Specific code 2014 ICD-9-CM Diagnosis Code 758.6
Gonadal dysgenesis
  • Billable Code
  • ICD-9-CM 758.6 will be replaced by an equivalent ICD-10-CM code (or codes) when the United States transitions from ICD-9-CM to ICD-10-CM on October 1, 2015.
  • ICD-9-CM 758.6 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.
Clinical Information
  • 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.
  • A syndrome in which the affected patients have only 45 chromosomes, the loss of one of the x chromosomes producing an xo chromosome constitution. The syndrome occurs in 1/2500 female births and nearly 99% of xo fetuses are aborted. Gonadal agenesis and short stature are the main features in the surviving infants. Associated anomalies may included webbed neck, cubitus valgus, shield chest, short stature, lymphedema, coarctation of the aorta, pigmented nevi, and various renal, skeletal, dermatologic, neoplastic, and autoimmune complications. Mental retardation is attributed to ring chromosome x. The phenotype varies and not all abnormalities occur in all patients.
  • Abnormal development of a gonad (ovary or testicle). Men with gonadal dysgenesis have a greater risk of developing testicular cancer. Gonadal dysgenesis is usually part of a genetic syndrome.
  • Genetic disease that produces sterile females due to monosomy for x chromosome; the ovaries are rudimentary or missing; other abnormalities include short stature, webbed neck, and a broad chest with widely spaced nipples.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 758.6 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
