S92.335D Nondisplaced fracture of third metatarsal bone, left foot, subsequent encounter for fracture with routine healing

Name of the Condition

• Nondisplaced fracture of third metatarsal bone, left foot, subsequent encounter for fracture with routine healing.

Summary

A nondisplaced fracture of the third metatarsal bone in the left foot is a break in the long bone connecting the ankle to the toes, where the bone fragments remain in their normal alignment. This code is used for a subsequent encounter during the healing phase, indicating the fracture is progressing as expected without complications. The injury typically results from trauma or repetitive stress and may not require surgical intervention, depending on the extent of the fracture.

Causes

Direct trauma to the left foot, such as a fall, sports injury, or dropping a heavy object, is a common cause. Repetitive stress from activities like running or jumping can also lead to stress fractures over time. The "subsequent encounter" designation applies when the patient is being seen for follow-up care during the routine healing process.

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
• Previous foot injuries or fractures

Symptoms

• Pain and tenderness in the midfoot area of the left foot
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the left foot
• Minimal to no visible deformity due to the nondisplaced nature

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 determine if it is nondisplaced. For a subsequent encounter, documentation should show evidence of routine healing, such as callus formation or reduced pain.

Treatment Options

• Rest and immobilization, often using a cast or walking boot, to allow healing
• Over-the-counter pain relievers such as acetaminophen or NSAIDs
• Physical therapy to restore strength and mobility once healing is advanced
• Follow-up imaging to monitor progress if needed

Prognosis and Follow-Up

Most nondisplaced fractures of the third metatarsal bone heal well with conservative treatment. Routine follow-up is important to ensure proper healing and to adjust treatment as needed. Full recovery may take several weeks to months, depending on the severity of the injury and adherence to treatment plans.

Complications

• Delayed healing or nonunion if the fracture does not heal properly
• Chronic pain or stiffness in the foot
• Arthritis in the affected joint over time
• Re-fracture if the bone is not fully healed before resuming normal activities

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities
• Gradually increase activity levels to avoid overuse injuries
• Maintain bone health through a balanced diet rich in calcium and vitamin D
• Use protective gear during high-impact sports

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or if there is difficulty bearing weight. Signs of infection, such as redness, warmth, or pus, also require prompt evaluation.

Tips for Medical Coders

This code is specific to a nondisplaced fracture of the third metatarsal bone in the left foot during a subsequent encounter for routine healing. Documentation should clearly indicate the fracture type, location, and that the encounter is for follow-up of a healing fracture. Ensure the "subsequent encounter" designation is supported by clinical notes showing ongoing care for the fracture.
