ICD-10 Code H27.129 – Anterior dislocation of lens, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.129 – Anterior dislocation of lens, unspecified eye
What it is
This code identifies a lens that has moved forward from its normal position in the eye, affecting an unspecified eye. It reflects an anterior dislocation or displacement of the crystalline lens.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible lens displacement, blurred vision, eye pain, or secondary changes noted on exam, but you should code only what is documented.
When to use this code
Use this code when the provider documents anterior dislocation of the lens and does not specify right or left eye. It also fits cases where the lens is described as displaced forward, dislocated anteriorly, or similar wording. If the chart identifies a specific eye, use the laterality-specific code instead.
Do not use for
Do not use this code for posterior lens dislocation, subluxation without dislocation, or cataract alone. If documentation is unclear, check documentation before assigning the code.
Coding tip
Always verify both the direction of dislocation and laterality; unspecified eye codes should be used only when the record truly lacks eye-specific detail.
