CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

Q96 is a non-billable ICD-10-CM category code for Turner's syndrome, so it cannot be submitted on claims. Use a more specific code from this category instead, such as Q96.0, Q96.1, Q96.2, and Q96.3.

Specific Coding for Turner's syndromeOverview

Non-specific codes like Q96 require more characters. Use one of these billable codes instead:

  • Use Q96.0 for Karyotype 45, X

  • Use Q96.1 for Karyotype 46, X iso (Xq)

  • Use Q96.2 for Karyotype 46, X with abnormal sex chromosome, except iso (Xq)

  • Use Q96.3 for Mosaicism, 45, X/46, XX or XY

  • Use Q96.4 for Mosaicism, 45, X/other cell line(s) with abnormal sex chromosome

  • Use Q96.8 for Other variants of Turner's syndrome

  • Use Q96.9 for Turner's syndrome, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to Q96: its own notes plus those printed at block Q90-Q99 and Chapter 17. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Block Q90-Q99 Chromosomal abnormalities, not elsewhere classified applies to 74 codes
  • mitochondrial metabolic disorders (E88.4-)
From Chapter 17 (Q00-QA1) Congenital malformations, deformations and chromosomal abnormalities applies to 900 codes
  • inborn errors of metabolism (E70-E88)

Notes

Clinical InformationClinical

  • 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.

Patient EducationClinical

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.

Questions About Q96Overview

What is the ICD-10 code for Turner's syndrome?

Q96 is the ICD-10-CM category for Turner's syndrome, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

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

No. This is a category header that groups the codes for Turner's syndrome, and headers cannot be submitted on claims. Claims for Turner's syndrome need a more specific code from this category, such as Q96.0, Q96.1, and Q96.2.

Can Q96 be reported with Q87.19?

Not as a rule. The Excludes1 note on Q96 lists "Noonan syndrome (Q87.19)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
