Code Classification

  • Congenital malformations, deformations and chromosomal abnormalities
    (Q00-Q99)

      • Turner's syndrome
        (Q96)

Q96.9 is a billable diagnosis code used to specify a medical diagnosis of turner's syndrome, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

This code is applicable to female patients only. It is clinically and virtually impossible to use this code on a non-female patient.

Unspecified diagnosis codes like Q96.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Congenital anomaly of endocrine ovary
  • Genetic mosaic
  • Gonadal dysgenesis
  • Gonadal dysgenesis with auditory dysfunction, autosomal recessive inheritance
  • Monosomy X
  • Mosaic Turner syndrome
  • Ovarian dysgenesis
  • Turner syndrome

Clinical Classification

Clinical Information

  • 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.

  • Diagnoses for females only - The Medicare Code Editor detects inconsistencies between a patient’s sex and any diagnosis on the patient’s record, these edits apply to FEMALES only .

Present on Admission (POA)

Q96.9 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Patient Education


Turner Syndrome

What is Turner syndrome?

Turner syndrome is a genetic disorder that affects a girl's development and appearance. It can also cause health problems such as infertility and heart problems.

What causes Turner syndrome?

Turner syndrome happens because of a problem with a chromosome. Chromosomes are tiny "packages" in your cells that contain your genes. Genes carry information, called DNA, that controls what you look like and how your body works. Normally, girls receive one X chromosome from each parent. Turner syndrome happens when one of the X chromosomes is partially or completely missing.

What are the symptoms of Turner syndrome?

Turner syndrome can cause many different symptoms. The symptoms may be mild for some people. But for others, Turner syndrome can cause serious health problems.

Some of the symptoms of Turner syndrome affect a person's appearance. Most people with Turner syndrome are shorter than average. They may also have physical features such as:

  • A neck that is short and has extra skin (a "webbed" neck)
  • A low hairline in the back
  • Low-set ears
  • Swollen hands and feet

People with Turner syndrome may be born with heart and kidney defects. They usually don't have typical sexual development and are infertile. They are also at risk for other health problems such as high blood pressure, type 2 diabetes, osteoporosis, and thyroid problems.

How is Turner syndrome diagnosed?

Health care providers diagnose Turner syndrome based on symptoms and a genetic blood test called a karyotype test. Sometimes it is found in prenatal testing.

What are the treatments for Turner syndrome?

There is no cure for Turner syndrome, but there are treatments for some of the symptoms:

  • If they are started in early childhood, hormone injections can often increase adult height by a few inches
  • Estrogen replacement therapy (ERT) can help start sexual development. It also protects against bone loss
  • Assisted reproduction technologies can help some women with Turner syndrome get pregnant

People who have Turner syndrome need regular health checks. It's also important for them to have a care team that includes specialists who can treat the health problems caused by Turner syndrome.

Turner syndrome

Turner syndrome is a chromosomal condition that affects development in people who are assigned female at birth. Females typically have two X chromosomes, but in individuals with Turner syndrome, one copy of the X chromosome is missing or altered.

The most common feature of Turner syndrome is short stature, which becomes evident by about age 5. Reduced functioning of the ovaries, the female reproductive organs that produce egg cells (oocytes) and female sex hormones, is also very common. The ovaries develop normally at first, but egg cells usually die prematurely and most ovarian tissue breaks down before birth. 

Many affected individuals do not undergo puberty unless they receive hormone therapy, and most are unable to become pregnant naturally. A small percentage of people with Turner syndrome retain normal ovarian function through young adulthood.

About 30 percent of individuals with Turner syndrome have extra folds of skin on the neck (webbed neck), a low hairline at the back of the neck, puffiness or swelling (lymphedema) of the hands and feet, skeletal abnormalities, or kidney problems. One-third to one-half of individuals with Turner syndrome are born with a heart defect, such as a narrowing of the large artery that leaves the heart (coarctation of the aorta) or abnormalities of the valve that connects the aorta to the heart (the aortic valve). Complications associated with these heart defects can be life-threatening.

Most people with Turner syndrome have normal intelligence. Developmental delays, nonverbal learning disabilities, and behavioral problems are possible, although these characteristics vary among affected individuals.
