Code Classification

  • Congenital malformations, deformations and chromosomal abnormalities
    (Q00-Q99)
    • Chromosomal abnormalities, not elsewhere classified
      (Q90-Q99)
      • Other sex chromosome abnormalities, female phenotype, not elsewhere classified
        (Q97)

Q97.8 is a billable diagnosis code used to specify a medical diagnosis of other specified sex chromosome abnormalities, female phenotype. 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.

Approximate Synonyms

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

  • Absence of sex chromosome
  • Distal Xq28 microduplication syndrome
  • Familial infantile gigantism
  • Gigantism
  • Hypersomatotropic gigantism
  • Sex phenotype-karyotype dissociation syndrome
  • X-linked acrogigantism due to Xq26 microduplication

Clinical Classification

Clinical Information

  • Gigantism

    the condition of accelerated and excessive growth in children or adolescents who are exposed to excess human growth hormone before the closure of epiphyses. it is usually caused by somatotroph hyperplasia or a growth hormone-secreting pituitary adenoma. these patients are of abnormally tall stature, more than 3 standard deviations above normal mean height for age.
  • Sotos Syndrome

    congenital or postnatal overgrowth syndrome most often in height and occipitofrontal circumference with variable delayed motor and cognitive development. other associated features include advanced bone age, seizures, neonatal jaundice; hypotonia; and scoliosis. it is also associated with increased risk of developing neoplasms in adulthood. mutations in the nsd1 protein and its haploinsufficiency are associated with the syndrome.

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • 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)

Q97.8 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.

    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Genetic Disorders

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs.

Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder.

You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

There are three types of genetic disorders:

  • Single-gene disorders, where a mutation affects one gene. Sickle cell anemia is an example.
  • Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed. Chromosomes are the structures that hold our genes. Down syndrome is a chromosomal disorder.
  • Complex disorders, where there are mutations in two or more genes. Often your lifestyle and environment also play a role. Colon cancer is an example.

Genetic tests on blood and other tissue can identify genetic disorders.
