M1A.361
Chronic gout due to renal impairment, right knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Chronic gout is a form of arthritis caused by the buildup of uric acid crystals in the joints. When combined with renal impairment, it can lead to persistent joint inflammation, particularly affecting the knees. The ICD-10 code M1A.361 specifically describes cases of chronic gout affecting the right knee due to kidney problems. This condition requires careful management to prevent joint damage and address underlying kidney issues.
Causes & Symptoms
Clinical Causes: Elevated levels of uric acid in the blood, often due to decreased renal clearance Chronic kidney disease reducing the body's ability to eliminate uric acid Genetic predisposition to gout Diet high in purine-rich foods such as red meat, shellfish, and alcohol Obesity increasing uric acid production and impairing kidney function Certain medications that affect uric acid excretion, like diuretics
Key Symptoms: Persistent pain, swelling, and redness in the right knee Joint stiffness and limited range of motion Feeling of warmth over the affected joint Frequent flare-ups that can last days to weeks Possible presence of tophi, which are deposits of uric acid crystals under the skin Signs of worsening renal function, such as swelling in legs or high blood pressure
Diagnostic & Treatment
Diagnosis Path: Blood tests to measure levels of uric acid and kidney function Joint fluid analysis to identify uric acid crystals under a microscope Imaging studies such as X-rays or ultrasound to assess joint damage and deposits Evaluation of renal function through tests like serum creatinine and glomerular filtration rate (GFR)
Treatment Protocols: Medications to lower uric acid levels, such as allopurinol or febuxostat Anti-inflammatory drugs to reduce joint pain and swelling, including colchicine or NSAIDs Lifestyle modifications, including a low-purine diet, weight management, and limiting alcohol intake Adequate hydration to help flush out uric acid Treatment of underlying renal impairment to improve kidney function Regular monitoring of uric acid levels and kidney health to adjust treatment as needed
