Final answer:
To code the surgical treatment of a comminuted intraarticular distal radial Colles' fracture, both CPT and ICD-10-CM codes must be used. The ICD-10-CM code would denote the specific type and location of the fracture, while the CPT code would describe the actual surgical procedure employed.
Step-by-step explanation:
The student is asking for the appropriate CPT and ICD-10-CM codes for a preoperative and postoperative diagnosis of a comminuted intraarticular distal radial Colles' fracture on the left wrist that was treated using a uniplanar fixation and closed reduction under fluoroscopy. For the CPT code, the procedure for the application of an external fixation system and closed reduction of a distal radial fracture is described. The precise CPT code would be dependent on the exact nature of the fixation system used and the details of the reduction process. This code can often be found in the musculoskeletal section under the subheading of fracture and/or dislocation treatment in the CPT manual.
The ICD-10-CM code for a comminuted intraarticular distal radial Colles' fracture would reflect the anatomical location, the type of fracture, and whether it is an initial or subsequent encounter for the fracture treatment. A code like S52.501A for a Colles' fracture of unspecified radius, initial encounter for closed fracture, could be used, adjusting the laterality and encounter specifics based on the exact details of the patient's case.
