Overview of M13.89: Other Specified Arthritis

Arthritis is a term that describes inflammation of the joints, which can result from various causes, including autoimmune diseases, infections, and degenerative conditions. The designation "other specified arthritis" suggests that the arthritis may not be classified under common types such as rheumatoid arthritis or osteoarthritis but still requires effective management.

Standard Treatment Approaches

1. Pharmacological Treatments

Pharmacological management is often the first line of treatment for arthritis. The choice of medication depends on the severity of symptoms and the specific type of arthritis involved.

• Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): These are commonly used to reduce pain and inflammation. Examples include ibuprofen and naproxen. They can be effective for managing symptoms in various types of arthritis[1].

• Corticosteroids: Medications like prednisone may be prescribed to control inflammation and suppress the immune response, particularly in cases where arthritis is linked to autoimmune conditions[2].

• Disease-Modifying Antirheumatic Drugs (DMARDs): For inflammatory types of arthritis, DMARDs such as methotrexate or sulfasalazine may be utilized to slow disease progression and prevent joint damage[3].

• Biologic Agents: In cases where traditional DMARDs are ineffective, biologics like tocilizumab or abatacept may be considered. These target specific pathways in the inflammatory process and can be particularly beneficial for autoimmune-related arthritis[4][5].

2. Physical Therapy and Rehabilitation

Physical therapy plays a crucial role in managing arthritis. A tailored exercise program can help improve joint function, reduce stiffness, and enhance overall mobility. Techniques may include:

• Strengthening Exercises: Focused on building muscle around the affected joints to provide better support and stability.
