[Solved]: Patient had undergone cardiac transplantation about…

Patient had undergone cardiac transplantation about 3 years prior. Upon coming to the ED this occasion it was for a three-day history of right lower quadrant pain. The white blood cell count was elevated, and a small-bowel X-ray examination showed some dilated small bowel loops but no free air. He was admitted, and an abdominal gastrointestinal ultrasound showed a mass measuring about 5 by 5 by 4 centimeters, which was presumed to be an appendiceal cyst. He underwent an ultrasound-directed percutaneous right lower quadrant aspiration; only a few drops of material were collected for diagnostic examination. Blood cultures were sterile, leukocytosis improved, and he remained afebrile with gradually decreasing pain. He was discharged on antibiotics and was to return in a few weeks for an interval appendectomy. ICD-10-CM code(s): ICD-10-PCS code(s): Rationale:
