This article was inspired by an article I read by Cynthia Tang and Richard Pinson (https://libmaneducation.com/coding-of-possible-malignancy-diagnoses-when-the-pathology-report-is-pending/). They expressed their concern about Coding Clinic’s advice to code an uncertain malignancy diagnosis…
Not all patients who present to the office with colon polyps will be diagnosed with colon cancer. This second-leading cause of cancer-related deaths in the US usually begins as small, benign adenomatous lump, and becomes cancerous overtime.
Colon cancer, or colorectal cancer as it’s regularly known, is a cancer which starts in the large bowel portion of the gastrointestinal (GI) system. Because it comes in many forms and symptoms, coding the definitive diagnosis might be risky. Guard your practice’s deserved dollars with these 3 tips.
1. Don’t Go Looking For ‘Benign’, ‘Malignant’
Whether or not you’re dealing with a full-blown colorectal cancer, you should be looking at the different terms used to describe benign or malignant colonic polyps. Some of these include:
But first, you have to accomplish the task of determining — without a doubt — if a polyp is benign or malignant. If you think you would find the clues in the pathology report (PR), think again. Usually, the PR will not use the term “benign” or “malignant.” However, it will use a description that points to the usual behavior of the polyp. It’s up to you to interpret those descriptions into benign or malignant.
Experts advise that you always wait for the pathology report to come back before deciding on a particular ICD-9. Even the gastroenterologists, themselves, usually defer to the pathology report before making a recommendation.

Eliminate ‘uncertain behavior’ confusion with expert tips
If you always use diagnosis code 238.2 (Neoplasm of uncertain behavior of skin) when you’re reporting 11100 (Biopsy of skin, subcutaneous tissue and/or mucous membrane [including simple closure], unless otherwise listed; single lesion) for a biopsy procedure your surgeon performs, you’re setting your practice up for disaster. The key to knowing when to use the “uncertain behavior” diagnosis code is understanding what that code descriptor really means. Follow these expert tips to ensure you’re choosing the correct diagnosis code for all your 11100 claims.
Wait For Pathology Before Choosing a Code
When your general surgeon performs a biopsy you should always wait until the pathology report comes back to choose the proper diagnosis and procedure codes to report – even though this will not always affect the CPT code you will wind up choosing.
Reason: The biopsy specimen’s pathology will affect the ICD-9 code you report, but most CPT procedure codes are not based on the specimen’s results. “There are a few CPT codes which are linked to specific diagnoses (for instance, excision of benign and malignant lesions), but overall CPT is about what you did; ICD-9 is about the outcome or the reason for it,” says Marcella Bucknam, CPC, CCS-P, CPC-H, CCS, CPC-P, COBGC, CCC, manager of compliance education for the University of Washington Physicians Compliance Program in Seattle.
Get to Know the Meaning Behind ‘Uncertain’ Codes
When you report 238.2 as the diagnosis for a biopsy procedure, you’re telling the payer that the pathologist said in his path report that he was uncertain as to the morphology of the lesion, says Barbara J. Cobuzzi, MBA, CPC, CENTC, CPC-H, CPC-P, CPC-I, CHCC, president of CRN Healthcare Solutions, a coding and reimbursement consulting firm in Tinton Falls, N.J., and senior coder and auditor for...
