ICD-10: M02.371

Reiter's disease, also known as reactive arthritis, is a type of inflammatory arthritis that typically occurs as a reaction to an infection in another part of the body. The ICD-10 code M02.371 specifically refers to Reiter's disease affecting the right ankle and foot. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Reiter's Disease

Definition

Reiter's disease is characterized by a triad of symptoms: arthritis, urethritis, and conjunctivitis. It is often triggered by infections, particularly those caused by certain bacteria, such as Chlamydia trachomatis, Salmonella, Shigella, or Yersinia. The condition is more common in young adults and is associated with the HLA-B27 antigen, which is present in a significant number of affected individuals.

Symptoms

The symptoms of Reiter's disease can vary but typically include:
- Arthritis: Inflammation of the joints, which can be asymmetric and often affects the lower extremities, including the ankles and feet.
- Urethritis: Inflammation of the urethra, leading to painful urination and discharge.
- Conjunctivitis: Inflammation of the eye, causing redness, pain, and discharge.

In the case of M02.371, the focus is on the arthritis component, specifically affecting the right ankle and foot. Patients may experience:
- Swelling and tenderness in the right ankle and foot.
- Pain that may worsen with movement or pressure.
- Stiffness, particularly in the morning or after periods of inactivity.

Diagnosis

Diagnosis of Reiter's disease involves a combination of clinical evaluation and laboratory tests. Key diagnostic steps include:
- Medical History: Assessing recent infections or symptoms of urethritis or conjunctivitis.
- Physical Examination: Evaluating joint swelling, tenderness, and range of motion.
- Laboratory Tests: Blood tests may reveal elevated inflammatory markers (e.g., ESR, CRP) and the presence of the HLA-B27 antigen. Joint fluid analysis may also be performed to rule out other types of arthritis.

Treatment

Management of Reiter's disease primarily focuses on alleviating symptoms and addressing the underlying infection if present. Treatment options include:
- Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): To reduce pain and inflammation.
- Corticosteroids: May be prescribed for more severe inflammation.
- Disease-Modifying Antirheumatic Drugs (DMARDs): In chronic cases, medications like methotrexate may be considered.
- Antibiotics: If a bacterial infection is identified, appropriate antibiotics will be administered.

Prognosis

The prognosis for individuals with Reiter's disease varies. Many patients experience a self-limiting course, with symptoms resolving within months. However, some may develop chronic arthritis, which can lead to long-term joint damage if not managed effectively.

Conclusion

ICD-10 code M02.371 specifically identifies Reiter's disease affecting the right ankle and foot, highlighting the importance of accurate diagnosis and treatment.
