ICD-10 Code H27.8 – Other specified disorders of lens (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.8 – Other specified disorders of lens
What it is
H27.8 identifies lens disorders that do not fit a more specific ICD-10 category. Use it when the documentation names an unusual or specified lens problem, but not cataract or another listed lens diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Lens disorders may be noted on eye exam by abnormal lens appearance, position, or clarity, but the exact finding should be stated in the record.
When to use this code
Use H27.8 when the ophthalmology note documents a specific lens disorder that is not otherwise classified in ICD-10-CM. It is appropriate when the provider clearly identifies the lens as the affected structure, but no more specific code applies.
Check the chart for the exact diagnosis wording and laterality if documented elsewhere. If the record only says “lens abnormality” without detail, you may need to query for clarification.
Do not use for
Do not use this code for cataracts or for lens disorders with a more specific ICD-10-CM code. If the documentation supports another lens diagnosis, code that condition instead.
Coding tip
Match the provider’s exact lens diagnosis to the most specific code available before defaulting to H27.8.
