ICD-10 code for primary dysmenorrhea

The ICD-10-CM code for primary dysmenorrhea is N94.4 (Primary dysmenorrhea).

Within N94 (pain and other conditions associated with female genital organs and menstrual cycle), N94.4 is specifically for primary dysmenorrhea. Related codes cover Mittelschmerz (N94.0), dyspareunia (N94.1), vaginismus (N94.2), Premenstrual tension syndrome (N94.3), secondary dysmenorrhea (N94.5), dysmenorrhea, unspecified (N94.6), 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).

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.
