New Endometriosis ICD Codes for 2023
New Endometriosis ICD codes for 2023 (effective Oct 1, 2022)
Previously, the codes for endometriosis were limited. The codes did not specify side, depth of invasion or associated symptoms. As you might imagine, our understanding and classification of this disease has changed and thus our coding of the disease needed changing as well. The inadequate current coding for endometriosis is in the N80 set as follows:
N80 Endometriosis
N80.0 Endometriosis of uterus
N80.1 Endometriosis of ovary
N80.2 Endometriosis of fallopian tube
N80.3 Endometriosis of pelvic peritoneum
N80.4 Endometriosis of rectovaginal septum and vagina
N80.5 Endometriosis of intestine
N80.6 Endometriosis in cutaneous scar
N80.8 Other endometriosis
N80.9 Endometriosis, unspecified
AAGL and Endometriosis leaders petitioned for new ICD-10 CM codes to represent our increased understanding. These codes were approved by the American Medical Association, Centers for Medicare & Medicaid Services, and the World Health Organization and will go into effect October 1, 2022. The codes further define laterality and depth of invasion as well as more specifically identify the location. Thus, the above 10 codes have expanded to 168 codes.
In general, the codes start with identifying the side of the lesions (right, left, bilateral), the depth of the lesion (unspecified depth, superficial, deep) and then sorted by location (ovary, tube, cul-de-sac, sidewall, brim, uterosacral ligament, rectovaginal septum, intestine, scar, bladder, ureter, diaphragm, thoracic cavity, abdominal wall {not in a scar} and finally, specific affected nerves).
The AAGL recently held a webinar titled “New Endometriosis ICD-10 Codes Overview.” If you missed the opportunity to attend, the webinar is now available to AAGL members by clicking the image below.

Using the new codes more specifically will allow for better research and understanding of endometriosis and hopefully better treatment options and outcomes for this challenging disease.

Happy coding.
