ICD-10 Code H47.392 – Other disorders of optic disc, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.392 – Other disorders of optic disc, left eye
What it is
This code identifies a disorder affecting the optic disc in the left eye that does not fit a more specific diagnosis. Use it when documentation names an optic disc abnormality but does not specify another exact condition.
Clinical signs
Clinical features vary; refer to documentation. Findings may include optic disc abnormalities on exam, such as swelling, pallor, or other structural changes, but the record must support a left-eye optic disc disorder.
When to use this code
Use H47.392 when the clinician documents an unspecified or other optic disc disorder limited to the left eye. It is appropriate for charted optic disc abnormalities that are not better described by a more specific ICD-10 code. If the note names a different optic nerve or retinal condition, code that diagnosis instead.
Do not use for
Do not use this code for generalized optic nerve disease, bilateral involvement, or a more specific optic disc diagnosis. Check documentation if the laterality or exact condition is unclear.
Coding tip
Verify that the record explicitly supports the left eye and an optic disc disorder before assigning H47.392.
