S92.312G Displaced fracture of first metatarsal bone, left foot, subsequent encounter for fracture with delayed healing

Name of the Condition

• Displaced fracture of first metatarsal bone, left foot, subsequent encounter for fracture with delayed healing
• ICD-10 Code: S92.312G

Summary

This condition involves a displaced fracture of the first metatarsal bone in the left foot, where bone fragments are shifted out of alignment. It is classified as a subsequent encounter, indicating ongoing care for the fracture, and is associated with delayed healing. The first metatarsal is a primary weight-bearing structure in the foot, and displacement can affect mobility and stability. Delayed healing suggests the fracture is not progressing as expected, requiring continued monitoring and intervention.

Causes

Direct trauma or impact to the left foot is the primary cause, such as a fall, sports injury, or dropping a heavy object. High-force impacts or twisting forces can force bone fragments out of alignment. Delayed healing may result from factors like poor blood supply, inadequate immobilization, or underlying health conditions that impair bone repair.

Risk Factors

• Participation in high-impact sports (e.g., running, basketball)
• Wearing improper or non-supportive footwear
• Conditions that weaken bones, such as osteoporosis or diabetes
• Previous foot injuries or fractures
• Advanced age, which may reduce bone density and balance
• Smoking or poor nutrition, which can hinder healing

Symptoms

• Persistent pain at the injury site, even with rest
• Swelling and bruising around the left foot
• Difficulty bearing weight on the affected foot
• Possible visible deformity if the fracture is severely displaced
• Delayed healing signs, such as lack of progress on imaging

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and mobility. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture, evaluate displacement, and assess healing progress. Blood tests may be ordered to check for underlying conditions affecting bone repair. The diagnosis confirms the fracture type, location, and status of healing.

Treatment Options

Treatment focuses on promoting healing and restoring function. Immobilization with a cast or brace may be used to stabilize the fracture. Weight-bearing restrictions are often recommended to reduce stress on the bone. Physical therapy helps restore strength and mobility once healing allows. In cases of severe displacement or nonunion, surgical intervention may be necessary to realign and fix the bone.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, adherence to treatment, and any underlying health factors. Delayed healing may extend recovery time, requiring closer monitoring. Regular follow-up appointments with imaging are typical to assess progress. Most patients recover with proper care, though some may experience long-term stiffness or reduced mobility.

Complications

• Nonunion (failure of the bone to heal)
• Malunion (healing in an incorrect position)
• Chronic pain or arthritis in the foot
• Nerve or tissue damage from the injury or surgery
• Infection (if surgical intervention is required)

Lifestyle & Prevention

• Wear supportive, properly fitting footwear to reduce injury risk.
• Avoid high-impact activities that stress the foot until fully healed.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Manage underlying conditions like diabetes or osteoporosis to promote healing.
• Use protective gear during sports to prevent trauma.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility declines. Contact a provider if you notice signs of infection (e.g., redness, fever) or if the fracture does not improve with treatment. Persistent difficulty bearing weight or delayed healing symptoms also warrant evaluation.

Tips for Medical Coders

Document the fracture's displacement, location (left foot), and encounter type (subsequent) clearly. Note any factors contributing to delayed healing, such as noncompliance with treatment or underlying conditions. Ensure imaging results and clinical assessments support the diagnosis to justify the code.
