Question: Which ICD-9 codes prove medical necessity for Medicare's high-risk colorectal cancer screening exam?
Missouri Subscriber
Answer: When you report a high-risk colorectal cancer screening to Medicare (G0105, Colorectal cancer screening; colonoscopy on individual at high risk), the first step in proving medical necessity is strong diagnosis coding based on the patient's high-risk characteristics.
To help remember which patients meet Medicare's requirements for payment, save this list of common ICD-9 codes that indicate a patient may be at high risk for colorectal cancer:
- V10.05--Personal history of malignant neoplasm of large intestine
- V10.06--Personal history of malignant neoplasm of rectum, rectosigmoid junction and anus
- V12.72--Personal history of colonic polyps
- V16.0--Family history of malignant neoplasm, gastrointestinal tract
- V18.5--Family history of colon polyps
- V19.8--Family history of other condition (for instance, report V19.8 for family history of polyposis)
- 555.0--Regional enteritis of small intestine
- 555.1--Regional enteritis of large intestine
- 555.2--Regional enteritis of small intestine with large intestine
- 555.9--Regional enteritis of unspecified site
- 556.0--Ulcerative (chronic) enterocolitis
- 556.1--Ulcerative (chronic) ileocolitis
- 556.2--Ulcerative (chronic) proctitis
- 556.3--Ulcerative (chronic) proctosigmoiditis
- 556.8--Other ulcerative colitis
