We are doing split billing. Our clinics are owned by the inpt facility and have a POS of 22.
Therefore, when a patient is seen we bill Part B & Part A for each service. On 12/8 our oncologist saw the patient in the clinic for 174.9 Malign Neoplasm breast NOS.
However, on 12/9 our cardiologist admitted the patient for Aortic Valve Disorder 424.1, Plerural Effusion 511.9 & Hyposmolatity 276.1.

What modifier do I use on the 12/8 E/M to denote is was separate from the INPT admit?

Again this is for the PART A facility billing.
