Here’s a detailed overview of this specific code, including its clinical description, symptoms, diagnosis, and relevant considerations.

Clinical Description of M10.47

Definition of Secondary Gout

Secondary gout occurs when hyperuricemia (elevated levels of uric acid in the blood) is caused by other underlying conditions or factors, rather than being primary or idiopathic. Conditions that can lead to secondary gout include renal insufficiency, certain medications, and metabolic disorders. The specific designation of M10.47 indicates that the gout is affecting the ankle and foot regions, which are common sites for gout attacks.

Symptoms

The symptoms associated with M10.47 typically include:
- Acute Pain: Sudden onset of intense pain in the ankle or foot, often described as throbbing or excruciating.
- Swelling: The affected joint may become swollen and tender to the touch.
- Redness and Warmth: The skin over the affected joint may appear red and feel warm.
- Limited Range of Motion: Patients may experience difficulty moving the affected joint due to pain and swelling.

Diagnosis

Diagnosing secondary gout involves several steps:
1. Clinical Evaluation: A thorough history and physical examination to assess symptoms and identify potential underlying causes.
2. Laboratory Tests: Blood tests to measure uric acid levels, kidney function, and other relevant markers. Joint fluid analysis may also be performed to check for the presence of monosodium urate crystals.
3. Imaging Studies: X-rays or ultrasound may be used to evaluate joint damage or inflammation.

Underlying Causes

Common underlying conditions that may lead to secondary gout include:
- Chronic Kidney Disease: Impaired renal function can lead to decreased excretion of uric acid.
