CPT® Code 97803

CPT® Code 97803 is used to report individual medical nutrition therapy (MNT) reassessment and intervention, typically provided face-to-face with the patient. The service includes reviewing the patient's progress, reassessing nutritional needs, and modifying the nutrition intervention or treatment plan based on the patient's current condition.

This code is commonly used for follow-up nutrition counseling for patients managing diabetes, obesity, cardiovascular conditions, gastrointestinal disorders, and other conditions where nutrition plays an important role in care.

CPT 97803 is generally reported for each 15 minutes of individual face-to-face time with the patient.

When to Use CPT® 97803

CPT 97803 is appropriate when a qualified provider performs follow-up medical nutrition therapy that includes reassessment and intervention.

Examples:

  • Reviewing a patient's progress after an initial nutrition assessment
  • Adjusting a nutrition plan based on changes in weight, laboratory results, or health status
  • Modifying dietary recommendations for a patient managing diabetes
  • Reassessing nutritional goals during a weight management program
  • Updating an individualized nutrition care plan based on the patient's response to previous interventions

The service should involve meaningful reassessment and intervention rather than simply providing educational materials.

Documentation Requirements

To support CPT 97803 billing, documentation should include:

  • Patient identifiers and date of service
  • Relevant diagnosis or medical indication for MNT
  • Nutrition-related assessment and progress since the previous visit
  • Dietary intake or behavioral information, when relevant
  • Changes in weight, laboratory findings, or other clinical indicators when applicable
  • Nutrition interventions and recommendations provided
  • Updated nutrition goals or treatment plan
  • Total face-to-face time
  • Patient response and follow-up plan
  • Provider credentials and signature

Time-based documentation should clearly support the number of units reported.

Reimbursement and Coding Considerations

  • CPT 97803 is reported per 15 minutes of individual face-to-face MNT reassessment and intervention
  • It is generally used for follow-up services, rather than the initial nutrition assessment
  • Diagnosis coding should support the medical necessity of nutrition therapy
  • Coverage varies by payer, diagnosis, provider credentials, and applicable benefit requirements
  • Some payers may limit the number of covered MNT sessions or require prior authorization
  • Services provided as part of a broader preventive or wellness program may be subject to different coverage rules

Always verify current payer-specific MNT coverage, provider eligibility, and time-based billing requirements before submitting claims.
