This question is for cruiser or others who may have worked in the rating area. How will total hip replacements be rated? Will the surgery be rated as a whole or will it be rated for the prostestic parts that had to be replaced? Also what is considered residuals, screws, hematoma, or what, i am not sure? i read in one of the manuals that they rate for cracked fermora, nonunion loose stems??? I did not understand..Then i read somewhere they rated hips on flexion, i am not sure which way they are going to rate total hips replacements.
