ICD-10 code for round ligament endometriosis

The ICD-10-CM code for round ligament endometriosis is N80.3C9 (Endometriosis of the uterosacral ligament(s), unspecified side, unspecified depth).

Within N80.3C, choose N80.3C9 (the uterosacral ligament(s), unspecified side, unspecified depth) only when documentation doesn't support a more specific option: the right uterosacral ligament, unspecified depth (N80.3C1), the left uterosacral ligament, unspecified depth (N80.3C2) and bilateral uterosacral ligament(s), unspecified depth (N80.3C3).

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.
