Aphakia, unspecified eye

This code signifies the absence of the natural crystalline lens of the eye, without specifying which eye is affected. This condition typically results from surgical removal of the lens, most commonly due to cataracts, or rarely from trauma or congenital absence. The absence of the lens significantly impairs the eye's ability to focus light onto the retina.

Use this code when documentation confirms aphakia but does not specify laterality (e.g., "aphakia present," "patient is aphakic"). This often occurs when the medical record is incomplete regarding the affected eye, or when the condition is bilateral and the provider has not specified laterality. Supporting documentation would include operative reports for cataract extraction, ophthalmology exam notes, or history and physicals indicating the absence of the lens.

• Avoid using this code if laterality (right, left, or bilateral) is documented; instead, select the more specific H27.01, H27.02, or H27.03.
• This code should be sequenced as a primary diagnosis when aphakia is the reason for the encounter, such as for fitting of aphakic contact lenses or spectacles.
• Do not confuse aphakia with pseudophakia (presence of an artificial intraocular lens), which is coded separately under H27.1-.
