ICD-10 Code H27.11 – Subluxation of lens (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.11 – Subluxation of lens
What it is
H27.11 identifies partial displacement of the eye’s natural lens from its normal position. The lens remains in the eye, but its support is shifted or weakened, causing malposition.
Clinical signs
Findings may include blurred vision, lens decentration on exam, or visible edge of the lens in the pupil area. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents subluxation of the crystalline lens, whether traumatic or nontraumatic, and the provider names lens subluxation as the diagnosis. It may also apply when the note describes partial lens dislocation or lens instability. Check documentation if the record only mentions dislocation without specifying subluxation.
Do not use for
Do not use H27.11 for complete lens dislocation or for other lens disorders such as cataract or aphakia. If the chart is unclear, check documentation.
Coding tip
Capture laterality and any associated eye injury or cause when documented, because those details may require additional coding.
