H02.212 Cicatricial lagophthalmos right lower eyelid

ICD-10-CM Code H02.212: Cicatricial lagophthalmos right lower eyelid

ICD-10-CM code H02.212 identifies a diagnosis of cicatricial lagophthalmos affecting the right lower eyelid. This active terminology record is classified as a disease or syndrome and falls under the broader parent concept of cicatricial lagophthalmos. Clinical literature associates eyelid malpositions with ocular surface damage and visual compromise. 1 2

Plain-language overview

Code H02.212 designates a specific disease or syndrome concept for cicatricial lagophthalmos of the right lower eyelid, providing a standardized diagnostic label for clinical and administrative health records. 1

What this code represents

The diagnosis H02.212 represents an active terminology concept that is a narrower descendant of the parent concept H02.21, which broadly groups cicatricial lagophthalmos conditions. 1

Clinical context

Lagophthalmos is described as the inability to completely close the eye, and structural alterations like cicatricial changes can exacerbate exposure-related damage and ocular surface instability. 2 5

Cicatricial lower eyelid malpositions can lead to functional disruptions including exposure keratopathy, conjunctival inflammation, chronic dry eye disease, and impaired lacrimal drainage resulting in epiphora. 2

Coding details

The code H02.212 provides specific laterality and anatomic detail for the right lower eyelid, whereas the parent code H02.21 groups records related to cicatricial lagophthalmos without this specific distinction. 1 6

Documentation considerations

The broader parent code H02.21 may be used when a clinician documents cicatricial lagophthalmos in a patient's medical record, serving as a grouping entry for related diagnostic conditions. 6

Coverage and utilization context

A payer policy describes medical necessity requirements for eyelid reanimation procedures to treat lagophthalmos, but this clinical policy does not guarantee coverage for any specific diagnosis code. 5

What the sources add

While the terminology record defines the diagnostic code structure, clinical literature outlines associated anatomical and functional disruptions, and payer policies establish separate medical necessity criteria for corrective procedures. 1 2 5

A phecode mapping resource lists various unspecified and cicatricial lagophthalmos diagnoses by eye, but it does not provide the specific right lower eyelid detail established by the H02.212 terminology record. 1 3
