Turner's syndrome (Q96) ICD-10-CM
The Q96 code range covers turner's syndrome with 8 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the Q96 range.
Turner Syndrome
A syndrome of defective gonadal development in phenotypic females associated with the karyotype 45,X (or 45,XO). Patients generally are of short stature with undifferentiated GONADS (streak gonads), SEXUAL INFANTILISM, HYPOGONADISM, webbing of the neck, cubitus valgus, elevated GONADOTROPINS, decreased ESTRADIOL level in blood, and CONGENITAL HEART DEFECTS. NOONAN SYNDROME (also called Pseudo-Turner Syndrome and Male Turner Syndrome) resembles this disorder; however, it occurs in males and females with a normal karyotype and is inherited as an autosomal dominant.
About the Q96 Code Range
Turner syndrome involves underdeveloped reproductive organs in females and is associated with a 45,X chromosome pattern.
The subdivisions distinguish karyotypes, or chromosome patterns. Q96.0 identifies 45,X. Q96.1 and Q96.2 distinguish other specified patterns. Q96.3 and Q96.4 describe mosaicism, with different chromosome patterns in different cell lines. Q96.8 identifies other variants, while Q96.9 leaves the variant unspecified.
