S52.622G Torus fracture of lower end of left ulna, subsequent encounter for fracture with delayed healing

Name of the Condition

• Torus fracture of lower end of left ulna, subsequent encounter for fracture with delayed healing

Summary

A torus fracture of the lower end of the left ulna is a stable, incomplete break in the distal portion of the ulna, one of the two forearm bones. This type of fracture is characterized by buckling or compression of the bone cortex without significant displacement. The injury often results from trauma, such as a fall onto an outstretched hand, and may involve the wrist joint or adjacent soft tissues. The "subsequent encounter for fracture with delayed healing" modifier indicates this is a follow-up visit for a fracture that is not healing at the expected rate.

Causes

The most common cause is trauma, such as a fall onto an outstretched hand, a direct blow to the forearm, or high-impact injuries like sports-related incidents. The force transmitted through the wrist or elbow can lead to buckling of the distal ulna, particularly in pediatric patients with more pliable bone structures. Delayed healing may occur due to factors like poor blood supply, inadequate immobilization, or underlying medical conditions affecting bone repair.

Risk Factors

• Participation in contact sports or activities with a high risk of falls (e.g., gymnastics, skateboarding)
• Pediatric age group, as children’s bones are more prone to torus fractures
• Osteoporosis or reduced bone density (less common in children but relevant in older populations)
• Previous forearm or wrist injuries
• Certain occupations or hobbies involving repetitive stress or heavy lifting
• Conditions that impair bone healing (e.g., diabetes, smoking, nutritional deficiencies)

Symptoms

• Persistent or worsening pain at the injury site
• Swelling or tenderness over the distal ulna
• Limited range of motion in the wrist or forearm
• Visible deformity or abnormal contour of the bone (in some cases)
• Delayed return to normal function compared to typical healing timelines

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate healing progress. If delayed healing is suspected, additional imaging (e.g., CT or MRI) may be ordered to assess bone union and identify potential barriers to healing. Clinical correlation with the patient’s history and treatment adherence is also important.

Treatment Options

Treatment focuses on promoting healing and may include:

• Prolonged immobilization with a cast or splint to stabilize the fracture
• Pain management with over-the-counter or prescription medications
• Physical therapy to restore strength and mobility once healing allows
• In some cases, surgical intervention (e.g., bone grafting or fixation) if healing does not progress with conservative measures
• Addressing underlying factors contributing to delayed healing (e.g., nutritional support, smoking cessation)

Prognosis and Follow-Up

Most torus fractures heal well with appropriate treatment, but delayed healing may extend recovery time. Prognosis depends on the severity of the fracture, adherence to treatment, and any underlying conditions affecting bone repair. Follow-up visits are necessary to monitor healing progress, adjust treatment as needed, and ensure the fracture eventually unites. Long-term outcomes are generally favorable with proper management.

Complications

• Persistent pain or discomfort
• Nonunion (failure of the fracture to heal)
• Malunion (healing in an abnormal position)
• Limited range of motion or functional impairment
• Increased risk of future fractures in the affected area
• Nerve or vascular injury (rare, but possible with severe trauma)

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., wrist guards for sports)
• Maintain bone health through a balanced diet rich in calcium and vitamin D
• Avoid smoking and limit alcohol, as both can impair bone healing
• Engage in regular weight-bearing exercise to strengthen bones
• Follow safe practices to prevent falls (e.g., removing tripping hazards at home)

When to Seek Professional Help

Seek medical attention if:

• Pain worsens or does not improve with treatment
• Swelling, redness, or drainage occurs at the injury site
• There is new or increasing deformity
• Numbness, tingling, or weakness in the hand or fingers develops
• Healing does not progress as expected during follow-up visits

Tips for Medical Coders

This code (S52.622G) is specific to a torus fracture of the lower end of the left ulna with delayed healing during a subsequent encounter. Documentation should clearly indicate the fracture type, location (left ulna), and the reason for the encounter (delayed healing). Ensure the "subsequent encounter" modifier (G) is applied appropriately, and note any contributing factors to delayed healing (e.g., noncompliance, comorbidities) to support medical necessity. Avoid using this code for initial encounters or fractures without delayed healing.
