ICD-10 Code H27.02 – Aphakia, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.02 – Aphakia, left eye
What it is
Aphakia, left eye means the natural lens is absent from the left eye. You use this code when the documentation specifically identifies the left eye as aphakic.
Clinical signs
Clinical features vary; refer to documentation. Commonly, aphakia is identified by absent crystalline lens on exam, often with marked refractive error or visual blur.
When to use this code
Use H27.02 when the provider documents aphakia limited to the left eye, such as after cataract extraction or lens removal. Code it when the record clearly states the condition and laterality. If the note only says “aphakia” without eye laterality, check documentation.
Do not use for
Do not use this code for pseudophakia, where an intraocular lens is present. Do not assign it if the documentation does not confirm left-eye involvement.
Coding tip
Always verify laterality in the operative note, exam findings, or assessment before selecting H27.02.
