S83.281 Other tear of lateral meniscus, current injury, right knee

Name of the Condition

• Other tear of lateral meniscus, current injury, right knee (ICD-10 Code: S83.281)

Summary

An other tear of the lateral meniscus, current injury, right knee refers to damage to the lateral (outer) meniscus in the right knee, classified as a current injury indicating recent onset or active symptoms. The lateral meniscus is a C-shaped cartilage structure that cushions the knee joint, and this type of tear may result from trauma or degenerative changes, potentially causing pain, swelling, or functional impairment.

Causes

Acute trauma, such as twisting or pivoting motions during physical activity. Degenerative wear and tear over time, particularly in older adults. Direct impact or force to the knee joint.

Risk Factors

• Participation in sports involving sudden stops, turns, or pivots (e.g., basketball, soccer).
• Older age, as cartilage naturally weakens with time.
• Previous knee injuries that may compromise joint stability.
• Obesity, which increases stress on the knee joint.

Symptoms

• Pain localized to the right knee, often worsened by movement.
• Swelling or stiffness in the joint.
• Difficulty fully bending or straightening the knee.
• A popping or clicking sensation during movement.
• Sensation of the knee locking or catching.

Diagnosis

Physical examination to assess range of motion, stability, and tenderness. Imaging tests, such as MRI, to visualize the meniscus and confirm the tear. Clinical history to determine the onset and mechanism of injury.

Treatment Options

• Non-surgical management, including rest, ice, compression, and elevation (RICE).
• Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and swelling.
• Physical therapy to improve strength and mobility.
• Surgical intervention, such as arthroscopy, for severe or displaced tears.

Prognosis and Follow-Up

Prognosis depends on the tear's severity and treatment. Most patients recover with conservative care, but surgical cases may require longer rehabilitation. Follow-up appointments monitor healing and functional recovery.

Complications

• Persistent pain or instability.
• Increased risk of osteoarthritis over time.
• Re-tear of the meniscus.
• Limited range of motion or stiffness.

Lifestyle & Prevention

• Strengthen knee muscles through targeted exercises.
• Use proper footwear and technique during physical activity.
• Maintain a healthy weight to reduce joint stress.
• Avoid sudden, forceful movements that strain the knee.

When to Seek Professional Help

Seek care if pain is severe, swelling persists, or the knee locks or catches. Immediate attention is needed for inability to bear weight or signs of infection (e.g., fever, redness).

Tips for Medical Coders

Document the specific location (lateral meniscus, right knee) and confirm the injury is current. Ensure clinical notes support the diagnosis and specify any additional details (e.g., tear type) to justify code assignment.
