P83.5 vs Q55
P83.5 (Congenital hydrocele) compared with Q55 (Other congenital malformations of male genital organs), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. Q55 carries an Excludes1 note covering P83.5: “congenital hydrocele (P83.5)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
