ICD-10: M10.261

ICD-10 code M10.261 refers specifically to "Drug-induced gout, right knee." This classification falls under the broader category of gout, which is a type of inflammatory arthritis characterized by the accumulation of uric acid crystals in the joints, leading to sudden and severe pain, redness, and swelling.

Clinical Description of Drug-Induced Gout

Overview of Gout

Gout is primarily caused by hyperuricemia, a condition where there is an excess of uric acid in the blood. This can occur due to overproduction of uric acid or underexcretion by the kidneys. The condition often manifests as acute attacks of arthritis, with the big toe being the most commonly affected joint, although it can affect other joints, including the knees.

Drug-Induced Gout

Drug-induced gout occurs when certain medications lead to elevated uric acid levels, triggering gout attacks. Common medications associated with this condition include:

• Diuretics: Often used to treat hypertension and edema, diuretics can increase uric acid levels by promoting its reabsorption in the kidneys.
• Chemotherapy agents: Some cancer treatments can lead to rapid cell turnover, releasing purines that are metabolized into uric acid.
• Aspirin: Low doses of aspirin can inhibit uric acid excretion, contributing to hyperuricemia.

Symptoms

The symptoms of drug-induced gout are similar to those of primary gout and may include:

• Sudden onset of pain: Typically severe and often occurring at night.
• Swelling and redness: The affected joint, in this case, the right knee, may appear swollen and red.
• Limited range of motion: Pain and swelling can restrict movement in the affected joint.

Diagnosis

Diagnosis of drug-induced gout involves a combination of clinical evaluation and laboratory tests, including:

• Joint aspiration: To analyze synovial fluid for uric acid crystals.
• Blood tests: To measure serum uric acid levels, although these can be normal during an acute attack.

Treatment

Management of drug-induced gout focuses on both alleviating symptoms and addressing the underlying cause. Treatment options may include:

• Nonsteroidal anti-inflammatory drugs (NSAIDs): To reduce pain and inflammation.
• Colchicine: An effective medication for acute gout attacks.
• Corticosteroids: May be used if NSAIDs are contraindicated or ineffective.
• Modification of medication: If a specific drug is identified as the cause, it may need to be adjusted or replaced.

Conclusion

ICD-10 code M10.261 is crucial for accurately documenting cases of drug-induced gout affecting the right knee. Understanding the clinical implications, symptoms, and treatment options is essential for healthcare providers to manage this condition effectively. Proper coding not only aids in treatment but also ensures appropriate billing and resource allocation in healthcare settings.
