Question: Texas Subscriber Answer: Since you're reporting procedures completed in the same area, you'll bill one or the other, but not both. Codes 20100-20103 (Exploration of penetrating wound [separate procedure] ...) represent trauma cases with penetrating wound exploration (such as shooting, stabbing, or accidental laceration), not evacuation of hematoma. If the case you're coding doesn't meet the criteria outlined in CPT's Musculoskeletal System explanatory notes for this code family, CPT directs you to report the specific repair code(s) from the Integumentary System section. Code 10140 (Incision and drainage of hematoma, seroma or fluid collection) represents incision and drainage of hematoma and will usually be the best coding choice.
