ICD-10 Code H43.20 – Crystalline Deposits in Vitreous Body, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H43.20 – Crystalline deposits in vitreous body, unspecified eye
What it is
This code identifies crystalline material noted in the vitreous body of an unspecified eye. Use it when the record describes vitreous crystals or deposits but does not specify the eye.
Clinical signs
Findings may include visible vitreous crystals on eye examination or imaging, sometimes with floaters or blurred vision. Clinical features vary; refer to documentation.
When to use this code
Use H43.20 when the provider documents crystalline deposits in the vitreous and does not identify right or left eye. It also fits cases where the diagnosis is confirmed but laterality is not recorded. Check documentation if the note suggests another vitreous disorder instead.
Do not use for
Do not use this code for crystalline deposits in a specified eye when laterality is documented. Do not use it for other vitreous opacities, hemorrhage, or detachment unless the record clearly states crystalline deposits.
Coding tip
Verify laterality first; if the chart names the eye, choose the specified-eye code instead of H43.20.
