Endometriosis of ovary

This code signifies the presence of endometrial tissue abnormally located on or within the ovary. This ectopic tissue responds to hormonal fluctuations, leading to inflammation, pain, and potential cyst formation (endometriomas).

Apply this code when documentation explicitly states endometriosis affecting the ovary. This diagnosis is often made during laparoscopic examination, imaging studies (e.g., ultrasound, MRI), or based on clinical symptoms like pelvic pain and infertility in conjunction with suggestive findings.

• Differentiate from other ovarian pathologies like ovarian cysts (non-endometrioma) or neoplasms.
• Consider sequencing with codes for associated symptoms (e.g., chronic pelvic pain, infertility) if they are not integral to the endometriosis diagnosis.
• Ensure the medical record clearly specifies the ovarian involvement, as endometriosis can occur in various pelvic locations.
