ICD-10 Code H27.123 – Anterior dislocation of lens, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.123 – Anterior dislocation of lens, bilateral
What it is
H27.123 identifies anterior dislocation of the crystalline lens in both eyes. The lens has moved forward from its normal position, usually into the anterior chamber or toward it.
Clinical signs
Clinical features vary; refer to documentation. Common findings include decreased vision, eye pain, glare, and an abnormal lens position on eye examination.
When to use this code
Use this code when the provider documents bilateral anterior lens dislocation or bilateral lens luxation with forward displacement. It may follow trauma, zonular weakness, or other ocular disease, but you should code only what is documented. If laterality is explicitly bilateral, select this code rather than an unspecified or unilateral lens-dislocation code.
Do not use for
Do not use this code for posterior lens dislocation, subluxation, or cataract without documented dislocation. Check documentation if the note only states “lens abnormality” or “displaced lens” without clear anterior bilateral involvement.
Coding tip
Confirm both laterality and direction of displacement in the ophthalmology note before assigning H27.123.
