About coding dysmenorrhea

The ICD-10-CM code for dysmenorrhea is N94.6 (Dysmenorrhea, unspecified). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N94.6.

Within N94, choose N94.6 (Dysmenorrhea, unspecified) only when documentation doesn't support a more specific option: Mittelschmerz (N94.0), dyspareunia (N94.1), vaginismus (N94.2), Premenstrual tension syndrome (N94.3), primary dysmenorrhea (N94.4), secondary dysmenorrhea (N94.5), other specified conditions associated with female genital organs and menstrual cycle (N94.8) and unspecified condition associated with female genital organs and menstrual cycle (N94.9).

Don't report N94.6 together with the conditions in its Excludes1 note: psychogenic dysmenorrhea (F45.8).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
