About coding menstrual disorder
The ICD-10-CM code for menstrual disorder is N92.6 (Irregular menstruation, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N92.6.
Within N92, choose N92.6 (Irregular menstruation, unspecified) only when documentation doesn't support a more specific option: excessive and frequent menstruation with regular cycle (N92.0), excessive and frequent menstruation with irregular cycle (N92.1), excessive menstruation at puberty (N92.2), Ovulation bleeding (N92.3), excessive bleeding in the premenopausal period (N92.4) and other specified irregular menstruation (N92.5).
Don't report N92.6 together with the conditions in its Excludes1 note: lengthened intervals or scanty bleeding (N91.3-N91.5) and shortened intervals or excessive bleeding (N92.1).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
