Name of the Condition

• Other Reactive Arthropathies, Left Shoulder (ICD Code: M02.812)

Summary

Reactive arthropathy is a form of arthritis that occurs as a reaction to an infection in another part of the body. The condition can cause pain and swelling in the joints, often affecting the left shoulder in this case.

Causes

• Reactive arthropathy follows infections, commonly bacterial infections in the gut, urinary tract, or genitals.
• They are often associated with infections caused by Chlamydia, Salmonella, Shigella, and Campylobacter.

Risk Factors

• Recent history of infections, especially those mentioned above.
• Genetic predisposition, such as the presence of the HLA-B27 gene.
• Age and biological sex, with younger men being more prone.
• Traveling to areas with certain endemic infections.

Symptoms

• Pain and stiffness in the left shoulder joint.
• Swelling and warmth around the shoulder area.
• Limited range of motion in the affected shoulder.
• Other symptoms may include eye redness, urinary issues, and skin rashes due to underlying infections.

Diagnosis

• Clinical evaluation based on symptoms and history of recent infections.
• Blood tests to identify inflammation markers or the presence of the HLA-B27 gene.
• Imaging tests, such as X-rays or MRIs, to assess joint damage.
• Synovial fluid analysis if needed to rule out other types of arthritis.

Treatment Options

• Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation.
• Antibiotics to treat any lingering infections.
• Corticosteroid injections in severe cases to decrease joint inflammation.
• Physical therapy to improve mobility and strengthen muscles around the shoulder.
• Disease-modifying antirheumatic drugs (DMARDs) for chronic or severe cases.

Prognosis and Follow-Up

• Symptoms often improve with treatment, but the condition can recur.
• Regular follow-up with a healthcare provider to monitor symptoms and adjust treatments as necessary.

Complications

• Chronic pain or stiffness if not adequately managed.
• Joint damage over time, leading to decreased mobility.
• Potential progression to other types of arthritis.

Lifestyle & Prevention

• Practicing good hygiene to prevent infections.
• Safe sexual practices to reduce the risk of sexually transmitted infections.
• Regular exercise and maintaining a healthy weight to support joint health.
• Diet rich in anti-inflammatory foods may aid in symptom management.

When to Seek Professional Help

• Persistent joint pain or stiffness lasting more than a few days.
• Signs of infection such as fever, chills, or new skin rashes.
• Sudden or severe worsening of symptoms.

Tips for Medical Coders

• Ensure the infection component is documented and verified when coding.
• Validate whether it specifically affects the left shoulder.
• Check for any additional codes needed for underlying infections or symptoms.
• Be careful to distinguish between reactive arthropathy and other types of arthritis.
