Clinical InformationClinical

  • Noonan Syndrome

    a genetically heterogeneous, multifaceted disorder characterized by short stature, webbed neck, ptosis, skeletal malformations, hypertelorism, hormonal imbalance, cryptorchidism, multiple cardiac abnormalities (most commonly including pulmonary valve stenosis), and some degree of intellectual disability. the phenotype bears similarities to that of turner syndrome that occurs only in females and has its basis in a 45, x karyotype abnormality. noonan syndrome occurs in both males and females with a normal karyotype (46,xx and 46,xy). mutations in a several genes (ptpn11, kras, sos1, nf1 and raf1) have been associated the ns phenotype. mutations in ptpn11 are the most common. leopard syndrome, a disorder that has clinical features overlapping those of noonan syndrome, is also due to mutations in ptpn11. in addition, there is overlap with the syndrome called neurofibromatosis-noonan syndrome due to mutations in nf1.

  • 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.

Questions About Q96.8Overview

Is Q96.8 (Turner's syndrome) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other variants of Turner's syndrome on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does Q96.8 group to?

When other variants of Turner's syndrome is the principal diagnosis on an inpatient stay, it groups to MS-DRG 742, 743, 760, 761, with relative weights from 0.5696 to 1.8348 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q96.8 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for other variants of Turner's syndrome on inpatient claims.

What is the ICD-9 equivalent of Q96.8?

Under the General Equivalence Mappings, other variants of Turner's syndrome converts to ICD-9-CM 758.6 (gonadal dysgenesis). The mapping is approximate, so confirm the match fits the documentation.
