Deep endometriosis of bilateral ovaries

This code signifies the presence of deeply infiltrating endometrial tissue within both ovaries. This condition is a severe form of endometriosis where the endometrial-like tissue penetrates more than 5mm beneath the ovarian surface. It is often associated with significant pain and infertility.

Use this code when diagnostic imaging (e.g., MRI, transvaginal ultrasound) or surgical findings confirm deep endometriosis affecting both ovaries. Documentation should explicitly state "deep endometriosis" and specify bilateral ovarian involvement. This code is appropriate for patients presenting with chronic pelvic pain, dyspareunia, or infertility attributed to this specific condition.

• Ensure documentation differentiates between superficial and deep endometriosis; this code is only for deep infiltration.
• Verify bilateral involvement; separate codes exist for unilateral ovarian deep endometriosis.
• Consider sequencing this code after any codes for associated complications, such as ovarian endometriomas (N80.11-).
