About N94.9
N94.9 is the ICD-10-CM diagnosis code for unspecified condition associated with female genital organs and menstrual cycle. It belongs to category N94 (pain and other conditions associated with female genital organs and menstrual cycle), block N80-N98 (noninflammatory disorders of female genital tract) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within N94, choose N94.9 (Unspecified condition associated with female genital organs and menstrual cycle) 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), dysmenorrhea, unspecified (N94.6) and other specified conditions associated with female genital organs and menstrual cycle (N94.8).
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.
It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 629.9 (unspecified disorder of female genital organs).
