M71.861 Other specified bursopathies, right knee

Name of the Condition

• Other specified bursopathies, right knee

Summary

Other specified bursopathies of the right knee refer to inflammatory or non-inflammatory conditions affecting the bursae (small fluid-filled sacs that reduce friction between tissues) in the right knee region. These conditions may involve bursal irritation, swelling, or structural changes, leading to localized pain or functional impairment. The knee contains multiple bursae, and this code is used when the bursopathy is not classified under more specific knee bursitis codes.

Causes

Other bursopathies of the right knee can result from direct trauma, repetitive motion, infection, or systemic inflammatory conditions. They may also arise from metabolic or degenerative processes affecting the bursa, though the exact etiology varies by case. Overuse or acute injury to the knee joint or surrounding structures can contribute to bursal irritation.

Risk Factors

• Repetitive or prolonged pressure on knee bursae (e.g., from kneeling, squatting)
• Occupational or athletic activities involving repetitive knee use
• Pre-existing inflammatory conditions (e.g., rheumatoid arthritis)
• Recent injury or surgery near a knee bursa
• Age-related degenerative changes in the knee

Symptoms

• Localized pain or tenderness over the affected knee bursa
• Swelling or visible lump at the site
• Reduced range of motion in the right knee
• Discomfort with movement or pressure
• Possible warmth or redness if inflamed

Diagnosis

Diagnosis typically involves a physical examination to assess bursal characteristics, along with imaging (e.g., ultrasound, MRI) to evaluate tissue changes. Fluid aspiration or biopsy may be performed if infection or other pathology is suspected.

Treatment Options

Treatment may include rest, ice, compression, and elevation (RICE) to reduce inflammation. Nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroid injections may be used for pain relief. Physical therapy can help restore function, and surgical intervention is rarely required unless conservative measures fail.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though chronic or recurrent cases may require ongoing management. Follow-up care may involve monitoring for symptom resolution and functional improvement, with adjustments to treatment as needed.

Complications

Complications can include chronic pain, limited mobility, or infection if the bursa becomes inflamed or infected. Rarely, untreated bursopathies may lead to structural damage or require surgical intervention.

Lifestyle & Prevention

• Avoid prolonged kneeling or repetitive knee stress
• Use protective padding during activities that strain the knee
• Maintain a healthy weight to reduce joint pressure
• Engage in regular low-impact exercise to strengthen surrounding muscles
• Address underlying inflammatory conditions promptly

When to Seek Professional Help

Seek medical attention if pain is severe, persistent, or worsening; if swelling is significant or accompanied by redness/heat; or if mobility is severely limited. Prompt evaluation is important if infection is suspected (e.g., fever, pus drainage).

Tips for Medical Coders

Document the specific location (right knee) and any relevant clinical details to support the use of M71.861. Ensure the condition is not better classified under a more specific bursitis code. Include details about the bursa involved, symptoms, and diagnostic findings to justify the code selection.
