Don’t report another prolonged service until you read this. You’re probably aware that the E/M codes include time parameters – but what happens when your visit spans a time period that goes beyond those thresholds? Before you code your next prolonged E/M session, make sure you read this timely advice. Tip 1: Remember This Face-to-Face Rule You’re probably familiar with the four prolonged face-to-face care codes: You’re probably also aware that you’ll need to use +99354/+99355 when the direct patient contact is provided by “a physician or other qualified health care professional,” according to CPT® guidelines. But if you use +99415/+99416, you’ll need to document that the service was provided by clinical staff under the direct supervision of a physician or qualified health professional. Tip 2: Thresholds Key to Accurate Time Coding Second, you need to make sure you calculate time correctly and be aware of the different time thresholds. Prolonged time of less than 30 minutes for the physician codes or 45 minutes for the clinical staff codes is not separately reportable. This means you must be able to document an additional 30 to 74 minutes for +99354, an additional 45 to 74 minutes for +99415, and any additional time between 15 and 44 minutes with added units of +99355 and +99416. Under these circumstances, when you report prolonged services, your time documentation needs to be precise. It should include details of important clinical matters — what happened in that face-to-face encounter — and it should also support coding. Tip 3: Know How and When to Use Non-Face-to-Face Prolonged Codes You can also document services your provider performs when the patient is not present with two more codes: Per CMS, you can report 99358/+99359, providing you can document prolonged communication consulting with other health care professionals related to ongoing management of the patient, prolonged review of extensive health records, and diagnostic tests regarding the patient. And, per CPT® guidelines, the services must “relate to a service or patient where (face-to-face) patient care has occurred or will occur and relate to ongoing patient management.” The time thresholds, however, remain the same as the face-to-face prolonged care codes. So, you can use 99358 to document the 30 to 74 minutes of non-face-to-face care and report additional units between 15 and 44 minutes with +99359. The same rules as +99354/+99355 and +99415/+99416 apply, only you don’t have to substantiate direct patient contact. Tip 4: Use Prolonged Care Codes Sparingly You should only use prolonged service codes to document unusual circumstances that go above and beyond the typical or average time of the documented visit code. To do that, it is important that you record the times for these time-based codes in the medical record. It is also important to remember that prolonged care face-to-face codes cannot be used if the initial time assessed to the base code has not been met. For example, you would have to have 55 minutes at a minimum to bill a 99214 (25 minutes) with a +99354 prolonged care code for the additional 30 minutes.
