M65.15 Other infective (teno)synovitis, hip

Name of the Condition

• Other infective (teno)synovitis, hip
• ICD-10 Code: M65.15

Summary

This condition involves an infection of the synovial sheath surrounding tendons (tenosynovitis) or the synovial membrane of the hip joint. It typically causes localized inflammation, pain, and functional impairment in the hip region.

Causes

The condition is most commonly caused by bacterial infections, though viral or fungal pathogens may also be involved. It can arise from direct inoculation (e.g., trauma, surgery) or hematogenous spread from a distant infection.

Risk Factors

• Recent hip injuries or procedures
• Immunocompromised states (e.g., diabetes, HIV)
• Poor wound hygiene or delayed treatment of minor injuries
• Occupational or recreational exposure to pathogens (e.g., contaminated environments)
• Prior hip surgery or invasive procedures

Symptoms

• Localized swelling, warmth, and tenderness over the hip
• Pain with movement or pressure
• Reduced range of motion or stiffness
• Systemic signs (e.g., fever, chills) if infection is severe
• Possible drainage or pus if the infection is advanced

Diagnosis

Diagnosis involves a physical exam to assess inflammation and mobility. Imaging (e.g., MRI, ultrasound) visualizes soft tissue changes, while laboratory tests (e.g., synovial fluid analysis, cultures) identify infectious agents.

Treatment Options

• Antibiotics are the primary treatment for bacterial infections. Surgical drainage or debridement may be necessary for abscesses or severe cases. Rest and immobilization may support recovery.

Prognosis and Follow-Up

Prognosis depends on early treatment and the severity of infection. Most patients recover with appropriate care, but delayed treatment can lead to chronic issues or joint damage. Follow-up monitoring ensures resolution and addresses complications.

Complications

• Chronic hip pain or stiffness
• Joint damage or degenerative changes
• Spread of infection to surrounding tissues or bloodstream
• Functional impairment requiring long-term management

Lifestyle & Prevention

• Maintain good wound hygiene, especially after injuries or procedures
• Seek prompt care for hip pain or swelling to prevent progression
• Manage underlying conditions (e.g., diabetes) to reduce infection risk
• Avoid activities that strain the hip until cleared by a provider

When to Seek Professional Help

Consult a healthcare provider if you experience persistent hip pain, swelling, fever, or reduced mobility. Immediate care is needed for signs of severe infection (e.g., pus, worsening symptoms).

Tips for Medical Coders

Document the anatomical site (hip) and confirm infective etiology. Include details on infection source, imaging, or lab results to support code specificity. Ensure documentation aligns with clinical findings for accurate coding.
