Pt had an Austin Moore cemented hemiarthroplasty performed on right hip. As the dr was getting ready to take post-op x-rays, pt went into cardiac arrest. Chest compression started and a code was called, pt given epinephrine and dopamine. Taken to ICU intubated, hypoxia may have been 2-4 minutes. My question is.....besides the hemiarthroplasty, are there any more codes or modifiers I should use?
