The patient is a 50-year-old female who was previously treated by closed reduction and external fixation of a fracture of her right tibia, distal medial malleolus. During follow-up care, it becomes evident the fracture is not healing. X-rays demonstrate a nonunion of the right distal tibia. The patient is admitted for surgical repair of the nonunion. The surgery performed is an open reduction of the right tibia with bone grafting. Bone for the grafting is harvested from the patient’s left iliac crest. The distal medial malleolus tibial bone, at the site of the non-union, is osteotomized and repositioned. The harvested bone graft is packed into the fracture site to replace the missing bone, and three screws are inserted to secure the area. The patient is discharged the day after surgery for recovery at home. Note: List all applicable codes excluding the External Cause codes. Principal Diagnosis: Secondary Diagnoses: Principal Procedure: Secondary Procedure: Secondary Procedure: Hint: both the harvesting of the bone and the graft must be coded.

An 80-year-old male was brought to the emergency department (ED) by his family with the chief complaint of “nose bleed.” The patient is taking Coumadin under prescription by his internist for chronic atrial fibrillation. The patient is also known to have congestive heart failure. The patient said his nose began bleeding about two hours ago and he was unable to stop the bleeding with other methods he had used in the past. He reported that he had these nose bleeds before today. However, today the bleeding is more pronounced and could not be stopped at home. In the ED, the physician is able to control the bleeding somewhat but recognized that an ENT physician should be called in for consultation. The patient’s laboratory work revealed anemia and an EKG showed the existing atrial fibrillation. Because of his various conditions, his internist admitted him to the hospital. He was seen by the ENT physician, who was able to stop the bleeding with an anterior and posterior packing. The packing was removed on day two, and the epistaxis had stopped. Repeated laboratory work confirmed the physician’s diagnosis of “chronic blood loss anemia.” The patient continued to receive medications for the chronic atrial fibrillation,  HTN, and congestive heart failure, and new medications were started to treat the anemia. The patient’s Coumadin was continued, but the dosage was lowered. In the physician’s discharge progress note, he wrote “Epistaxis due to Coumadin therapy with resulting chronic blood loss anemia in a patient with chronic atrial fibrillation and congestive heart failure.” Principal Diagnosis: Secondary Diagnosis: Add’l Diagnosis: Add’l Dx: Add’l Dx: Add’l Dx: Add’l Dx: Procedure:
