I have a question regarding when the doctor is providing services at the patient's private residence - Place of service code 12. However, when the doctor performs E/M services, shouldn't the procedure code correlate with the POS. For example, instead of using 99201 - 99215 (Office or Other Outpatient Services), the doctor should be using 99341 - 99350 (Home Services), correct? Also, does anyone know the insurance reimbursement difference between POS 11 as opposed to POS 12? Thanks!
