I work for a Pediatrics office. Our charge entry person keeps adding -53 to screening codes like: 99173, 92551... Is this acceptable? the notes might say the child didn't know shapes or letters or refused to stand there and look at the chart for the vision screening or wouldn't stay still for the pure tone hearing screen. I've worked with family practice for a very long time and we would not charge for the screen since it couldn't be conducted, but would be notated on the chart. My research keeps telling me that those codes are for diagnosis and/or surgical services/procedures, no where says its ok for screening services. Some guidance please. Thank you.
