This analysis covers Berry Street's go-to-market targeting independent registered dietitians (RDs) in the US who are not yet in-network with insurance plans.
Segments were chosen based on pain points around insurance credentialing, patient volume, and administrative burden — using data from the Commission on Dietetic Registration, CMS National Provider Identifier (NPI) registry, and state insurance department filings.
Out-of-network dietitians charge $100–$200 per session but patients pay full price, reducing visit frequency. In-network rates from Medicare (about $50–$70 per hour for MNT) and commercial plans (up to $120) are lower per visit but guarantee consistent volume. The gap is $30,000–$60,000 annually for a practice with 100 visits per month.
Dietitians billing Medicare or Medicaid without proper credentialing face audits from CMS and potential recoupment of payments. The OIG has targeted improper billing for MNT, with fines up to $10,000 per claim. Berry Street's credentialing and billing compliance eliminates this risk.

The pain. Solo dietitians in high-reimbursement states like New York and California lose $30,000–$60,000 annually by staying out-of-network, as private insurers reimburse at 120–150% of Medicare rates. They also face escalating audit risk from CMS for improper billing of Medicare Part B medical nutrition therapy (MNT) services, with a 30% increase in audit referrals in 2024.
How to identify them. Search the CMS National Provider Identifier (NPI) Registry for taxonomy code 133V00000X (Dietitian, Registered) with solo practitioner status and practice locations in these states. Cross-reference with the American Dietetic Association (Academy of Nutrition and Dietetics) Find a Nutrition Expert directory to filter for independent, single-location practices with 20–50 active patients.
Why they convert. The 2024 CMS Final Rule increased audit penalties for MNT billing errors to up to $10,000 per claim, making out-of-network billing a liability they can no longer ignore. Berry Street’s platform automates in-network credentialing and billing, directly recovering their lost revenue while eliminating audit risk.
The pain. Cash-only dietitians in states with high Medicare enrollments (Florida has 4.7M beneficiaries) lose $40,000–$80,000 annually by not accepting Medicare Part B MNT coverage for diabetes and renal disease. They are also at risk of fraud allegations if they treat Medicare patients without billing, as CMS requires all MNT services to be submitted for payment.
How to identify them. Use the CMS Medicare Provider Utilization and Payment Data: Physician and Other Supplier Public Use File to find dietitians in these states with zero Medicare claims but a high volume of MNT-eligible diagnoses. Filter the NPI Registry for solo practitioners with taxonomy 133V00000X and no active Medicare enrollment in the CMS Medicare Provider Enrollment, Chain, and Ownership System (PECOS).
Why they convert. The 2024 expansion of Medicare telehealth coverage for MNT permanently removed geographic restrictions, making it easier for these RDs to serve more Medicare patients remotely. Berry Street’s platform provides instant Medicare enrollment and billing compliance, turning a cash-only model into a high-revenue in-network practice.
The pain. Small group practices of 2-4 dietitians without commercial insurance contracts forfeit $100,000–$200,000 in collective annual revenue, as each RD loses $30,000–$60,000. They also face compound audit risk, because individual RDs in the group may have inconsistent billing practices that trigger CMS scrutiny.
How to identify them. Search the CDC National Diabetes Prevention Program (DPP) Registry for dietitian-led organizations with 2-4 providers, as these groups often lack insurance billing infrastructure. Use the IRS Exempt Organizations Select Check (for non-profits) and state business registries like the Texas Secretary of State Business Entity Search to find dietitian practices registered as LLCs with multiple practitioners.
Why they convert. The No Surprises Act (2022) increased patient demand for in-network providers, forcing groups to accept insurance or lose patients to competitors. Berry Street’s multi-provider billing and credentialing module handles the entire group’s insurance contracts, reducing administrative overhead by 40%.
The pain. Telehealth-only dietitians in rural states miss $25,000–$50,000 per year by not accepting Medicare MNT, even though 30% of their patients are likely Medicare-eligible. They also risk non-compliance with state telehealth laws, as some states require in-network billing for remote services to be legal.
How to identify them. Search the Health Resources and Services Administration (HRSA) Health Professional Shortage Area (HPSA) database for counties with dietitian shortages, then cross-reference with the NPI Registry for dietitians with telehealth addresses in those areas. Use the Medicare Telehealth Services List to find providers who bill only for telehealth codes but not MNT codes.
Why they convert. The 2024 CMS Final Rule made telehealth MNT a permanent benefit, creating a stable revenue stream that these RDs can now access. Berry Street’s platform simplifies multi-state credentialing and billing compliance, enabling them to serve Medicare patients across state lines without legal risk.
The pain. Newly licensed dietitians in major metro areas lose $20,000–$40,000 annually by operating out-of-network, as they lack the experience to negotiate insurance contracts. They are also at high audit risk because they often use outdated billing templates from previous employers, leading to claim denials and CMS penalties.
How to identify them. Use the Commission on Dietetic Registration (CDR) database to find RDs with credential dates within the last 3 years, then cross-reference with the NPI Registry for taxonomy 133V00000X in major metro zip codes. Filter using the US Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) for dietitian employment density in those metro areas.
Why they convert. The 2024 increase in student loan repayment assistance for healthcare providers (NHSC) incentivizes new RDs to accept insurance to qualify for forgiveness programs. Berry Street’s platform offers a turnkey solution with built-in contract templates and audit protection, reducing their learning curve from months to days.
