S82.155G Nondisplaced fracture of left tibial tuberosity, subsequent encounter for closed fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of left tibial tuberosity, subsequent encounter for closed fracture with delayed healing

Summary

A nondisplaced fracture of the left tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches, with the bone fragments remaining aligned. This is a subsequent encounter for a closed fracture (no skin penetration) that has not healed within the expected timeframe. The tibial tuberosity is critical for knee extension, and delayed healing may prolong recovery. This condition requires ongoing monitoring to assess healing progress and adjust management as needed.

Causes

Traumatic injury is the primary cause, such as direct impact to the knee, falls, or sudden forceful contraction of the quadriceps muscle. Sports-related incidents, motor vehicle accidents, or other high-impact events can lead to this fracture. Delayed healing may result from factors like inadequate immobilization, poor blood supply to the area, or underlying health conditions affecting bone repair.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer)
• Adolescent growth spurts, especially in athletes
• Previous knee injuries or surgeries
• Activities involving sudden stops or jumps
• Conditions affecting bone healing (e.g., diabetes, smoking, nutritional deficiencies)

Symptoms

• Persistent localized pain and swelling over the tibial tuberosity
• Difficulty extending the knee or bearing weight
• Bruising or tenderness on palpation
• Minimal visible deformity due to nondisplacement
• Prolonged recovery compared to typical fracture healing timelines

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and functional limitations. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate alignment. Follow-up imaging (e.g., repeat X-rays) may be ordered to assess healing progress. Clinical evaluation focuses on identifying signs of delayed union, such as persistent pain or lack of radiographic evidence of bone bridging.

Treatment Options

• Continued immobilization (e.g., brace or cast) to support healing
• Pain management with analgesics or anti-inflammatory medications
• Physical therapy to maintain range of motion and muscle strength
• Weight-bearing restrictions as advised by the healthcare provider
• Surgical intervention (e.g., internal fixation) if healing does not progress with conservative measures

Prognosis and Follow-Up

Prognosis depends on the underlying cause of delayed healing and adherence to treatment. Most nondisplaced fractures eventually heal, but delayed healing may extend recovery time. Regular follow-up appointments are necessary to monitor healing through imaging and clinical assessment. Adjustments to treatment plans may be made based on progress.

Complications

• Prolonged pain or functional limitations
• Nonunion (failure of the fracture to heal)
• Chronic instability or weakness in the knee
• Increased risk of future fractures due to impaired bone strength
• Potential need for surgical intervention if healing does not occur

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Maintain a balanced diet rich in calcium and vitamin D to support bone health
• Quit smoking, as it impairs bone healing
• Use proper protective equipment during sports or high-risk activities
• Follow rehabilitation guidelines to strengthen the knee and prevent re-injury

When to Seek Professional Help

Seek medical attention if:

• Pain worsens or does not improve with treatment
• Swelling, bruising, or tenderness increases
• Difficulty bearing weight or extending the knee persists
• Signs of infection (e.g., redness, warmth, fever) develop
• Healing does not progress as expected during follow-up visits

Tips for Medical Coders

This code (S82.155G) is used for a subsequent encounter of a closed, nondisplaced left tibial tuberosity fracture with delayed healing. Documentation should specify the fracture type (nondisplaced, closed), laterality (left), and the reason for the encounter (delayed healing). Ensure the record includes details on healing status, treatment provided, and any adjustments to the care plan. Avoid using this code for initial encounters or open fractures.
