ICD-10 Code H27.122 – Anterior dislocation of lens, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H27.122 – Anterior dislocation of lens, left eye
What it is
H27.122 identifies a lens that has moved forward into the anterior chamber of the left eye. Use it when the crystalline lens is displaced in front of its normal position.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include visible lens displacement, reduced vision, eye pain, or signs of ocular trauma or glaucoma risk.
When to use this code
Use this code when the provider documents anterior dislocation of the left lens, including traumatic or nontraumatic displacement if the record specifies the left eye. It also fits operative, ophthalmology, or emergency notes that clearly state the lens is anteriorly dislocated.
Do not use for
Do not use it for posterior lens dislocation, cataract alone, or unspecified lens dislocation. If the laterality or direction of displacement is not documented, check documentation.
Coding tip
Confirm both laterality and the direction of dislocation before assigning H27.122.
