ICD-10 Code H43.23 – Crystalline deposits in vitreous body, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H43.23 – Crystalline deposits in vitreous body, bilateral
What it is
H43.23 identifies crystalline deposits in the vitreous body of both eyes. Use it when documentation states bilateral vitreous crystals or similar wording affecting both eyes.
Clinical signs
Findings may include visible crystalline material in the vitreous on eye exam and related visual complaints. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents crystalline deposits specifically in the vitreous body of both eyes. It fits ophthalmology notes, imaging, or exam findings that clearly identify bilateral involvement. If the record does not specify laterality or vitreous location, check documentation.
Do not use for
Do not use it for crystalline deposits in only one eye or for deposits located elsewhere in the eye. Do not assign it when the chart only mentions “crystals” without confirming vitreous involvement.
Coding tip
Confirm both laterality and vitreous location in the provider note before assigning H43.23.
