The correct ICD-10-CM code for a signet-ring cell adenocarcinoma located on the lesser curvature of the stomach is C16.5. The CPT codes 88309 for the pathology examination of the stomach specimen and 88307 for the lymph node biopsy are appropriate, reflecting the procedures described in the history and specimen report.
