Contusion of uterus, initial encounter

This code signifies a bruise or injury to the uterine tissue resulting from blunt force trauma, without a laceration or rupture. It indicates damage to the blood vessels within the uterine wall, leading to localized bleeding and swelling. This type of injury is typically non-penetrating and affects the integrity of the uterine muscle.

This code is appropriate for documenting uterine contusions identified after abdominal trauma, such as from a motor vehicle accident, a fall, or direct impact to the lower abdomen. It is used when imaging studies (e.g., ultrasound, CT scan) reveal evidence of uterine bruising without a more severe injury like a tear or perforation. This code is specifically for the initial presentation and treatment of the injury.

• Ensure documentation clearly specifies "contusion" and not a laceration or rupture, as those have different codes.
• Verify that this is the patient's first encounter for this specific injury to use the "A" (initial encounter) seventh character.
• Always code any associated external cause of morbidity (e.g., W18.0XXA for fall on same level) to provide a complete clinical picture.
