Nondisplaced Fracture of Fifth Metatarsal Bone, Left Foot, Sequela (ICD S92.355S)

Name of the Condition

• Common name: Nondisplaced fracture of the fifth metatarsal
• Medical terminology: Fracture of the proximal fifth metatarsal, nondisplaced

Summary

Nondisplaced fractures of the fifth metatarsal bone occur when the bone breaks but remains in alignment. This particular case refers to a fracture on the left foot and is noted as a sequela, meaning it is the consequence or result of a previous injury or condition.

Causes

• Trauma or injury to the foot, such as twisting or direct impact.
• Overuse from repetitive motions or activities like running or jumping.

Risk Factors

• Participation in high-impact sports.
• Poor footwear, offering inadequate support.
• Pre-existing conditions, such as osteoporosis, which weaken bones.

Symptoms

• Pain and tenderness on the outer edge of the foot.
• Swelling or bruising in the affected area.
• Difficulty bearing weight on the foot.

Diagnosis

• Physical examination to assess the pain and tenderness.
• X-rays to confirm the alignment and specifics of the fracture.

Treatment Options

• Rest and reduced activity to promote healing.
• Immobilization using a cast or boot to keep the bone aligned.
• Physical therapy to restore strength and mobility after initial healing.

Prognosis and Follow-Up

• Most patients recover fully with appropriate treatment.
• Follow-up appointments are essential to monitor healing and prevent complications.

Complications

• Delayed union or nonunion, where the bone heals slowly or does not heal.
• Chronic pain or difficulty in regaining full function.

Lifestyle & Prevention

• Wearing supportive footwear to reduce risk of injury.
• Strength training exercises to build foot and lower leg muscles.
• Gradual increase in activity levels to avoid overuse.

When to Seek Professional Help

• Persistent or severe pain despite rest and care.
• Swelling that does not decrease or continues to increase.
• Inability to bear weight or use the foot properly.

• The National Institute for Health and Care Excellence (NICE) guidelines on fracture management.

Tips for Medical Coders

• Ensure to code the fracture as a sequela using the 'S' designation for this condition.
• Check documentation for confirmation of the nondisplaced nature of the fracture.
• Avoid confusing sequela with acute or healed injuries.
