What This Code Means

Coding Tips

•Use this code only when laterality is not specified in the medical record
•Query the provider to clarify which eye is affected for more accurate coding

Clinical Significance

✓Clinical evidence of corneal infection
✓Ophthalmologic examination findings
✓Rationale for unspecified laterality (bilateral involvement, unclear documentation)
✓Treatment plan for infection management
✓Visual symptoms and examination findings
✓Provider assessment confirming transplant-related infection
✓Follow-up plans for laterality determination if possible
