Question: New York Subscriber Answer: Under these circumstances some Medicare carriers may require unlisted code 99499 (Unlisted evaluation and management service) and request to see all of your physician's documentation. Then, the carrier will pay as they see fit based on your documentation. Other Medicare carriers and commercial and private carriers might allow you use 99307 (Subsequent nursing facility care per day, for the evaluation and management of a patient ...) as you suggested. For example, the WPS Medicare website states that you can bill a subsequent nursing facility code "if documentation and medical necessity do not meet the requirement for billing an initial nursing facility care code."
