S92.356G Nondisplaced fracture of fifth metatarsal bone, unspecified foot, subsequent encounter for fracture with delayed healing

Name of the Condition

• Technical Term: Nondisplaced fracture of fifth metatarsal bone, unspecified foot, subsequent encounter for fracture with delayed healing
• ICD-10 Code: S92.356G
• Common Name: Broken fifth metatarsal (unspecified foot, delayed healing, subsequent encounter)

Summary

A nondisplaced fracture of the fifth metatarsal bone in the unspecified foot is a break in the long bone on the outer edge of the foot where the bone fragments remain in their normal alignment. This is a subsequent encounter for a fracture with delayed healing, indicating the fracture has not progressed as expected during the healing process. The injury typically results from trauma or repetitive stress and requires ongoing evaluation to monitor healing and adjust treatment.

Causes

Direct trauma to the foot, such as a fall, twist, or impact, is the most common cause. Repetitive stress from activities like running or jumping may also lead to stress fractures over time. Delayed healing can occur due to factors like poor blood supply, inadequate immobilization, or underlying health conditions affecting bone repair.

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 poor nutrition, which can impair healing

Symptoms

• Persistent pain and tenderness on the outer edge of the foot
• Swelling or bruising that does not resolve
• Difficulty bearing weight or walking
• Possible lack of improvement in symptoms over time

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, are typically used to confirm the fracture and evaluate healing progress. Additional tests, like CT scans or MRIs, may be ordered if delayed healing is suspected to assess bone union or identify complications.

Treatment Options

• Continued immobilization with a cast or boot to support healing
• Pain management with medications or physical therapy
• Weight-bearing restrictions to reduce stress on the fracture
• Surgical intervention if healing does not progress or complications arise
• Nutritional support or lifestyle modifications to promote bone health

Prognosis and Follow-Up

Most nondisplaced fractures with delayed healing eventually heal with appropriate treatment, though recovery may take longer than usual. Regular follow-up appointments are necessary to monitor healing through imaging and adjust treatment plans. Full recovery depends on adherence to recommendations and addressing any underlying factors contributing to delayed healing.

Complications

• Nonunion, where the fracture fails to heal properly
• Malunion, where the bone heals in an abnormal position
• Chronic pain or reduced mobility
• Increased risk of future fractures in the affected area

Lifestyle & Prevention

• Wear supportive footwear to reduce stress on the foot
• Avoid high-impact activities until cleared by a healthcare provider
• Maintain a balanced diet rich in calcium and vitamin D to support bone health
• Engage in low-impact exercises, such as swimming, to maintain fitness without stressing the foot
• Address any underlying conditions, like osteoporosis, to reduce fracture risk

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or there is no improvement in symptoms after treatment. Immediate care is needed if there is new deformity, inability to bear weight, or signs of infection (e.g., redness, warmth, fever).

Tips for Medical Coders

Document the fracture type (nondisplaced), location (fifth metatarsal, unspecified foot), and encounter type (subsequent) clearly. Note the presence of delayed healing to justify the use of code S92.356G. Include details about treatment plans, imaging results, and follow-up visits to support coding accuracy. Ensure documentation reflects the ongoing nature of the fracture and any factors contributing to delayed healing.
