Coding and claims
Returning Nutrition Client: 97802 or 97803?
Do not choose another initial nutrition assessment just because a client returns after a break or a new calendar year begins. For medical nutrition therapy, check the service performed, the payer’s rules and the remaining benefit separately. CPT 97802 and 97803 describe different assessment stages.
Initial assessment and reassessment are different services
In individual MNT, 97802 identifies initial assessment and intervention; 97803 identifies reassessment and subsequent intervention. Both are reported in 15-minute units. HHS’s nutrition billing guidance distinguishes these services. Neither the schedule label nor the length of an appointment is enough to decide between them.
A returning visit may involve an updated food history, changed goals or a detailed review of barriers without becoming another initial assessment. If staff are unsure, send the service question back to the dietitian and check the plan’s coding policy before submitting.
Medicare’s calendar year is a benefit question
Medicare’s basic MNT coverage is three hours in the first calendar year the beneficiary receives MNT and two hours in subsequent years. New annual hours do not, by themselves, establish that the dietitian performed an initial service again.
Eligibility is also limited: Medicare identifies diabetes, kidney disease, or a kidney transplant within the last 36 months, with a doctor’s referral and a qualifying dietitian or nutrition professional. Do not treat general nutrition counseling coverage under a commercial plan as interchangeable with the Medicare MNT benefit.
CMS NCD 180.1 provides an additional-hours pathway when a physician determines that a change in condition, diagnosis or treatment regimen requires a change in MNT and orders extra hours. Do not simply keep billing against an exhausted basic allowance; confirm the referral and claim requirements.
A fictional example: December assessment, January follow-up
A dietitian completes a beneficiary’s initial MNT assessment in December. The client returns in January to review progress and adjust the existing plan. Staff see a new year and wonder whether to reuse the initial assessment code.
The team checks the remaining calendar-year benefit and the documented service as separate tasks. If the January encounter is reassessment and intervention, a fresh annual allowance does not convert that work into an initial assessment. The dietitian selects the code supported by the service; billing staff confirm referral, coverage and units. The example does not establish eligibility or payment for a particular client.
A short pre-claim checklist
- Identify the payer/product and its MNT coverage policy.
- Confirm qualifying provider, condition and referral requirements.
- Record the prior initial assessment and subsequent MNT visits.
- Ask the dietitian to identify the actual service and supported time units.
- Check benefit hours used, including available history from other providers.
- Resolve additional-hours requirements before exceeding the basic allowance.
Avoid an automatic annual code reset
Keep the assessment-stage field separate from the benefit-year field in your workflow. If a plan allows a repeat initial assessment in specified circumstances, retain that policy and the clinical support. Do not create a universal annual-reassessment rule from one payer’s instructions.
Frequently asked questions
Does January 1 automatically allow another 97802?
No. A new benefit year does not establish the service type. Check what the dietitian performed and the payer’s rule for an initial versus subsequent service.
Are all nutrition visits covered by Medicare MNT?
No. Medicare has defined eligibility, referral and provider requirements. Commercial and Medicaid benefits require their own plan-specific review.
