About coding Hydrocolpos
The ICD-10-CM code for Hydrocolpos is N89.8 (Other specified noninflammatory disorders of vagina).
Within N89, choose N89.8 (Other specified noninflammatory disorders of vagina) only when documentation doesn't support a more specific option: mild vaginal dysplasia (N89.0), moderate vaginal dysplasia (N89.1), dysplasia of vagina, unspecified (N89.3), leukoplakia of vagina (N89.4), stricture and atresia of vagina (N89.5), Tight hymenal ring (N89.6), Hematocolpos (N89.7) and noninflammatory disorder of vagina, unspecified (N89.9).
Don't report N89.8 together with the conditions in its Excludes1 note: current obstetric trauma (O70.-, O71.4, O71.7-O71.8) and old laceration involving muscles of pelvic floor (N81.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for N89.8)
