Endometriosis, site unspecified

This code represents the presence of endometrial tissue outside the uterus, where the specific anatomical location of these implants has not been documented. This condition can cause chronic pelvic pain, dysmenorrhea, dyspareunia, and infertility.

This code is appropriate when a diagnosis of endometriosis is confirmed, but the physician's documentation does not specify the exact site (e.g., ovaries, fallopian tubes, peritoneum). It should be used when the medical record simply states "endometriosis" without further anatomical detail.

• Avoid using this code if a more specific site of endometriosis is documented; always code to the highest level of specificity.
• Query the provider if the documentation mentions endometriosis but lacks site specificity, to determine if a more precise code can be assigned.
• This code is a residual category and should only be used when no other specific ICD-9-CM code for endometriosis applies.
