S92.314G Nondisplaced fracture of first metatarsal bone, right foot, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of first metatarsal bone, right foot, subsequent encounter for fracture with delayed healing
• ICD-10 Code: S92.314G

Summary

A nondisplaced fracture of the first metatarsal bone in the right foot is a break where the bone fragments remain in their normal alignment. This subsequent encounter code indicates the patient is receiving active treatment for delayed healing of the fracture. The first metatarsal is the long bone connecting the big toe to the midfoot and is a primary weight-bearing structure. Delayed healing may occur due to factors like poor blood supply, inadequate immobilization, or underlying health conditions. The injury is localized to the right foot and may affect mobility and stability during the healing process.

Causes

Direct trauma to the right foot is the most common cause, such as dropping a heavy object, a sports injury, or a fall. High-force impacts may lead to a fracture, while repetitive stress from activities like running or jumping can result in stress fractures over time. Delayed healing may be attributed to inadequate immobilization, poor blood supply to the bone, or underlying conditions like diabetes or smoking, which impair the body’s ability to repair the fracture.

Risk Factors

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

Symptoms

• Persistent pain and tenderness at the base of the big toe (right foot)
• Swelling or bruising that does not improve over time
• Difficulty bearing weight or walking on the injured foot
• Possible limited range of motion in the big toe

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and mobility. Imaging studies, such as X-rays or MRI, are typically used to confirm the fracture and evaluate healing progress. The provider may also review the patient’s medical history and previous treatment to determine if healing is delayed. Additional tests, like blood work, may be ordered to identify underlying conditions affecting healing.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a cast or boot to stabilize the bone. Weight-bearing restrictions are often recommended to reduce stress on the fracture. Pain management with medications or physical therapy may be used to improve mobility. In some cases, surgical intervention, such as bone grafting or fixation, may be necessary if healing does not progress.

Prognosis and Follow-Up

Prognosis depends on the cause of delayed healing and the effectiveness of treatment. Most nondisplaced fractures heal with proper care, but delayed healing may extend recovery time. Regular follow-up appointments with imaging are typically scheduled to monitor progress. Compliance with immobilization and activity restrictions is critical to achieving full recovery.

Complications

• Prolonged pain or discomfort
• Nonunion (failure of the bone to heal)
• Malunion (healing in an abnormal position)
• Chronic instability or arthritis in the big toe joint
• Increased risk of future fractures due to weakened bone

Lifestyle & Prevention

• Wear supportive footwear to reduce stress on the foot.
• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Manage underlying conditions like diabetes or osteoporosis to improve healing.
• Quit smoking, as it impairs bone healing.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility declines. Contact a provider if the foot shows signs of infection, such as redness, warmth, or drainage. Immediate care is needed if the foot becomes deformed or if weight-bearing is impossible.

Tips for Medical Coders

Use this code for a subsequent encounter where the fracture is nondisplaced and healing is delayed. Document the fracture’s status (nondisplaced) and the reason for delayed healing (e.g., poor blood supply, inadequate immobilization) to support code assignment. Ensure the encounter is classified as "subsequent" and not initial or acute. Verify that the injury is localized to the right foot and that active treatment for healing is being provided.
