Hematometra

Hematometra refers to the accumulation of blood within the uterine cavity. This condition typically results from an obstruction of the cervical canal or vagina, preventing the outflow of menstrual blood. It can cause uterine distension, pelvic pain, and, if chronic, may lead to complications such as endometriosis or infertility.

This code is appropriate for documenting the diagnosis of blood retention within the uterus. It should be used when diagnostic imaging (e.g., ultrasound) or direct examination confirms the presence of blood in the uterine cavity due to an outflow obstruction. Documentation should clearly indicate the presence of hematometra as the primary finding or a significant co-morbidity.

• Always look for the underlying cause of the hematometra (e.g., cervical stenosis, imperforate hymen) and code it as a secondary diagnosis if identified.
• Differentiate from hematocolpos (blood in the vagina) or hematosalpinx (blood in the fallopian tube), which are distinct conditions.
• Ensure documentation specifies "hematometra" and not just "uterine distension" or "pelvic mass" without further clarification of contents.
