Q50 is a non-billable ICD-10-CM category code for congenital malformations of ovaries, fallopian tubes and broad ligaments, so it cannot be submitted on claims. Use a more specific code from this category instead, such as Q50.01, Q50.02, Q50.1, and Q50.2.

  • androgen insensitivity syndrome (E34.5-)
  • syndromes associated with anomalies in the number and form of chromosomes (Q90-Q99)

Questions About Q50Overview

Is Q50 a billable code?

No. This is a category header that groups the codes for congenital malformations of ovaries, fallopian tubes and broad ligaments, and headers cannot be submitted on claims. Claims for congenital malformations of ovaries, fallopian tubes and broad ligaments need a more specific code from this category, such as Q50.01, Q50.02, and Q50.1.

Can Q50 be reported with a code from E34.5?

Not as a rule. The Excludes1 note at block Q50-Q56, which applies to Q50, lists "androgen insensitivity syndrome (E34.5-)". 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).
