S92.066K Nondisplaced intraarticular fracture of unspecified calcaneus, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced intraarticular fracture of unspecified calcaneus, subsequent encounter for fracture with nonunion

Summary

A nondisplaced intraarticular fracture of the calcaneus is a break in the heel bone where the fracture extends into the joint surface but the bone fragments remain in their normal alignment. This injury affects the subtalar joint and may cause pain, swelling, and limited mobility, though the joint structure is preserved. The "subsequent encounter for fracture with nonunion" designation indicates this is a follow-up visit for a fracture that has not healed properly, requiring ongoing management.

Causes

High-impact trauma, such as falls from a height or motor vehicle accidents, is a common cause. Direct force to the heel, often seen in sports injuries or workplace accidents, can also result in this fracture. Nonunion may occur due to inadequate immobilization, poor blood supply to the bone, or other factors that impede healing.

Risk Factors

• Participation in high-impact sports or activities.
• Occupations involving heights or fall risks.
• Osteoporosis or other bone-weakening conditions.
• Previous heel injuries or surgeries.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent heel pain, especially with weight-bearing.
• Swelling and bruising around the ankle and heel.
• Difficulty or inability to bear weight on the affected foot.
• Possible deformity of the heel.
• Limited mobility in the subtalar joint.

Diagnosis

Physical examination to assess pain, swelling, and deformity. Imaging tests, such as X-rays, CT scans, or MRI, to confirm the fracture and evaluate joint involvement, alignment, and signs of nonunion. Additional tests may be used to assess bone healing and blood supply.

Treatment Options

• Conservative management: Continued immobilization, physical therapy, or bone stimulation to promote healing.
• Surgical intervention: Bone grafting, internal fixation, or other procedures to address nonunion and restore function.
• Pain management: Medications or other therapies to control discomfort during recovery.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Follow-up care is essential to monitor healing and adjust treatment as needed. Long-term outcomes may include persistent pain or reduced mobility if the fracture does not heal properly.

Complications

• Chronic pain or arthritis in the subtalar joint.
• Persistent nonunion requiring additional surgery.
• Reduced mobility or functional impairment.
• Increased risk of future fractures due to weakened bone.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective footwear or equipment during sports or work.
• Maintain bone health through diet and exercise, as recommended.
• Follow post-treatment instructions to support healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after an injury. Contact your healthcare provider if symptoms worsen or do not improve with treatment, or if you notice signs of infection (e.g., fever, redness, or drainage).

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with nonunion, specifying the nondisplaced intraarticular nature of the calcaneus fracture. Include details on imaging results, treatment provided, and any complications. Ensure documentation supports the nonunion diagnosis and subsequent encounter status.
