About coding Perineocele
The ICD-10-CM code for Perineocele is N81.81 (Perineocele).
Within N81.8 (other female genital prolapse), N81.81 is specifically for Perineocele. Related codes cover incompetence or weakening of pubocervical tissue (N81.82), incompetence or weakening of rectovaginal tissue (N81.83), pelvic muscle wasting (N81.84), cervical stump prolapse (N81.85) and other female genital prolapse (N81.89).
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.
