About coding vulvar vestibulitis
The ICD-10-CM code for vulvar vestibulitis is N94.810 (Vulvar vestibulitis).
Within N94.81 (vulvodynia), N94.810 is specifically for vulvar vestibulitis. Related codes cover other vulvodynia (N94.818) and unspecified (N94.819).
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 757 (Infections, Female Reproductive System with MCC, relative weight 1.4649), DRG 758 (Infections, Female Reproductive System with CC, relative weight 0.9908) and DRG 759 (Infections, Female Reproductive System without CC/MCC, relative weight 0.7691), 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.
