What modifier do you bill when a patient has two 36415 charges on the same DOS? Example: Patient has an imaging study that requires a creatinine level. We charge for the creatinine and the 36415. The patient has a follow up office visit on the same date and more lab is ordered (and can't be added on to the previous draw due to specimen type). Do we use a modifier 91, 59, or 76/77 for the second medically necessary draw? Note: I know some carriers will only pay for one but some will pay for multiple. Please advise.

The practitioner MUE value of CPT code 36415 is “4” units which means this code can be billed to a maximum of 4 units in a day. As your documentation states that 2 venipuncture was done to draw 2 blood samples on the same date of service. So, you can bill 2 units as 36415 x1 and 36415 with 76 modifier x1 on different claim lines.
Hope the provided information would be successful.
