What MS-DRG does Q53.112 group to?

When unilateral inguinal 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 Q53.112 exempt from POA reporting?

Can Q53.112 be reported with a code from E34.5?

Not as a rule. The Excludes1 note at block Q50-Q56, which applies to Q53.112, 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).
