About coding sacral nerve roots endometriosis
The ICD-10-CM code for sacral nerve roots endometriosis is N80.D2 (Endometriosis of the sacral nerve roots).
Within N80.D (endometriosis of the pelvic nerves), N80.D2 is specifically for endometriosis of the sacral nerve roots. Related codes cover unspecified (N80.D0), the sacral splanchnic nerves (N80.D1), the obturator nerve (N80.D3), the sciatic nerve (N80.D4), the pudendal nerve (N80.D5), the femoral nerve (N80.D6) and other pelvic nerve (N80.D9).
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.
