Question: North Carolina Subscriber Answer: In cases where subscribers don't send Pediatric Coding Alert their complete medical record dictation, our editors can't accurately determine which code from the 99211- 99215 range best suits their circumstances, so we simply use an "x" to fill in the final number in the code. Once you read your practitioner's documentation, however, you should be able to select the appropriate office visit code based on the documented history, exam, and medical decision-making.
