M65.151 Other infective (teno)synovitis, right hip

Name of the Condition

• Other infective (teno)synovitis, right hip
• ICD-10 Code: M65.151

Summary

This condition involves an infection of the synovial sheath surrounding tendons (tenosynovitis) or the synovial membrane of the right 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., animal bites, contaminated environments)
• Prior hip surgery or invasive procedures

Symptoms

• Localized swelling, warmth, and tenderness over the right hip
• Pain with movement or pressure
• Reduced range of motion or stiffness in the hip
• Systemic signs (e.g., fever, chills) if infection is severe or widespread
• 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 of the hip may aid recovery.

Prognosis and Follow-Up

With prompt treatment, most cases resolve without long-term complications. Follow-up may include monitoring for recurrence or residual impairment. Severe infections or delayed treatment can lead to chronic pain or joint damage.

Complications

• Chronic tenosynovitis or joint stiffness
• Spread of infection to surrounding tissues or bloodstream
• Joint damage or loss of function if untreated
• Recurrence of infection

Lifestyle & Prevention

• Maintain good wound hygiene, especially after hip injuries or procedures.
• Avoid activities that increase risk of trauma or infection in the hip area.
• Manage underlying conditions (e.g., diabetes) to reduce infection susceptibility.
• Seek timely care for minor injuries to prevent complications.

When to Seek Professional Help

Consult a healthcare provider if you experience persistent hip pain, swelling, fever, or difficulty moving the hip. Prompt evaluation is critical to prevent progression of infection.

Tips for Medical Coders

Document the specific anatomical site (right hip) and confirm infective etiology. Ensure clinical notes support the diagnosis, including signs of infection (e.g., fever, pus) or diagnostic test results (e.g., cultures). Use M65.151 only when the right hip is explicitly identified as the affected site.
