Credentialing by specialty
Insurance credentialing for registered dietitians
Payer enrollment for registered dietitians follows the same sequence as every other provider type, CAQH first, then Medicare and Medicaid, then the commercial plans, but the details that stall applications are specific to the specialty, starting with the taxonomy code (133V00000X) that every payer cross-checks against NPPES. Provider Enrollment Credentialing Services enrolls registered dietitians in every state at flat per-service prices and follows up on each application until approval.
Medicare for registered dietitians
Registered dietitians enroll in Medicare with an 855I to bill medical nutrition therapy for diabetes and kidney disease; other diagnoses are not covered by Original Medicare.
Commercial and Medicaid networks
Commercial coverage for nutrition counseling is broader than Medicare's, and most plans credential RDs directly through CAQH.
What to watch
Telehealth nutrition counseling is widely covered but the place-of-service and modifier rules differ by plan.
The file we build for registered dietitians
- NPPES record checked and corrected first: legal name, taxonomy, practice address. Mismatches here are the most common silent cause of a returned application.
- CAQH profile built or repaired, every section complete, documents uploaded, attested, with each target plan authorized to view it.
- Medicare and Medicaid applications where they apply, filed and tracked to approval with every development letter answered inside its 30-day window.
- Commercial applications submitted the same week so the 90 to 120 day clocks overlap, with closed-panel responses appealed or re-requested on a schedule.
- Effective dates, contract terms and fee schedules recorded, and the maintenance calendar started: CAQH re-attestation every 120 days, license and malpractice expirations, Medicare revalidation.
Pricing for registered dietitians
CAQH $500, Medicare $500, Medicaid $500 per state, each commercial application $200, group onboarding $500 one-time, maintenance $100 per provider per quarter. Every service and price, or start the intake; about 15 minutes, with a reference number to check status any time.
Questions RDs ask
How long does credentialing take for registered dietitians?
Medicare, where it applies, runs 30 to 60 days and allows retroactive billing. Medicaid runs 60 to 120 days depending on the state. Commercial plans run 90 to 120 days each, in parallel, with the effective date set at contract countersignature. A complete file on day one is the only thing that shortens any of them.
Do RDs need CAQH?
Yes for every commercial plan and most Medicaid managed-care plans. The CAQH ProView profile is where plans pull licenses, education, work history and malpractice from, so it is built and attested before the first application goes in.
