A 66-year-old man with a history of hypertension and stage 4 chronic kidney disease was admitted to the hospital for acute pulmonary embolism and started on a heparin drip. It is day two of his hospitalization, and your colleague has billed 99233 based on the 54 minutes they spent in the care of the patient today. You are called as cross-cover that evening to help with an issue involving multiple supratherapeutic activated partial thromboplastin time values. You make calls to phlebotomy, make changes to the orders, counsel the patient, speak with the nurse, and document what you have done, taking a total of 15 minutes in this care.
What billing does this qualify for?
You can bill a prolonged services billing code 99418 (for non-Medicare patients) or G0316 (for Medicare patients). These codes can be used when the time for the care of the patient exceeds 15 minutes from the highest level of billing (by time). Thus, the minimum time needed for 99233 to be billed by time is 50 minutes, hence, 99418/G0316 can be used when the time exceeds 65 minutes for the calendar day in this case. You can add another such code if you exceed another 15 minutes for the calendar day (e.g., 80 minutes in this case). Each code grants you 0.61 work relative value units (wRVUs). (see Tables 1 and 2)
