S92.046 Nondisplaced other fracture of tuberosity of unspecified calcaneus

Name of the Condition

• Nondisplaced other fracture of tuberosity of unspecified calcaneus

Summary

This condition refers to a fracture of the tuberosity of the calcaneus (heel bone) that is not displaced, meaning the bone fragments remain in their normal alignment. The tuberosity is a bony prominence where the Achilles tendon attaches, and this type of fracture is classified as "other" to denote a specific, non-standard pattern. Nondisplaced fractures typically result from trauma or overuse and may heal with conservative management.

Causes

High-impact trauma, such as falls or direct blows to the heel, can cause this fracture. Repetitive stress or sudden force during activities like jumping or running may also lead to injury. The fracture is considered "unspecified" when the exact side (right or left) is not documented.

Risk Factors

• Participation in high-impact sports (e.g., running, basketball)
• Osteoporosis or weakened bone density
• Poor footwear or inadequate foot support
• Occupational hazards involving heavy lifting or falls

Symptoms

• Localized heel pain, especially with weight-bearing
• Swelling or bruising around the heel
• Tenderness at the tuberosity site
• Difficulty walking or standing

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays or CT scans, to confirm the fracture and evaluate its extent. The "unspecified" designation indicates the side of the calcaneus is not documented in the clinical record.

Treatment Options

• Rest and immobilization with a cast or splint to allow healing
• Pain management with medications or ice therapy
• Physical therapy to restore strength and mobility
• Surgical intervention for severe or unstable fracture (rare for nondisplaced cases)

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, and patients often regain full function. Follow-up appointments monitor healing progress, and imaging may be repeated to confirm alignment. Return to activity is gradual, guided by pain and mobility.

Complications

• Delayed healing or nonunion
• Chronic pain or stiffness
• Post-traumatic arthritis (rare)
• Nerve or tendon damage (if trauma is severe)

Lifestyle & Prevention

• Wear supportive footwear during high-impact activities
• Strengthen calf and ankle muscles to reduce stress on the heel
• Avoid sudden, forceful movements that strain the Achilles tendon
• Maintain bone health through diet and exercise

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility declines. Immediate attention is needed for severe trauma, open wounds, or signs of infection (e.g., redness, fever).

Tips for Medical Coders

Document the fracture as "nondisplaced" and "unspecified" when the side of the calcaneus is not documented. Ensure clinical notes specify the fracture type (tuberosity) and lack of displacement to support accurate coding. Use this code when the injury is not displaced and the side is not specified.
