H27.131 Posterior dislocation of lens, right eye

ICD-10-CM Code H27.131: Posterior Dislocation of Lens, Right Eye

ICD-10-CM code H27.131 identifies a posterior dislocation of the lens in the right eye. It is a billable, specific code valid for reimbursement. The code falls under the parent category H27.13 for posterior lens dislocations and is distinguished from codes for left eye or bilateral occurrences. 1 5 4

Plain-language overview

Code H27.131 represents a finding where the lens in the right eye has dislocated posteriorly, and clinical literature discusses posterior dislocation of a lens fragment as a complication during cataract surgery. 1 2

What this code represents

The terminology record assigns the preferred name posterior dislocation of lens, right eye to H27.131, classifies its semantic type as a finding, and lists its active parent concept as H27.13. 1

H27.131 is a billable, specific code valid for reimbursement, and its terminology record maintains an active status within the ICD-10-CM version 2026. 5 1

Coding details

Within the lens disorder hierarchy, H27.131 sits under H27.13 alongside distinct laterality codes for the left eye, bilateral eyes, and unspecified eye. 4

A Medicare billing and coding article for cataract extraction explicitly lists H27.131 for the right eye, directly adjacent to H27.132 for the left eye and H27.133 for bilateral cases. 3

Documentation considerations

The code tree provides separate posterior dislocation options for the right eye, left eye, bilateral eyes, and unspecified eye, allowing documentation to align with a specific laterality designation. 4

Clinical context

Clinical literature notes that posterior dislocation of a lens fragment can complicate cataract surgery, potentially leading to secondary issues like glaucoma, retinal detachment, or macular edema. 2

What the sources add

While the terminology record defines the code structure, the Medicare article places H27.131 within operational cataract surgery billing context, and the clinical commentary describes the surgical complication itself. 1 3 2

Coverage and utilization context

A Medicare cataract extraction billing article includes H27.131 in a list of diagnosis codes, providing operational context for how the code appears in payer documentation. 3
