Hematosalpinx

This code signifies the presence of blood within the fallopian tube. It indicates an accumulation of blood, often due to conditions like ectopic pregnancy, endometriosis, or pelvic inflammatory disease, causing distension of the tube.

Apply this code when documentation explicitly states hematosalpinx, hematocele of the fallopian tube, or blood within the oviduct. This diagnosis is typically made via imaging studies (e.g., ultrasound, MRI) or during surgical exploration.

• Ensure the documentation clearly specifies blood within the fallopian tube, not just general pelvic hemorrhage.
• Review the Excludes1 notes carefully to avoid co-coding with hematocolpos, hematometra, or tubal pregnancy, as these are mutually exclusive.
• Code any underlying cause of the hematosalpinx, such as endometriosis or pelvic inflammatory disease, as an additional diagnosis.
