Diagnosis Overview

What is Uveitis?
Essential facts and insights about Uveitis

Key Clinical Considerations:

  • Eye redness, pain, photophobia, blurred vision
  • Slit-lamp examination revealing inflammation in the uvea
  • Fundoscopic exam showing keratic precipitates or inflammatory cells in the anterior chamber

Clinical Information

Clinical Criteria & Documentation Requirements

  • Patient history including onset, duration, and associated symptoms
  • Specific terminology such as 'anterior uveitis', 'posterior uveitis', or 'panuveitis'
  • Examples: 'Patient presents with unilateral anterior uveitis with photophobia and redness.'

Coding Guidelines

Usage Guidelines & Examples

  • Usage guidelines: Use specific codes based on the type of uveitis.
  • Common errors: Misclassifying uveitis as conjunctivitis or failing to specify the type.

Code Exclusions

Important Exclusions

  • Excluded conditions: Conjunctivitis, keratitis, and other non-inflammatory eye conditions.
  • Alternative codes: Consider codes for associated systemic diseases if applicable.
