About coding ovary syndrome residual
The ICD-10-CM code for ovary syndrome residual is N99.83 (Residual ovary syndrome).
Within N99.8 (other intraoperative and postprocedural complications and disorders of genitourinary system), N99.83 is specifically for residual ovary syndrome. Related codes cover other intraoperative complications of genitourinary system (N99.81), postprocedural hemorrhage of a genitourinary system organ or structure following a procedure (N99.82), postprocedural hematoma and seroma of a genitourinary system organ or structure following a procedure (N99.84), post endometrial ablation syndrome (N99.85), intraoperative and postprocedural complications and disorders of breast (N99.86) and other postprocedural complications and disorders of genitourinary system (N99.89).
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.
