Q28: Other congenital malformations of circulatory system

Non-billable headerICD-10-CM

Q28 is a non-billable header ICD-10-CM code for other congenital malformations of circulatory system. 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 aneurysm NOS (Q27.8)
congenital coronary aneurysm (Q24.5)
ruptured cerebral arteriovenous malformation (I60.8)
ruptured malformation of precerebral vessels (I72.0)

Excludes2: not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

congenital peripheral aneurysm (Q27.8)
congenital pulmonary aneurysm (Q25.79)
congenital retinal aneurysm (Q14.1)

Other codes that can never be billed with Q28

Their own Excludes1 notes name this code, so the conflict is not listed above.
