Q27.8
Other specified congenital malformations of peripheral vascular system
Q27.8 (also written Q278) is a billable ICD-10-CM diagnosis code for other specified congenital malformations of peripheral vascular system. It is part of the FY2027 code set, effective October 1, 2026. It is one of the 12 codes in category Q27 (Other congenital malformations of peripheral vascular system). The Alphabetic Index lists it under 97 entries. Its coding notes include 1 Excludes1 entry and 6 Excludes2 entries.
Guidelines tip
From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.
Chapter 17 codes can be used for life. Manifestations that are an inherent part of a specifically coded anomaly are not coded separately. A corrected malformation is reported with a personal history code.
Excludes1
Not coded here. The listed conditions generally should not be reported together.
- arteriovenous malformation (Q27.3-)
Excludes2
Not included here. Both codes may be reported if the patient has both conditions.
Also from chapter/block level (1 note)
- inborn errors of metabolism (E70-E88)
