S59.031G Salter-Harris Type III physeal fracture of lower end of ulna, right arm, subsequent encounter for fracture with delayed healing

Name of the Condition

• Salter-Harris Type III physeal fracture of lower end of ulna, right arm, subsequent encounter for fracture with delayed healing

Summary

This condition involves a Salter-Harris Type III fracture of the growth plate (physeal) at the lower end of the ulna in the right arm, with delayed healing during a subsequent encounter. It typically affects children and adolescents, where the fracture extends through the physis (growth plate) and into the epiphysis, potentially disrupting joint surfaces. The injury may result from trauma to the forearm, particularly near the wrist joint, and requires ongoing monitoring due to delayed healing.

Causes

Salter-Harris Type III physeal fractures often occur due to direct impact, such as a fall onto an outstretched hand, or from forceful twisting of the forearm. These injuries are common in activities involving sudden stops or collisions, where the growth plate is weaker than surrounding bone. Delayed healing may result from inadequate immobilization, poor blood supply, or underlying factors affecting bone repair.

Risk Factors

• Children and adolescents are at higher risk due to the presence of growth plates.
• Participation in contact sports or activities with a high likelihood of falls increases risk.
• Certain genetic or metabolic conditions affecting bone development may also elevate susceptibility.
• Inadequate initial treatment or non-compliance with immobilization protocols can contribute to delayed healing.

Symptoms

• Persistent pain and swelling near the wrist or forearm despite initial treatment.
• Difficulty moving the wrist or hand, with limited range of motion.
• Tenderness to touch at the fracture site during follow-up.
• Possible bruising around the affected area that does not resolve as expected.

Diagnosis

Physical examination by a healthcare professional to assess pain, swelling, and range of motion. Imaging tests, especially X-rays, to visualize the fracture and determine the extent of healing. Additional imaging (e.g., MRI) may be used if the fracture is not clearly visible or to evaluate for complications. Clinical correlation with the patient’s history of injury and treatment is essential.

Treatment Options

• Continued immobilization using a cast or splint to support healing.
• Pain management with medications as needed.
• Physical therapy to restore range of motion and strength once healing progresses.
• Surgical intervention may be considered if delayed healing persists or if there is displacement of the fracture.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and adherence to treatment. Most cases with delayed healing eventually heal with proper management, but recovery may take longer than typical fractures. Regular follow-up appointments are necessary to monitor healing progress and adjust treatment as needed. Long-term follow-up may be required to assess for growth disturbances or joint function.

Complications

• Persistent pain or stiffness in the wrist or forearm.
• Growth plate disturbances leading to limb length discrepancy or angular deformity.
• Post-traumatic arthritis if joint surfaces are affected.
• Nonunion or malunion of the fracture if healing is severely delayed.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with fall risks.
• Follow immobilization and weight-bearing restrictions as advised.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.

When to Seek Professional Help

Seek immediate medical attention if there is increased pain, swelling, or deformity at the fracture site. Contact a healthcare provider if symptoms worsen or do not improve with treatment, or if there are signs of infection (e.g., redness, warmth, fever). Follow-up is critical to ensure proper healing and address any complications promptly.

Tips for Medical Coders

This code is used for a subsequent encounter for a Salter-Harris Type III physeal fracture of the lower ulna (right arm) with delayed healing. Documentation should specify the fracture type, location, laterality, and the presence of delayed healing. Ensure the encounter is classified as "subsequent" and that the reason for the visit relates to the fracture’s delayed healing. Code assignment requires clear clinical correlation between the diagnosis and the documented findings.
