Hey guys! I'm new to family practice coding but was wondering... A patient is seen by the nurse practitioner and the doctor comes in and gives the patient a joint injection. The sole reason for the visit was to receive the injection, so we made the EM code not billable because there was no other reason for the patient being there. We bill the visit under the nurse practitioner. Is this incorrect? The facility I work for has been doing this long before I came in. Should the doctor be receiving credit for doing the joint injection? I'm not sure if the NP isn't "allowed" to do the joint injections or just simply does not do them. Any ideas? Example of the visit codes are 99213 (Which we marked unbillable), CPT 20610 CPT J3301 x4. Just to get the whole picture. Thanks!
