M1A.39

Chronic gout due to renal impairment, multiple sites

Clinical Classification Guidelines

Medical Intelligence & Overview

Chronic gout due to renal impairment is a form of gout that develops over time and is associated with kidney problems. Gout is a form of arthritis caused by the buildup of uric acid crystals in the joints, leading to inflammation, pain, and swelling. When the kidneys are impaired, their ability to eliminate uric acid from the body decreases, resulting in increased uric acid levels and the development of gout, often affecting multiple joints throughout the body. This condition requires careful management to prevent joint damage and reduce symptoms.

Causes & Symptoms

Clinical Causes: Chronic kidney disease or renal impairment reduces the kidneys' ability to filter and excrete uric acid effectively. Prolonged elevated uric acid levels due to impaired renal function lead to crystal formation in joints. Lifestyle factors such as diet high in purines, alcohol consumption, and obesity can contribute to higher uric acid levels alongside renal issues. Genetic predisposition may also play a role in the development of gout in individuals with kidney problems.

Key Symptoms: Persistent joint pain, especially in multiple sites, often involving the toes, ankles, knees, wrists, or elbows. Swelling, redness, and warmth around affected joints. Recurrent gout attacks that may become more frequent over time. Formation of tophi, which are deposits of uric acid crystals under the skin, particularly in chronic stages. Limited joint movement and potential joint destruction if untreated.

Diagnostic & Treatment

Diagnosis Path: Blood tests to measure serum uric acid levels, which are often elevated in gout. Joint fluid analysis to identify uric acid crystals under microscopic examination. Imaging studies such as X-rays or ultrasound to detect joint damage or tophi. Assessment of kidney function through blood tests like serum creatinine and glomerular filtration rate (GFR).

Treatment Protocols: Medications such as urate-lowering therapies (e.g., allopurinol, febuxostat) to reduce uric acid production. Anti-inflammatory drugs like colchicine or NSAIDs to manage acute attacks. Lifestyle modifications including dietary changes to reduce purine intake, limit alcohol consumption, and maintain a healthy weight. Ensuring adequate hydration to help the kidneys eliminate uric acid more efficiently. Monitoring kidney function regularly to adjust treatments and prevent further renal decline.

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
