ICD-10 code for Metrorrhagia

The ICD-10-CM code for Metrorrhagia is N92.1 (Excessive and frequent menstruation with irregular cycle). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N92.1.

Within N92 (excessive, frequent and irregular menstruation), N92.1 is specifically for excessive and frequent menstruation with irregular cycle. Related codes cover excessive and frequent menstruation with regular cycle (N92.0), excessive menstruation at puberty (N92.2), Ovulation bleeding (N92.3), excessive bleeding in the premenopausal period (N92.4), other specified irregular menstruation (N92.5) and irregular menstruation, unspecified (N92.6).

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

In MS-DRG v44.0, it is part of the grouping logic for DRG 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC, relative weight 1.8456), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC, relative weight 1.2974), DRG 760 (Menstrual and Other Female Reproductive System Disorders with CC/MCC, relative weight 1.0129) and DRG 761 (Menstrual and Other Female Reproductive System Disorders without CC/MCC, relative weight 0.7041), in MDC 13 (Diseases and Disorders of the Female Reproductive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
