Premera Asking for ICD / Diagnosis Codes

I’m a massage provider for Premera Blue Cross. This morning I was verifying massage therapy benefits for a patient when the customer service rep at Premera asked me for the diagnosis codes (ICD) from the doctor’s prescription. This is the first time I’ve had this happen. I don’t know whether I got a new customer service rep or whether they’re always supposed to have been asking for this or whether this is a change in the way they operate. In any case, it’s a good reminder to have all of the necessary information (CPT code(s), ICD code(s), treatment plan, statement of medical necessity, etc.) before beginning massage treatments for a new patient.
