History: The patient is a 79-year-old male with dyspepsia and weight loss. A recent supraclavicular lymph node biopsy revealed signet-ring cell adenocarcinoma.
Specimen site: Stomach
Gross description: Received in formalin is a 10.0- × 6.5- × 3.2-cm segment of stomach, with a palpable firm 4.0- × 2.2-cm mass on the designated lesser curvature. The external surface of the specimen is unremarkable and inked black. The cut surfaces demonstrate the mass and adjacent firm areas of nodularity. The remainder of the gastric mucosa is unremarkable. Six lymph node candidates and representative sections of the stomach are submitted.
Microscopic description: Microscopic examination was performed. See synoptic report. The uninvolved stomach shows chronic inactive gastritis with intestinal metaplasia.

Question

Quizplus · Accepted Answer

The correct ICD-10-CM code for this diagnosis is C16.5, which specifies a malignant neoplasm of the lesser curvature of the stomach, as the mass was located on the lesser curvature. The CPT codes 88309 and 88307 are used for the pathology examination of the stomach specimen and lymph nodes, respectively. The choice correctly reflects the need for both types of pathology examinations based on the specimen descriptions provided.
