ICD-10 Code H47.323 – Drusen of optic disc, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.323 – Drusen of optic disc, bilateral
What it is
H47.323 identifies drusen deposited in both optic discs. These are calcified, usually benign optic nerve head lesions that can be found incidentally on eye examination.
Clinical signs
Findings may include elevated, irregular optic discs with lumpy margins and possible pseudopapilledema. Visual fields can be normal or show nerve fiber layer defects; clinical features vary, refer to documentation.
When to use this code
Use this code when the provider documents optic disc drusen in both eyes, whether discovered during routine exam or workup for visual symptoms. It is appropriate when bilateral involvement is clearly stated in the record. Check documentation if laterality is uncertain or only one disc is affected.
Do not use for
Do not use this code for unilateral optic disc drusen, papilledema, or other optic nerve disorders. If the note does not confirm bilateral drusen, check documentation before assigning H47.323.
Coding tip
Confirm laterality from the ophthalmology note or imaging report before coding, because H47.323 is specific to both optic discs.
