About coding skin scar endometriosis
The ICD-10-CM code for skin scar endometriosis is N80.6 (Endometriosis in cutaneous scar).
Within N80 (endometriosis), N80.6 is specifically for endometriosis in cutaneous scar. Related codes cover of uterus (N80.0), of ovary (N80.1), of fallopian tube (N80.2), of pelvic peritoneum (N80.3), of rectovaginal septum and vagina (N80.4), of intestine (N80.5), other endometriosis (N80.8), unspecified (N80.9) and 4 more.
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 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
