A reader question of the April 2004 General Surgery Coding Alert ("Diagnosis Matters for Screening Colonoscopy") contained a typographical error matching screening colonoscopy codes G0105 and G0121 to the incorrect diagnosis codes. The correct information follows: Additional approved codes for high-risk patients (G0105) include inflammatory bowel disease, including Crohn's disease or ulcerative colitis (for example, 558.2, 558.9, 555.0, 555.1, 555.2, 555.9, 556.1, 556.2, 556.3, 556.8, 556.9).
For G0105, approved ICD-9 codes include:
For patients with low or average risk (G0121), the most common approved diagnosis is V76.51 (Special screening for malignant neoplasms; intestine, colon).
