Q89.2
Congenital malformations of other endocrine glands
Q89.2 (also written Q892) is a billable ICD-10-CM diagnosis code for congenital malformations of other endocrine glands. It is part of the FY2027 code set, effective October 1, 2026. It is one of the 10 codes in category Q89 (Other congenital malformations, not elsewhere classified). The Alphabetic Index lists it under 62 entries. Its coding notes include 2 Excludes1 entries and 1 Excludes2 entry.
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.
Excludes2
Not included here. Both codes may be reported if the patient has both conditions.
