retroactive approval is generally not available. A retroactive date can be requested with documentation and is reviewed case by case; AHCCCS's examples include a required new application after a change of ownership or provider type, and a physician serving members at a health plan's request. A request without documentation is denied. The practical rule: do not see AHCCCS members before approval unless one of those exceptions clearly applies.

AHCCCS screens by the federal risk levels in 42 CFR 455.450: limited, moderate (adds a site visit) and high (adds a fingerprint-based criminal background check, or FCBC). The level for each provider type is in the Provider Enrollment Screening Glossary. Employees who do not meet the FCBC criteria do not need it.

Arizona has one substitution most states do not: a non-expired Arizona Department of Public Safety fingerprint clearance card, together with a valid driver's license or U.S. passport, can take the place of the FCBC. Clearance cards from other states, FBI background checks and employer background checks do not count.

The enrollment fee for calendar year 2026 is $750, effective January 1 through December 31, 2026, and is adjusted each year to match Medicare. AHCCCS says non-institutional providers, including practitioners, dentists and group billers, do not pay it, consistent with 42 CFR 455.460. AHCCCS may refund the fee if it could not approve an application because of a temporary moratorium on that provider type.

Enrollment with AHCCCS gives you an ID; it does not put you in a health plan's network. AHCCCS's available health plans page lists six AHCCCS Complete Care (ACC) plans and where each operates:

(AHCCCS lists three Pinal County ZIP codes, 85542, 85192 and 85550, separately. The same page lists ALTCS plans, the ACC-RBHA plans, the DCS Comprehensive Health Plan and the American Indian Health Program.)

Arizona's plans do not each invent their own rules. AMPM Policy 950 (effective October 1, 2026) applies to the ACC, ACC-RBHA, ALTCS E/PD, DCS CHP and DES DDD contractors and sets the timelines:

• A "Completed Application" is a CAQH application. It must be signed and dated with a current attestation, a current certificate of insurance, a current DEA registration where applicable, a five-year work history (any gap over six months explained in writing) and the completed questionnaire.
• Initial credentialing decision within 60 days; the approved provider loaded into the claims system within 30 days of committee approval, with an effective date no later than the committee approval date or the contract effective date, whichever is later.
• Temporary/provisional credentialing decision within 14 calendar days. It is mandatory, even without a request, for providers in FQHCs, FQHC look-alikes and rural health clinics, hospital-employed physicians where appropriate, providers needed in medically underserved areas, providers joining a contracted oral health group, covering providers, and SAMHSA-certified opioid treatment programs. No one may stay provisional longer than 60 calendar days.
• Notice within 10 days of the committee's decision, and recredentialing at least every three years.
• Concurrent with enrollment. A plan may credential you during your AHCCCS enrollment but must confirm the enrollment before finalizing the Medicaid contract.

The payment rule worth knowing: Policy 950 requires a plan to pay providers who are enrolled with AHCCCS for covered services delivered during credentialing, on or after the date of the Completed Application, and lets the plan recoup that money if the committee later does not approve the provider. That makes the date your CAQH-based application is complete the date to document.

To check AHCCCS application status, log in to APEP. In Process means the application can still be edited; In Review means it has been submitted and is waiting for Provider Enrollment. If something needs fixing during review, use Pull Back on the Enroll Provider page when it is offered, or open an inquiry in the AHCCCS Solutions Center. Only the Domain Administrator, the user who submitted the first application, can give other users access to the provider's domain; Provider Services at (602) 417-7670 can tell you who that is.

After approval AHCCCS expects every change to be reported in APEP: service, correspondence and pay-to addresses, TIN or NPI changes, billing associations, license types or dates, and changes in ownership or managing employees.

• Revalidation every four years to keep billing privileges, with the same screening as the original application; AHCCCS may ask for off-cycle revalidation. The federal floor in 42 CFR 455.414 is five years, so Arizona is stricter.
• Change of ownership must be reported no later than 35 days after the change. A new TIN means reporting the CHOW, ending the prior AHCCCS ID and filing a new application with a new participation agreement.
• A license that lapses and causes termination requires a brand-new APEP application.

Arizona sets a hard clock for commercial plans in A.R.S. 20-3453. A health insurer must conclude credentialing within 60 calendar days of receiving a complete credentialing application, load the provider into its billing system within 30 calendar days, and send written or electronic notice of approval or denial within 7 calendar days after credentialing ends. The definitions in A.R.S. 20-3451 cover disability insurers, health care services organizations and service corporations, and require a "complete" application to include all information and supporting documents and to run through the insurer's credentialing system.

One exception: when a provider works at a licensed health care facility with a delegated credentialing agreement, the 60-day timeline does not apply to the insurer, but loading must happen within 10 calendar days of receiving the roster of changes.

Most commercial applications start from CAQH ProView, and CAQH asks providers to re-attest every 120 days (CAQH quick reference). Because AMPM 950 also defines a Completed Application by a current CAQH attestation, one lapsed attestation stalls the Medicaid plans and the commercial insurers together. See CAQH explained, and the payer-by-payer credentialing hub for the national plans.

Arizona's Medicare Administrative Contractor is Noridian Healthcare Solutions for Jurisdiction F, which Noridian's enrollment contact page lists as Alaska, Arizona, Idaho, Montana, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming. Its provider contact center page routes provider enrollment to 877-908-8431, option 3, Monday through Friday, 8 a.m. to 6 p.m. Central (Central time, one or two hours ahead of Arizona depending on the season). You file the CMS-855I or CMS-855B in PECOS; our Medicare provider enrollment guide explains the forms.

The CMS Program Integrity Manual, chapter 10 holds Noridian to the national processing table: an online application without a site visit, development request or fingerprinting is due 95% within 15 calendar days and all within 50. Under 42 CFR 424.521 physicians and nonphysician practitioners can bill Medicare retroactively for up to 30 days before the effective date (90 after a Presidentially declared disaster), which is more room than AHCCCS's approval-date rule allows.

Railroad Retirement Board beneficiaries' Part B claims are handled by Palmetto GBA, not Noridian. Once Noridian approves you, request a Railroad Medicare PTAN through Palmetto's PTAN Lookup and Request Tool; Palmetto builds the file from your Part B enrollment and asks you to allow up to 30 days.

The Arizona files that slow down usually do so because a record somewhere disagrees with the application, not because the agency is slow. What we see most:

• Ownership records out of sync. The Corporation Commission, ADHS and NPPES must all match the APEP disclosure; an old member or officer on one of them is enough for a delay or denial.
• A W-9 older than 12 months. AHCCCS wants one signed within the last year.
• An application that times out. A started APEP application can only be resumed for 30 days.
• Group Biller without the individuals. Enrolling the business but not each rendering provider leaves claims with no valid servicing provider.
• Seeing members before approval. AHCCCS enrollment is effective on the approval date, and retroactive dates are the exception.
• An expired CAQH attestation, which voids the Completed Application that AMPM 950 and the commercial insurers both rely on.
• A missed four-year revalidation or an unreported change of ownership past 35 days.
• No Railroad PTAN, discovered when the first railroad retiree's claim rejects.

Our process is built for exactly this: we compare every field across APEP, NPPES, the license, the Corporation Commission record and CAQH before anything is submitted, and then follow up with each payer weekly, logging who we spoke to, the date and the reference number.

For an Arizona physician practice: individual and group NPIs with current NPPES data, a W-9 signed within the last 12 months, the IRS letter with the legal name and tax ID, the Arizona license and its dates, DEA registration, board certification if any, malpractice certificate, five years of work history with any gaps explained, ownership and managing-employee details that match the Corporation Commission and ADHS, a DPS fingerprint clearance card if your provider type is high risk, practice locations, and a current CAQH profile. The full list, with secure upload instructions, is on what we need from you to start credentialing.

Credentialing, enrollment and contracting are three different approvals; our page on what provider credentialing is explains which one lets you bill. The national rules behind every state's program are on Medicaid provider enrollment, and other state guides cover Florida and Kentucky.

ClaimCarePro handles AHCCCS enrollment in APEP (individual and Group Biller), credentialing with the AHCCCS Complete Care plans, Medicare with Noridian, the Railroad Medicare PTAN, CAQH and the commercial insurers as one checked file, with weekly, logged follow-up on every payer. Flat pricing: $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).

Not found, and therefore not stated: a statutory deadline for AHCCCS enrollment itself (the 60 days is AHCCCS's published processing statement), how far back a retroactive AHCCCS effective date can reach, any ACC plan's own published credentialing timeline beyond Policy 950, and Noridian-specific processing figures beyond the CMS standard. The AHCCCS fingerprint page returned "not found" on the day we checked.
