ICD-10: M02.31

Reiter's disease, also known as reactive arthritis, is a type of inflammatory arthritis that typically arises following an infection, particularly in the urogenital or gastrointestinal tract. The ICD-10-CM code M02.31 specifically refers to Reiter's disease affecting the shoulder. 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. However, not all patients exhibit all three symptoms. The condition is often triggered by infections, particularly those caused by Chlamydia trachomatis, Salmonella, Shigella, or Yersinia species.

Symptoms

• Arthritis: The most prominent feature, which can affect various joints, including the shoulders, knees, and ankles. In the case of M02.31, the shoulder is specifically involved, leading to pain, swelling, and reduced range of motion.
• Urethritis: Inflammation of the urethra, which may present as painful urination or discharge.
• Conjunctivitis: Inflammation of the eye, leading to redness, irritation, and discharge.

Pathophysiology

The exact mechanism of Reiter's disease is not fully understood, but it is believed to involve an autoimmune response triggered by the initial infection. The body’s immune system mistakenly attacks its own tissues, leading to inflammation in the joints and other areas.

Diagnosis

Diagnosis of Reiter's disease typically involves:
- Clinical Evaluation: Assessment of symptoms and medical history.
- Laboratory Tests: Blood tests may reveal elevated inflammatory markers (e.g., ESR, CRP) and the presence of specific antibodies.
- Imaging Studies: X-rays or MRI may be used to assess joint involvement and rule out other conditions.

Treatment

Management of Reiter's disease focuses on alleviating symptoms and may include:
- Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): To reduce pain and inflammation.
- Corticosteroids: In cases of severe inflammation.
- Disease-Modifying Antirheumatic Drugs (DMARDs): In chronic cases that do not respond to NSAIDs.
- Antibiotics: If a bacterial infection is identified as the trigger.

Prognosis

The prognosis for individuals with Reiter's disease varies. Some may experience a single episode that resolves completely, while others may have recurrent symptoms or chronic arthritis. Early diagnosis and treatment are crucial for improving outcomes.

ICD-10 Code M02.31: Specifics

The ICD-10-CM code M02.31 is used to classify cases of Reiter's disease specifically affecting the shoulder. This code is part of the broader category of inflammatory arthropathies and is essential for accurate medical coding, billing, and epidemiological tracking.

The ICD-10 code M02.31 specifically refers to Reiter's disease affecting the shoulder. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with this condition.

Clinical Presentation

Reiter's disease typically presents with a triad of symptoms: arthritis, urethritis, and conjunctivitis. However, in cases where the shoulder is affected, the clinical presentation may focus more on the musculoskeletal symptoms.

Signs and Symptoms

1. Joint Pain and Swelling:
   - Patients often experience pain and swelling in the shoulder joint, which may be unilateral or bilateral. The pain can be acute and may worsen with movement or pressure on the joint[1].

2. Stiffness:
   - Morning stiffness is common, and patients may find it difficult to move the shoulder after periods of inactivity. This stiffness can improve with activity but may return after prolonged use[1].

3. Reduced Range of Motion:
   - Due to pain and swelling, patients may exhibit a limited range of motion in the shoulder, making it challenging to perform daily activities such as reaching overhead or lifting objects[1].

4. Systemic Symptoms:
   - Some patients may also report systemic symptoms such as fever, fatigue, and malaise, particularly if the underlying infection is still present[1].

5. Skin Manifestations:
   - In some cases, patients may develop skin lesions, such as keratoderma blennorrhagicum, which are associated with reactive arthritis[1].

6. Conjunctivitis:
   - Although not directly related to shoulder involvement, conjunctivitis may occur as part of the broader clinical picture of Reiter's disease, especially if the patient has a history of urogenital or gastrointestinal infections[1].

Patient Characteristics

1. Demographics:
   - Reiter's disease is more common in young adults, particularly males aged 20 to 40 years. However, it can affect individuals of any age and gender[1].

2. History of Infection:
   - A significant characteristic of patients with Reiter's disease is a recent history of infection, particularly with organisms such as Chlamydia trachomatis (often linked to urethritis) or gastrointestinal pathogens like Salmonella or Shigella[1].

3. Family History:
   - There may be a genetic predisposition, as individuals with a family history of HLA-B27 positivity are more likely to develop Reiter's disease[1].

4. Comorbid Conditions:
   - Patients may have other autoimmune or inflammatory conditions, which can complicate the clinical picture and management of Reiter's disease[1].

5. Lifestyle Factors:
   - Certain lifestyle factors, such as smoking or a sedentary lifestyle, may also influence the severity and progression of the disease[1].

Conclusion

Reiter's disease, particularly when affecting the shoulder, presents with a combination of joint pain, swelling, and stiffness, often following an infection. Understanding the clinical presentation and patient characteristics is crucial for timely diagnosis and management. If you suspect Reiter's disease in a patient, a thorough history, including recent infections and family history, along with a physical examination, is essential for effective treatment planning. Early intervention can help manage symptoms and improve the patient's quality of life.
