ICD-10 code for vulva dystrophy

The ICD-10-CM code for vulva dystrophy is N90.4 (Leukoplakia of vulva).

Within N90 (other noninflammatory disorders of vulva and perineum), N90.4 is specifically for leukoplakia of vulva. Related codes cover mild vulvar dysplasia (N90.0), moderate vulvar dysplasia (N90.1), dysplasia of vulva, unspecified (N90.3), atrophy of vulva (N90.5), hypertrophy of vulva (N90.6), vulvar cyst (N90.7), other specified noninflammatory disorders of vulva and perineum (N90.8) and noninflammatory disorder of vulva and perineum, unspecified (N90.9).

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.
