Clinical & Coding Specifications
Clinical Context
A 52-year-old patient with type 2 diabetes mellitus and newly identified elevated hemoglobin A1c presents for an initial medical nutrition therapy visit with a registered dietitian who is credentialed to bill 97802. The patient is seen in an outpatient clinic setting (primary care or endocrinology clinic) for an individualized evaluation of current dietary intake, weight history, medication regimen, and glucose self-monitoring. The clinician documents a focused assessment, establishes individualized nutrition diagnoses and measurable goals, and provides specific diet therapy education and an initial care plan. Time spent face-to-face with the patient is documented in 15-minute increments for the visit. Supporting documentation includes the medical necessity linked to diabetes management, the initial assessment, treatment plan, patient education given, and planned follow-up.
