Q55 — Other congenital malformations of male genital organs

Not billable

Is Q55 billable?

No — Q55 is a non-billable header code. Q55 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 18 billable codes beneath Q55.

Excludes1 — never code together

The conditions below can never be reported together with Q55 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Excludes1 — never code together — inherited from Q50-Q56

  • syndromes associated with anomalies in the number and form of chromosomes (Q90-Q99)

Excludes2 — not included here — inherited from Chapter 17

The conditions below are not part of Q55, but a patient may have both at the same time. When documentation supports it, Q55 and the excluded code may both be reported.
