Drusen of optic disc, bilateral

This code signifies the presence of drusen, which are abnormal, acellular deposits, located on the optic disc in both eyes. These deposits can be superficial or buried within the optic nerve head, potentially leading to visual field defects or other optic neuropathies.

Utilize this code when documentation explicitly states the diagnosis of optic disc drusen affecting both eyes. This diagnosis is typically made through ophthalmoscopy, B-scan ultrasonography, or optical coherence tomography (OCT).

• Ensure documentation specifies "bilateral" involvement; otherwise, a unilateral code (H47.321 or H47.322) or unspecified code (H47.329) may be more appropriate.
• Do not confuse optic disc drusen with macular drusen (H35.31x), which are distinct conditions affecting different anatomical locations.
• Code any associated visual disturbances or optic neuropathies separately, following sequencing guidelines (e.g., H47.2x for optic atrophy).
