About coding hymen occlusion
The ICD-10-CM code for hymen occlusion is N89.6 (Tight hymenal ring). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N89.6.
Within N89 (other noninflammatory disorders of vagina), N89.6 is specifically for Tight hymenal ring. Related codes cover 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), Hematocolpos (N89.7), other specified noninflammatory disorders of vagina (N89.8) and noninflammatory disorder of vagina, unspecified (N89.9).
Don't report N89.6 together with the conditions in its Excludes1 note: imperforate hymen (Q52.3).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
