About coding hymen cyst
The ICD-10-CM code for hymen cyst is N89.8 (Other specified noninflammatory disorders of vagina). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N89.8.
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.
