ICD-10-CM Code H21.42
Pupillary membranes, left eye
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.H21.42 is a billable ICD code used to specify a diagnosis of pupillary membranes, left eye. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code H214 is used to code Persistent pupillary membrane
Persistent pupillary membrane (PPM) is a condition of the eye involving remnants of a fetal membrane that persist as strands of tissue crossing the pupil. The pupillary membrane in mammals exists in the fetus as a source of blood supply for the lens. It normally atrophies from the time of birth to the age of four to eight weeks. PPM occurs when this atrophy is incomplete. It generally does not cause any symptoms. The strands can connect to the cornea or lens, but most commonly to other parts of the iris. Attachment to the cornea can cause small corneal opacities, while attachment to the lens can cause small cataracts. Using topical atropine to dilate the pupil may help break down PPMs.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code H21.42 and a single ICD9 code, 364.74 is an approximate match for comparison and conversion purposes.
