Codes differ for certain providers when service is prolonged. When your PM practice sees a patient for an evaluation and management (E/M) service that’s longer than normal, there is a chance you have a prolonged services claim on your hand. Benefit: When you code prolonged services correctly, you might be able to add a code (or two) to your E/M claim. You need to remember, however, that not all prolonged services are created equal. Code choice for your practice’s prolonged services will depend on the type of provider performing the service. Check out this advice on getting your prolonged services coding right every time. Separate Types of Prolonged Services When you are coding for prolonged services in an office/outpatient setting, you’ll choose from the following codes: So, what’s the difference between +99354/+99355 prolonged services and +99415/+99416 services? “The difference between these two sets of codes for prolonged services would definitely be who provided the service,” explains Manny Oliverez, CPC, CEO of Capture Billing & Consulting, Inc., in South Riding, Virginia. “Codes +99354 and +99355 are for prolonged services by a physician or other qualified health care provider— such as a nurse practitioner or physician assistant,” says Kent Moore, senior strategist for physician payment at the American Academy of Family Physicians. “Codes +99415-+99416 are for clinical staff — such as a registered nurse [RN] or a licensed practical nurse [LPN]. One other difference is that +99354-+99355 includes both prolonged E/M and psychotherapy, whereas +99415-+99416 only references E/M.” You must report +99354 and +99355 for office/outpatient E/Ms that have “a time component, and the typical time of the E/M service code billed must exceeded by 30 minutes,” according to Melanie Witt, RN, CPC, MA, an independent coding expert based in Guadalupita, New Mexico. “With +99415 and +99416, a clinical staff member provides the service — but it must be reported with an E/M service that has a time component where the billing provider has billed the E/M service,” Witt continues. For this pair of prolonged service codes, you must exceed the E/M service time by 45 minutes before reporting them. Also: “The physician or NPP [nonphysician practitioner] must be present to provide direct supervision of the clinical staff” during +99415/+99416 encounters, Oliverez says. Remember Patient Contact, or Forget These Codes Also remember that +99354, +99355, +99415, and +99416 all require direct patient contact, reminds Oliverez. For prolonged services that occur before or after direct patient care, you’d use 99358 (Prolonged evaluation and management service before and/or after direct patient care; first hour) and +99359 (… each additional 30 minutes [List separately in addition to code for prolonged service]).
