Orthopedic Coding Alert

Question: After an initial consult, our orthopedic surgeon documented suspected carpal tunnel syndrome (CTS). May I report CTS, or should I report the patient's signs and symptoms? Missouri Subscriber Answer: You should report the patient's signs and symptoms because the surgeon has not yet determined and documented a definitive diagnosis. Result: Instead of reporting 354.0 (Carpal tunnel syndrome), you should report the patient's documented signs and symptoms, such as the following: - pain in the hand, wrist and/or forearm (729.5, Pain in limb) - numbness and tingling (782.0, Disturbance of skin sensation) - muscle weakness (728.87, Muscle weakness [generalized]). Reason: ICD-9 official guidelines instruct you to use signs and symptoms codes in the office setting when the documented diagnosis is uncertain, stating: "Do not code diagnoses documented as -probable,- -suspected,- -questionable,- -rule out,- or -working diagnosis- or other similar terms indicating uncertainty. Rather, code the condition(s) to the highest degree of certainty for that encounter/visit, such as symptoms, signs, abnormal test results, or other reason for the visit" (Section IV. I, page 90).
