Track the work of all involved providers to report correctly. Concurrent care occurs when two physicians perform separate E/M services on the same patient on the same date of service. If the patient's condition warrants the care of two (or more) physicians, you'll both be able to code for individual E/M care based on encounter notes – provided that your claim is valid, medically necessary, and specialty-specific. There are several factors to consider before submitting these claims, particularly in regard to subsequent hospital care. Starting point: "Physicians can bill only one subsequent visit per day," Tamara Canipe, RN, clinical quality management coordinator with Palmetto GBA, reminded participants in a webinar on subsequent hospital care. She advises that you remember these five rules about billing more than one physician visit per day: Case in point: Many components play into whether concurrent care is permissible under subsequent hospital visits. "The carrier will decide if concurrent care is covered," Canipe says. However, if two different medical providers under different specialty codes see patients on the same day but for different conditions and offer different diagnoses with notes that explain the need for the visit, she suggests that both physicians handle the situation by claiming that they administered subsequent hospital care. Tip: On concurrent care claims, "be diligent in the reporting order of the diagnoses for each claim as well," recommends Suzan (Berman) Hauptman, MPM, CPC, CEMC, CEDC, medical coding director at ACE Med Group in Pittsburgh, Pa. Example: Let's say one physician is treating condition A, and the other is treating condition B, but condition C is underlying. When coding for concurrent care, "condition C should not be the primary diagnosis for either service. The documentation should clearly illustrate the physician's involvement with the patient, thus allowing for a clear illustration as to who is treating what [injury or illness]," continues Hauptman.
