ICD-10 Code H47.322 – Drusen of optic disc, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.322 – Drusen of optic disc, left eye
What it is
Drusen of the optic disc are calcified deposits at the optic nerve head. This code specifies the left eye only, so you should use it when documentation identifies left-sided optic disc drusen.
Clinical signs
Findings may include an elevated or irregular optic disc appearance and incidental discovery on eye exam. Clinical features vary; refer to documentation.
When to use this code
Use H47.322 when the provider documents optic disc drusen in the left eye, whether found during routine examination or evaluation of visual complaints. It also applies when imaging or ophthalmoscopy confirms the left optic disc involvement. Do not assign it for unspecified laterality.
Do not use for
Do not use this code for right eye or bilateral optic disc drusen, or when the record only says “optic disc drusen” without left-eye specification. Check documentation.
Coding tip
Confirm laterality from the ophthalmology note before coding, because the ICD-10-CM code is eye-specific.
