Idiopathic Chronic Gout, Left Ankle and Foot, Without Tophus (Tophi) (M1A.0720)

Name of the Condition

• Common name: Chronic gout
• Medical terms: Idiopathic chronic gout, gouty arthritis

Summary

Idiopathic chronic gout is a form of arthritis characterized by recurrent attacks of joint inflammation, typically affecting the left ankle and foot. The term "idiopathic" indicates that the exact cause of the condition is unknown, and "without tophus" means that there are no visible deposits of urate crystals (tophi) observed.

Causes

• The specific cause of idiopathic chronic gout is unknown. However, it is believed to be related to the body's inability to properly metabolize or eliminate uric acid, leading to its accumulation.

Risk Factors

• Increased risk of gout can be due to:
  • Genetics
  • Obesity
  • Diet rich in purines (e.g., red meat, seafood)
  • Excessive alcohol consumption
  • Certain medications, such as diuretics

Symptoms

• Pain and tenderness in the affected joints
• Swelling and redness around the left ankle and foot
• Limited range of motion
• Attacks often occur suddenly and repeatedly

Diagnosis

• Physical examination
• Serum uric acid test
• Joint fluid analysis
• Imaging tests (e.g., X-ray or ultrasound) to rule out the presence of tophi

Treatment Options

• Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), colchicine, and corticosteroids for pain relief
• Uric acid-lowering agents like allopurinol to prevent further attacks
• Lifestyle modifications to maintain healthy urate levels

Prognosis and Follow-Up

• With proper management, individuals with idiopathic chronic gout can lead an active life.
• Regular follow-ups with a healthcare provider to monitor uric acid levels and manage symptoms.

Complications

• Joint damage or deformity over time if left untreated
• Increased risk of developing chronic kidney disease

Lifestyle & Prevention

• Maintain a healthy weight
• Limit intake of foods high in purines
• Stay hydrated to help reduce uric acid levels
• Avoid excessive alcohol consumption

When to Seek Professional Help

• If experiencing sudden, intense pain in your ankle or foot
• Worsening of symptoms or more frequent attacks

Tips for Medical Coders

• Ensure correct laterality is documented—specifying the left ankle and foot.
• Confirm the absence of tophi in documentation.
• Double-check for related conditions to avoid miscoding (e.g., rheumatoid arthritis).
