About coding pelvic fundus weak
The ICD-10-CM code for pelvic fundus weak is N81.89 (Other female genital prolapse).
Within N81.8, choose N81.89 (Other female genital prolapse) only when documentation doesn't support a more specific option: Perineocele (N81.81), incompetence or weakening of pubocervical tissue (N81.82), incompetence or weakening of rectovaginal tissue (N81.83), pelvic muscle wasting (N81.84) and cervical stump prolapse (N81.85).
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.
