1. Procedure Codes for Dietitians

Procedure codes are used to describe the services dietitians provide in patient care. The main codes dietitians work with include the CPT (Current Procedural Terminology) codes and HCPCS (Healthcare Common Procedure Coding System) codes.

• MNT CPT and HCPCS Codes: These codes are used for Medical Nutrition Therapy (MNT) services, such as counseling, assessment, and management of chronic conditions like diabetes, obesity, or hypertension.

  • CPT Code 97802: Initial nutrition assessment and intervention, face-to-face.

  • CPT Code 97803: Reassessment and subsequent intervention, face-to-face.

  • HCPCS Code G0270: MNT services for patients with diabetes, obesity, or renal disease, provided by a registered dietitian.

• Additional Codes Considered by Medicare: Medicare typically recognizes MNT services for specific conditions like diabetes and kidney disease. However, for broader coverage, dietitians may need to understand the full range of codes that include preventive care and follow-up consultations.

  • CPT Code 99213: Follow-up consultation for disease management, used in collaboration with dietitians.

  • HCPCS Code G0108: Diabetes management, used for Medicare claims for MNT services (Limited for recognized Diabetes Self Management Programs).

2. S Codes and G Codes

• S Codes: These codes are used by private payers for specific services not covered by Medicare. S codes are typically used for non-covered or non-reimbursable services, including some dietitian services that do not fall under traditional CPT or HCPCS codes.

• G Codes: These codes are for services that are not included in the standard CPT or HCPCS system but are accepted by Medicare for certain types of treatment or testing.

  • G0270: Used for MNT services for certain chronic conditions.

3. Determining the Units of MNT Codes to Report on Claims (8-Minute Rule)

The 8-minute rule is important for billing purposes. It means that any given code is reimbursed based on the total time spent with a client.

• If the session is 8 to 22 minutes, report 1 unit of the relevant CPT code.

• If the session is 23 to 37 minutes, report 2 units.

• Continue calculating units based on the same principle (for every additional 15 minutes, add 1 unit).

Properly calculating the units for MNT services ensures accurate billing and compliance with payer requirements.

4. Modifiers: Understanding the Impact on Claims

Modifiers are important when submitting claims to indicate specific circumstances or changes in a patient's condition that affect reimbursement.

• GA: Waiver of liability statement issued as per Medicare requirements.

• GZ: Service is non-covered, but the provider is required to report it.

• GY: Item or service is not covered by Medicare.

• GT: Telehealth services.

• 95: Synchronous telemedicine services.

• 33: Preventive services under the Affordable Care Act.

• 93: Telehealth services provided for a specific service type.

5. ICD-10-CM Diagnosis Codes for Dietitians

The ICD-10-CM (International Classification of Diseases, 10th edition, Clinical Modification) codes are used for diagnoses. Understanding these codes helps dietitians document and report conditions effectively.

• Z Codes: These codes are used for patients without a specific diagnosis but who may benefit from preventive care or dietary interventions. These codes also apply to routine check-ups, health screenings, or when a patient is healthy but seeking dietary counseling.

  • Z71.3: Dietary counseling.

  • Z72.4: Inadequate physical activity.

• Healthy Individuals / No Diagnosis: Even without a specific diagnosis, dietitians can use preventive care codes for healthy individuals, including those seeking guidance on nutrition or wellness.

• Preventive Care: Preventive services are increasingly recognized, with specific codes for dietitians providing counseling, health assessments, and lifestyle interventions.
