Medical Coding

Answer: D - 99291 is the correct code for the first 30-74 minutes of evaluation and management of a critical care patient. 99292 is also correct because this is the “add on” code for each additional 30 minutes after the first 74 minutes. Code 99292 needs to be charged two times because this patient required 120 minute of care or two hours.
Code 99291 is incorrect by itself. Code 99292 is incorrect by itself and must be charged however many times is needed for every 30 minutes after the first 74 minutes.
