ICD-10 Code H27.00 – Aphakia, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.00 – Aphakia, unspecified eye
What it is
H27.00 identifies aphakia when the lens is absent from an unspecified eye. Use it when the record states aphakia but does not specify right or left eye.
Clinical signs
Typical findings include reduced uncorrected vision, loss of lens function, and need for strong corrective lenses. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents aphakia without laterality or when the eye is not identified in the note. It may appear after cataract surgery, trauma, or lens removal, but you should code only what is documented. Check documentation if laterality is available elsewhere in the record.
Do not use for
Do not use H27.00 if the chart specifies right or left eye, since a laterality-specific code is more accurate. Do not use it for pseudophakia or other lens disorders.
Coding tip
If the note names the eye, choose the laterality-specific aphakia code instead of the unspecified code.
