Q96.9 is a billable ICD-10-CM diagnosis code for Turner's syndrome, unspecified. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 742 through 743, 760 through 761. The code is exempt from POA reporting. Coders also document this condition as congenital anomaly of endocrine ovary. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Chromosomal abnormalities.

Clinical InformationClinical

  • Gonadal Dysgenesis

    a number of syndromes with defective gonadal developments such as streak gonads and dysgenetic testes or ovaries. the spectrum of gonadal and sexual abnormalities is reflected in their varied sex chromosome (sex chromosomes) constitution as shown by the karyotypes of 45,x monosomy (turner syndrome); 46,xx (gonadal dysgenesis, 46xx); 46,xy (gonadal dysgenesis, 46,xy); and sex chromosome mosaicism; (gonadal dysgenesis, mixed). their phenotypes range from female, through ambiguous, to male. this concept includes gonadal agenesis.

  • Gonadal Dysgenesis, 46,XX

    the 46,xx gonadal dysgenesis may be sporadic or familial. familial xx gonadal dysgenesis is transmitted as an autosomal recessive trait and its locus was mapped to chromosome 2. mutation in the gene for the fsh receptor (receptors, fsh) was detected. sporadic xx gonadal dysgenesis is heterogeneous and has been associated with trisomy-13 and trisomy-18. these phenotypic females are characterized by a normal stature, sexual infantilism, bilateral streak gonads, amenorrhea, elevated plasma luteinizing hormone and fsh concentration.

  • Gonadal Dysgenesis, 46,XY

    defects in the sex determination process in 46, xy individuals that result in abnormal gonadal development and deficiencies in testosterone and subsequently antimullerian hormone or other factors required for normal male sex development. this leads to the development of female phenotypes (male to female sex reversal), normal to tall stature, and bilateral streak or dysgenic gonads which are susceptible to gonadal tissue neoplasms. an xy gonadal dysgenesis is associated with structural abnormalities on the y chromosome, a mutation in the gene, sry, or a mutation in other autosomal genes that are involved in sex determination.

  • Gonadal Dysgenesis, Mixed

    a type of defective gonadal development in patients with a wide spectrum of chromosomal mosaic variants. their karyotypes are of partial sex chromosome monosomy resulting from an absence or an abnormal second sex chromosome (x or y). karyotypes include 45,x/46,xx; 45,x/46,xx/47,xxx; 46,xxp-; 45,x/46,xy; 45,x/47,xyy; 46,xypi; etc. the spectrum of phenotypes may range from phenotypic female to phenotypic male including variations in gonads and internal and external genitalia, depending on the ratio in each gonad of 45,x primordial germ cells to those with normal 46,xx or 46,xy constitution.

  • 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.

  • 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.

  • Monosomy X

    a chromosomal abnormality consisting of the presence of one copy of the x chromosome and the complete absence of a second sex chromosome (x or y) in somatic cells.

  • Turner Syndrome|45,X Gonadal Dysgenesis|45,X0 Syndrome|45X Syndrome|Bonnevie-Ullrich Syndrome|Gonadal Dysgenesis|Monosomy X|Turner syndrome|Ullrich-Turner Syndrome

    a gonadal dysgenesis syndrome occurring in phenotypic females, characterized by the absence of a part or all of one of the sex chromosomes. signs and symptoms include short stature, webbing of neck, low-set ears, hypogonadism, and sterility.

Questions About Q96.9Overview

Is Q96.9 (Turner's syndrome) a billable code?

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

What MS-DRG does Q96.9 group to?

When Turner's syndrome, unspecified 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 Q96.9 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 Turner's syndrome, unspecified on inpatient claims.

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

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

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
