Nutrition therapy billing is full of payer-specific rules, referral requirements, and coverage limitations. We cut through the confusion so you can focus on your patients and get paid for the work you do.
Registered Dietitians and Registered Dietitian Nutritionists occupy a unique billing space. Medicare covers Medical Nutrition Therapy (MNT) under Part B for specific diagnoses, but with strict hour limitations, referral requirements, and HCPCS G-code structures that differ from standard CPT billing. Commercial payers each have their own rules on top of that.
Medicare Part B covers MNT for diabetes and renal disease, with specific annual hour limits and diagnosis requirements. Billing outside covered diagnoses or exceeding limits without proper documentation leads to denials.
Medicare MNT uses HCPCS G-codes (G0270, G0271) while many commercial payers prefer CPT codes (97802, 97803, 97804). Submitting the wrong code set to the wrong payer is a fast path to rejections.
Medicare requires a physician referral for MNT services. Without proper documentation of that referral on file, claims can be denied or recouped after the fact.
Not all payers credential RDs independently. Knowing which plans cover RD services, under what conditions, and how to get properly enrolled is critical to actually getting paid.
Arizona's Medicaid program covers nutrition services for certain populations under specific programs. We navigate those coverage rules so eligible services don't go unbilled.
Group nutrition education sessions are billed differently from individual MNT. Using the wrong code, or failing to note group size in documentation, results in underpayment or denial.
| Code | Service | Notes |
|---|---|---|
| G0270 | MNT Initial Assessment (Medicare) | Diabetes & renal disease; requires physician referral |
| G0271 | MNT Follow-Up Session (Medicare) | Per 30 minutes of reassessment/intervention |
| 97802 | MNT Individual, Initial (Commercial) | Per 15 minutes; used by most commercial payers |
| 97803 | MNT Individual, Re-Assessment (Commercial) | Per 15 minutes; follow-up visits |
| 97804 | MNT Group Nutrition Education | Per 30 minutes; group of 2 or more |
| S9470 | Nutritional Counseling (Some Payers) | Payer-specific; not universally accepted |
Code applicability depends on diagnosis, payer, and documentation. This is a reference only.
Getting credentialed as an RD can be an uphill battle with certain payers. We handle the enrollment process for Medicare, AHCCCS, and commercial plans — so you start getting paid faster.
We also manage CAQH profile setup and maintenance, which many payers require as part of the credentialing process.
Coverage for RD services varies significantly by plan. We verify benefits before claims are submitted so there are no surprises on either end.
