Best bet: Follow local guidance until more detailed info comes from Medicare. That interpretation basically says "that if you don't meet the initial care code, you have to bill unlisted, but the next day if you don't meet the initial care code you still can't bill a subsequent visit because you haven't billed an initial hospital care code, so you have to bill another 99499," the caller said. "I understand you're working on creating guidance on this issue, but what do we do today?" A CMS representative advised the caller to follow local contractor guidance until CMS is able to issue a more detailed update. "We've been working closely with the medical community to try to develop very clear instructions for how to address this particular situation as well as some other questions that have come to us, and we are very close to having that information completed," the representative said. "We want to be very sure when we're putting out information that we're putting it out only one time and that it's understood by everyone -- so that should be coming out very soon.." When asked whether the guidance would be issued in "days, weeks, or months," the CMS rep responded only that CMS is doing the best it can "to get it out as soon as possible."
