Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a history of stage IIIB non–small cell lung cancer treated with lobectomy and adjuvant chemoradiation presents to oncology clinic with progressive dyspnea and a new enlarging pulmonary nodule on surveillance CT. Imaging and tumor markers suggest disease recurrence. The oncology team coordinates an outpatient evaluation that may include image-guided biopsy for pathologic confirmation, restaging scans, and modification of systemic therapy. The clinical workflow includes obtaining informed consent, scheduling interventional radiology or thoracic surgery for biopsy, obtaining pathology and molecular testing, documenting recurrence in the medical record, and communicating changes to the patient’s primary care and payer. Billing uses HCPCS Level II code M1397 to denote services related to patients with recurrence/disease progression when applicable to administrative or care-management services tied to recurrence.
