What is this code?

ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Diseases of the eye and adnexa (H00-H59).

When is it used?

  • May be used when a clinician documents optic nerve hypoplasia in a patient's medical record.
  • May appear in hospital records, claims, referrals, and clinical documentation.

What it does not mean

  • A code alone does not explain severity, treatment plan, or outcome.
  • A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
  • This entry may represent a broader category rather than the most specific billable code.
