ICD-10 Code H27.01 – Aphakia, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.01 – Aphakia, right eye
What it is
H27.01 identifies aphakia in the right eye, meaning the natural lens is absent. Use it when documentation confirms the right lens has been removed or is missing.
Clinical signs
Clinical features vary; refer to documentation. Common findings include markedly reduced focusing ability and history of lens extraction, trauma, or congenital absence affecting the right eye.
When to use this code
Use this code when the provider documents aphakia specifically in the right eye. It may follow cataract surgery, lens dislocation with removal, or traumatic lens loss, but only if the right eye is clearly identified.
If the record mentions both eyes, code the documented laterality or use a bilateral code if supported. Check documentation when laterality is unclear or when the lens is present but abnormal.
Do not use for
Do not use H27.01 for pseudophakia, which means an intraocular lens is present after surgery. Do not apply it to unspecified aphakia or left-eye aphakia.
Coding tip
Confirm laterality in the operative note, assessment, or problem list before assigning H27.01.
