All you need to report are signs and symptoms when diagnostics come back normal. You think you may have mastered most ICD-9 challenges, but do you know how to deal with a diagnostic test that comes back sans a definitive diagnosis? When you make sure to convey to payers exactly what you found, you'll overcome these challenges. Here are sure-fire ways how to do that. Follow 3 Rules for Normal Diagnostics Results Scenario 1: The gastroenterologist refers a patient to a radiologist for an abdominal CT scan (74150-74170) with a symptom of abdominal pain (789.0). The CT scan, when interpreted by the GI, reveals the presence of an abscess. Both the radiologist -- when reporting for the technical component of the CT scan, and the gastroenterologist -- when reporting for the professional component of the same test, should report a diagnosis of "intra-abdominal abscess" (567.22, Peritoneal abscess). Challenge: Beware of three alternative rules: Rule 1: Rule 2: Rule 3: Remember: Tackle This Chronic Condition Scenario Scenario 2: A patient already diagnosed with liver cancer visited the gastroenterologist for esophageal varices. On the first line of your claim, you would list 456.1 (Esophageal varices without bleeding) for the presenting problem (varices), and then report 155.0 (Malignant neoplasm of liver primary) for the chronic disease (hepatocellular carcinoma). Challenge: Do not code the chronic condition if it is unrelated to the primary reason for the visit, counsels Becky Zellmer, CPC, MBS, CBCS, operations supervisor for Madison, Wis.- based SVA Healthcare Services. For instance, the liver cancer patient in Example 2 presents with dyspepsia, code only 536.8 (Dyspepsia and other specified disorders of function of stomach), and not 155.0. Don't Overlook V Codes For Preop Exams Scenario 3: If a patient who is scheduled for a gall bladder surgery presents for a pre-op evaluation. The GI lists the condition prompting the surgery as acute cholecystitis (575.0) and the underlying medical condition as diabetes (250.xx). Challenge: Sometimes, a physician would order a diagnostic test in the absence of signs and symptoms, or perform a preop evaluation for the patient. If the chief reason for the encounter is a preop evaluation, list first a code from category V72.8 (Other specified examinations) to describe the preop evaluation. Then, assign a code for the condition prompting the surgery as an additional diagnosis (in this case, 575.0). Any condition discovered during the screening should be reported as additional diagnosis (i.e., 250.xx in the scenario given). V codes take the spotlight, too, when a patient has no signs or symptoms and the gastroenterologist performs a test solely for screening purposes. In this case, you should disregard typical diagnosis codes and locate an applicable "V" code to describe the test to the payer. Be careful with the V codes, however. Many payers will not pay for claims with only a V code as a diagnosis, with the exception of physicals or covered preventative health services, and, even then, they will only pay for one adult physical a year.
