S92.145G Nondisplaced dome fracture of left talus, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced dome fracture of left talus, subsequent encounter for fracture with delayed healing

Summary

A nondisplaced dome fracture of the left talus is a break in the dome-shaped upper surface of the talus bone on the left side, where the bone fragments remain in their normal alignment. This injury affects the ankle joint, potentially disrupting weight-bearing and movement. The talus connects the foot to the lower leg and is critical for ankle function. The "subsequent encounter for fracture with delayed healing" indicates this is a follow-up visit for a fracture that is not healing at the expected rate.

Causes

Direct trauma to the ankle, such as falls, sports injuries, or motor vehicle accidents, is the most common cause. High-impact forces or twisting motions can also lead to dome fractures, particularly in activities involving sudden stops or changes in direction.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer) or activities with a risk of ankle injury.
• Osteoporosis or other conditions that weaken bone density.
• Previous ankle or talus injuries.
• Improper footwear or inadequate protective gear during physical activities.

Symptoms

• Sudden, severe pain in the ankle or foot.
• Swelling and bruising around the injury site.
• Difficulty bearing weight or walking.
• Limited range of motion in the ankle joint.
• Possible deformity or abnormal positioning of the foot.

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays, CT scans, or MRIs, are typically used to confirm the fracture and evaluate healing progress. The provider may also assess for signs of delayed healing, such as persistent pain or lack of bone union over time.

Treatment Options

Treatment focuses on promoting healing and restoring function. This may include immobilization with a cast or brace, pain management, and physical therapy to improve mobility and strength. In cases of significant delay, additional interventions like bone stimulation or surgery may be considered.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and adherence to treatment. Delayed healing may prolong recovery, but most fractures eventually heal with proper care. Follow-up appointments are essential to monitor progress and adjust treatment as needed.

Complications

Potential complications include nonunion (failure to heal), avascular necrosis (loss of blood supply to the bone), arthritis, or chronic pain. These risks are higher with delayed healing.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use proper footwear and protective gear during sports.
• Maintain bone health through a balanced diet and regular exercise.
• Follow rehabilitation guidelines to support healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility does not improve. Also, consult a provider if you notice signs of infection (e.g., redness, fever) or new deformity.

Tips for Medical Coders

Document the encounter as a subsequent visit for a fracture with delayed healing. Ensure clinical notes specify the fracture type (nondisplaced dome), location (left talus), and evidence of delayed healing (e.g., imaging findings or clinical assessment). Code S92.145G is appropriate when the fracture is being treated during the healing phase with delayed progress.
