Nevada Medicaid Provider Enrollment and Credentialing: Provider Flex, Centralized Credentialing, the MCOs and Noridian Medicare

A Nevada 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 are licensed by the Nevada State Board of Medical Examiners, which offers license verification and a licensee lookup (medboard.nv.gov). Provider Flex verifies the license number automatically for physicians (provider type 20) and physician assistants (provider type 77) and only asks for an upload when the automated check fails.

Nevada switched every provider to Provider Flex on July 8, 2025 (Web Announcement 3667), and its Provider Enrollment page says the tool "will be used for most enrollment related tasks." All initial, re-enrollment and change-of-ownership applications go through it, and paper is refused. The sequence:

1. Read MSM Chapter 100 and your checklist first. Nevada recognizes about 68 provider types, each with a two-digit number and a required specialty, and Provider Flex carries an integrated checklist for each one. A provider enrolling under two provider types files two complete applications.
2. Log in to Provider Flex with multifactor authentication, required since August 25, 2025 (Web Announcement 3702).
3. Choose the enrollment type. Individual (biller and performer, or performer only and linked to a group), Group, Ordering/Prescribing/Referring (OPR, for clinicians who only order or refer and never bill), or Urgent/Emergency for out-of-state providers.
4. Enter the business and identity data. Nevada checks the Secretary of State business license (active, the right entity type, and a formation date on or before the effective date you request), the FEIN against IRS records, and the license against the board.
5. Add every service address. A service address cannot be a P.O. box, a gated community or a virtual address, and each additional organizational service address needs its own application. The email tied to the service and mail-to addresses receives revalidation notices and letters, so use one somebody reads.
6. Upload the EFT proof if you will be paid directly (see the documents section for Nevada's strict matching rules).
7. Sign through DocuSign. Since May 2025 (Web Announcement 3632) the provider or owner signs electronically and, as part of signing, uploads a state-issued license front and back and records a liveness video. Associated providers on a group application are excused from the video step.

After approval Nevada Medicaid emails a welcome letter and the completed contract, and enrollment letters can be downloaded from the secure web portal later.

Nevada now runs two separate systems, and older guides that mention the "Online Provider Enrollment (OPE)" tool describe the system Provider Flex replaced. Use this split:

• Provider Flex: new enrollment, a new service location, re-enrollment of a provider whose contract ended, change of ownership, and resuming or checking any of those applications.
• Provider Web Portal: revalidation and change/update applications, both started from the "Revalidate - Update Provider" link on the My Home page, plus claims after you are enrolled.

License renewals can be sent as an update in the PWP or emailed to nv.providerapps@gainwelltechnologies.com with the NPI, provider name and Medicaid ID; Nevada says no other change is accepted by email. Every change to enrollment information is due within 30 calendar days, and that includes adding or removing a member of a group.

Nevada's enrollment booklet (October 19, 2026) lists key documents by enrollment type. For an individual biller and performer: NPI, Social Security number, proof of FEIN if one is used, the Secretary of State business license, the professional license, and a voided check or bank letter. A group adds its Type 2 NPI, FEIN proof, any facility license, and ownership and disclosed-entity information for everyone with 5% or more direct or indirect interest, board members and managing employees. Some provider types also need CLIA or a DEA number, both verified automatically when entered, and the name on a CLIA certificate must match the legal or DBA name.

What returns Nevada applications is rarely a missing page; it is two records that disagree. The booklet's rules:

• License dates. The original issue date must be on or before the effective date requested, and a license that expires within 30 days will not be accepted.
• Voided checks. Pre-printed only; handwritten or temporary checks and deposit slips are refused. The printed name must match the legal or DBA name in the application, and the routing and account numbers must match the EFT page exactly.
• Bank letters must be on the bank's letterhead and cannot be handwritten.
• Medicare match. Where Nevada requires active Medicare enrollment (hospitals, labs, home health, hospice, FQHCs, rural health clinics, ASCs and the other provider types it lists), the 5%-or-more owners and the provider type must match the Medicare enrollment.

The ClaimCarePro intake list for a Nevada file, and how to send it securely, is on what we need from you to start credentialing.

A Nevada group is paid for its clinicians only when the group and every individual are enrolled and each individual is linked. The group's application must name each individual and NPI who will be paid under it, and each of them electronically signs the Associated Providers List. Physician groups enroll under provider types 20, 24, 72, 74 and 77; Nevada lists separate group types for behavioral health, podiatry, dentistry, optometry, psychology, chiropractic, therapy and others, each with a table of which individual types can link to it.

Two Nevada rules catch new practices. An LLC or corporation, including a single-member LLC or an incorporated individual, must obtain a Type 2 NPI and enroll the business as a group, separately from the clinician's individual enrollment. And when an individual links to a group, the group, not the clinician, takes on the tax liability for Nevada Medicaid payments. Our NPI Type 1 vs Type 2 page explains which number goes where.

Nevada treats border practices as primary providers when care inside Nevada is not available. The booklet's catchment table includes Bullhead City, Kingman and Littlefield in Arizona; Bishop, South Lake Tahoe, Truckee, Susanville, Needles and Sacramento ZIP codes in California; Boise, Mountain Home and Twin Falls in Idaho; and Cedar City, St. George, Salt Lake City, Provo, Wendover and other Utah cities. A practice in one of those areas files a full Group or Individual application in Provider Flex, the same as a Las Vegas or Reno office, and cannot use the urgent/emergency route.

A provider elsewhere who treated a Nevada Medicaid member in an urgent or emergency situation files an Urgent/Emergency enrollment instead. It needs proof of Medicaid enrollment in the provider's home state showing the rendering provider's name, NPI and the state Medicaid program, dated within five years of the date of service, plus a letter of intent or claim with the member's Nevada Medicaid ID, dates of service and procedure codes. Nevada excludes many provider types from this route and says all such enrollments are at its discretion.

Federal rules require every state Medicaid program to screen providers at a limited, moderate or high risk level, with site visits at moderate and high and fingerprinting at high (42 CFR 455.450). Nevada's booklet names the provider types whose owners must sign the Nevada Department of Public Safety fingerprint background waiver: types 19, 29, 33, 58 (specialty 205), 63, 64, 65 and 93 (specialty 708), a list that takes in nursing facilities (19), home health agencies (29), DMEPOS suppliers (33) and hospice (64 and 65), for each owner with 5% or more direct or indirect interest, under 42 CFR 455.434. Individual physicians are not on that list.

Nevada also posts enrollment moratoriums: DMEPOS (Web Announcement 3907, April 30, 2026) and home health agencies and hospice (Web Announcement 3940, June 11, 2026). In June 2026 it began a swift revalidation of high-risk providers, with notices going to those selected (Web Announcement 3935).

The federal application fee in 42 CFR 455.460 applies to institutional providers, not to individual physicians or non-physician practitioners. We did not find a Nevada page stating the current amount, so confirm it in Provider Flex if your provider type owes it.

Nevada publishes no statutory or contractual day count for a new fee-for-service enrollment. What its booklet does say: a submitted application enters a review queue; if it is incomplete, Nevada Medicaid emails the contact on the application a Return to Provider (RTP) letter listing the corrections; nothing is processed while information is missing; and once corrections are made, "providers should allow thirty (30) days for administrative processing." An application with information that blocks processing is rejected outright and cannot be acted on further.

Backdating. Enrollment may be made effective up to six months before the submission date. Request it with a letter of justification and a list of every claim in that window, and remember that a backdated effective date does not extend Nevada's timely filing limit.

Status. Provider Flex lets you resume or check an application. Gainwell's contact center is (877) 638-3472, 8 a.m. to 5 p.m. Pacific, Monday through Friday; say "Enrollment" at the prompt. For anything outside Gainwell's lane, the state's Provider Enrollment Unit is at (775) 684-3701 and providerenrollment@nvha.nv.gov (Nevada Medicaid Providers page). National guidance on status checks is on our Medicaid provider enrollment hub.

Nevada Medicaid requires revalidation at least every five years, and every three years for DMEPOS suppliers. The state's Provider Revalidation Report lists each provider's next due date, and reminders go out by email or mail 120, 90, 60 and 20 days before it. You may file up to one year early; anything earlier is returned.

The deadline is strict in a way that surprises practices: the revalidation must be processed and approved, not merely submitted, before the due date, or the contract terminates. Nevada's enrollment page adds that a provider whose revalidation is not processed by the termination date cannot serve fee-for-service or MCO members (Web Announcement 1265), so a lapse cuts off the managed care plans as well. A revalidation updates everything except ownership; a change of ownership goes through Provider Flex.

One more Nevada rule: a provider who voluntarily terminates with Form FA-34 cannot re-enroll for 365 days unless there is an access-to-care issue or a sanction applies. Recredentialing with the plans is a separate cycle, covered next and on our recredentialing page.

Before 2025, a Nevada provider credentialed with each Medicaid plan one at a time. Nevada's Board of Examiners approved a CVO contract with Verisys on March 12, 2024 (Web Announcement 3324), and centralized credentialing went live on February 28, 2025 (Web Announcement 3567). Verisys now performs primary source verification and runs the credentialing committee for every managed care entity, under NCQA standards, CMS guidance and Nevada's rules. The state's credentialing FAQ sets out the steps:

1. Hold an active Nevada Medicaid contract, or have an enrollment application under review. A denied enrollment means denied credentialing.
2. Contact each plan you want to join and ask to contract. The plan notifies Verisys.
3. Individual practitioners keep a complete CAQH profile with Nevada selected, authorize the plans to see it, and update it before any license, certificate or insurance expires, or at least every 120 days. Facilities receive an application from the CVO, which can be returned by secure upload, email, fax or mail.
4. Verisys verifies with primary sources, runs state and federal database checks, and sends results to Nevada Medicaid and each requesting plan. The plan notifies you and finishes the contract.

Timing: the FAQ says credentialing "can take up to 120 calendar days," longer when the application is incomplete, attachments are missing, or a license or insurance policy expires mid-process. Recredentialing is at least every 36 months from the initial credentialing date, with Verisys sending the notice. What it does not do: passing credentialing does not guarantee a plan will take you, credentialing with one plan does not credential you with the others, and you may not see a plan's members until you hold its contract. Status questions go to the plan; documents go to Verisys at 1-855-743-6161. More on the profile itself: CAQH explained.

On January 1, 2026 Nevada moved managed care statewide: rural members were assigned a plan that day, and urban members chose during an October 1 to December 26, 2025 open enrollment (Web Announcement 3753 and its plan sheet, updated October 7, 2025). Which plans you need depends on where your patients live:

Dental is different: urban members get dental benefits through LIBERTY Dental Plan (provider relations 888-700-0643), while rural dental stays fee-for-service. The phone numbers above are the ones Nevada lists on its Provider Credentialing page. A practice in Elko, Ely or Winnemucca therefore credentials with CareSource and SilverSummit; a Henderson practice may need all five.

Centralized verification has not removed every plan-level step. Health Plan of Nevada's Medicaid credentialing page says its applications are reviewed through the centralized process but "should still be submitted directly to UHC HPN Medicaid," lists the NDOI-901 practitioner application (Rev 02.2025), the NDOI-901B facility application and the NDOI-901A addendum, asks for a CAQH number if you have one, and states that incomplete applications are not started and not retained. It also says providers should not see members until the welcome letter arrives.

Those forms come from Nevada insurance law. Under NRS 629.095 the Commissioner of Insurance prescribes one credentialing form, and the Division of Insurance's Bulletin 25-004 (October 13, 2025) reminds every insurer, HMO and managed care organization to use NDOI-901, introducing the 901A addendum and the 901B facility application. NRS 695C.125 bars an HMO from contracting with a provider unless it uses that form. Nevada's credentialing page notes Medicaid applicants may need these Division of Insurance forms as well. We did not find a Nevada statute setting a day limit for commercial credentialing decisions, so none is quoted here; national plans' steps are on our payer-by-payer credentialing hub.

Nevada's Medicare Administrative Contractor is Noridian Healthcare Solutions for Jurisdiction E, the A/B contract covering California, Hawaii, Nevada, American Samoa, Guam and the Northern Mariana Islands (Noridian JE contact page). Some sources point Nevada practices at Noridian's Jurisdiction F; that contract covers Alaska, Arizona, Idaho, Montana, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming, and an enrollment question sent there goes to the wrong team. The JE Part B Provider Contact Center (updated October 6, 2026) takes enrollment calls at 855-609-9960, option 3, Monday through Friday, 6 a.m. to 5 p.m. Pacific.

You file the CMS-855I or CMS-855B in PECOS and Noridian 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 Medicare for up to 30 days before their effective date when circumstances kept them from enrolling sooner. Forms, PECOS and timelines are covered on our Medicare provider enrollment page.

Railroad Retirement Board beneficiaries' Part B claims go to Palmetto GBA, not Noridian. After Noridian approves your Part B enrollment, request a Railroad Medicare PTAN in Palmetto's PTAN Lookup and Request Tool; Palmetto builds the record from your Medicare enrollment and asks you to allow up to 30 days. Nevada Medicaid's booklet adds a Medicare-related point: claims sent to Medicare can cross over to Nevada Medicaid automatically only if the provider or group is enrolled with Nevada Medicaid.

In our experience the delays trace back to the provider's own data far more often than to the agency, and Nevada's automated checks surface those gaps early. What we look for before a Nevada file is submitted:

• A Secretary of State record that does not fit. An inactive business license, the wrong entity type, or a formation date later than the requested effective date.
• Bank proof that fails the match. A starter check, a deposit slip, or a printed name that differs from the legal or DBA name on the application.
• A license close to renewal. Nevada refuses a license expiring within 30 days, and a license or malpractice policy that lapses during CVO verification extends the credentialing clock.
• Addresses that are not service addresses. P.O. boxes and virtual offices are refused, and a second location needs its own application.
• A CAQH profile without Nevada selected, unattested, or not shared with the plans, which leaves Verisys nothing to verify.
• Different NPIs in different places. The NPI type and number used for fee-for-service must be the same one used to credential with the MCOs.
• An unmonitored contact email. RTP letters and revalidation notices go to the address on the application.
• Waiting on the plan that never got asked. Verisys starts only after a plan requests credentialing, so a practice that never contacted CareSource or SilverSummit is not in their queue.

Our process is built around those failure points: one checked file compared field by field across Provider Flex, NPPES, the 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 group's Type 2 NPI (with NPPES addresses matching the practice); the IRS letter showing the legal name and FEIN; the Nevada Secretary of State business license; the Nevada professional license; DEA and CLIA where they apply; malpractice coverage; a pre-printed voided check or a bank letter on letterhead; the names and details of 5%-or-more owners, board members and managing employees; every service location; a current CAQH profile with Nevada selected; and the Medicare approval letter once Noridian issues it.

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 Florida and provider credentialing in Kentucky.

ClaimCarePro enrolls providers with Nevada Medicaid in Provider Flex and carries the file through Verisys credentialing with Anthem, CareSource, Health Plan of Nevada, Molina and SilverSummit, plus Noridian Medicare, the Railroad Medicare PTAN, revalidation and the commercial plans, with weekly logged follow-up on every payer. Nevada 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). Start credentialing now for a secure start link within one business hour, or call (844) 772-8902. What is included is on our provider credentialing services page.
