Questions About Q53.111Overview

What is the ICD-10 code for unilateral intraabdominal testis?

Is Q53.111 (Abdominal testis, unilateral) a billable code?

What MS-DRG does Q53.111 group to?

When unilateral intraabdominal testis is the principal diagnosis on an inpatient stay, it groups to MS-DRG 729, 795, 730, with relative weights from 0.2022 to 1.0553 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q53.111 exempt from POA reporting?

Can Q53.111 be reported with a code from E34.5?

Not as a rule. The Excludes1 note at block Q50-Q56, which applies to Q53.111, 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).
