Clinical information

An ankle fracture, also known as a broken ankle, is a fracture or multiple fractures of the bones in the ankle joint: tibia, fibula, and talus. Three of the most common ankle fractures are:

Lateral malleolus fracture is a fracture on the end of the fibula, the bone located on the outer side of the ankle
Bimalleolar ankle fracture is a fracture in the lateral malleolus and the medial malleolus, which is the bone at the end of the tibia on the inner side of the ankle.
Trimollar ankle fracture is a fracture in the lateral malleolus, medial malleolus, and posterior malleolus, which is the back part of the tibia.

Aside from categorizing the fractures by area, they are also classified by whether or not they have been displaced.

Some causes of an ankle fracture are high-force impact, tripping/falling from a high area, and twisting/rolling/turning one’s ankle while walking or running. Symptoms of an ankle fracture are swelling, bruising, severe pain, tenderness, inability to place weight on the injured foot, and deformity in the ankle joint.

To diagnose an ankle fracture, a practitioner will physically examine the affected leg and may also have the patient undergo imaging tests, such as X-rays, CT scans, and MRI scans. Treatment will vary depending on the severity or type of injury. In extreme cases, surgery will be required. However, treatments for nondisplaced fractures may include a short leg cast, removable brace, or walking boot.

Commonly asked questions

Use a Right Ankle Fracture ICD-10-CM code when a confirmed diagnosis of a fracture involving the right tibia, fibula, or ankle joint is documented. The code should reflect the specific type, location, and encounter (initial, subsequent, or sequela) to ensure accurate medical billing and reporting.

Yes, Right Ankle Fracture diagnoses are billable when a complete and specific ICD-10-CM code is used, including the appropriate 7th character (A, D, or S). Codes without this required detail are not valid for reimbursement.

Common treatments include immobilization with a cast or walking boot for nondisplaced fractures and surgical intervention (e.g., internal fixation) for displaced or complex cases. Physical therapy is often recommended during recovery to restore strength, mobility, and function.
