Gastroenterology Coding Alert

Gastroenterology Coding:

Use an Additional Code for This Chronic Ulcer Case

Question: A patient with a history of moderate alcohol dependence presented for a follow-up visit to the gastroenterologist to evaluate the status of the patient’s chronic stomach ulcer with perforation and hemorrhage. After reviewing the patient’s history and performing a physical examination, the physician collected a blood sample and ordered an abdominal X-ray to visualize the ulcer. An in-house radiologist captured the X-rays.

The gastroenterologist documented no changes to the patient’s condition. What diagnosis codes do I need to report for the encounter?

Answer: You’ll assign K25.6 (Chronic or unspecified gastric ulcer with both hemorrhage and perforation) to report the patient’s ulcer with hemorrhage and perforation and use F10.20 (Alcohol dependence, uncomplicated) to report the patient’s moderate alcohol dependence.

Locating the correct diagnosis code for the patient’s chronic ulcer with hemorrhage and perforation requires you to follow several indentations in the ICD-10-CM Alphabetic Index. Look for this pathway: Ulcer > stomach > with > hemorrhage > and perforation to land at K25.6, which you’ll verify in the Tabular List.

Parent code K25.- (Gastric ulcer) lists a use additional code note instructing you to identify the patient’s alcohol abuse and dependence with F10.- (Alcohol related disorders), if the information is documented. In your situation, the patient has a history of moderate alcohol dependence, which is covered by F10.20, as the additional condition “alcohol use disorder, moderate” is listed under the code.
