H21.4: Pupillary membranes

H21.4 is a non-billable header ICD-10-CM code for pupillary membranes. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • congenital pupillary membranes (Q13.8)

Inclusion terms

Excludes2 inherited from the categories above H21.4

Not part of this code, but both may be coded when both are present.
