Impairment ratings (IR) assess the severity of a disability and the degree to which an injured worker’s injuries will affect future job performance following an on-the-job injury or disease.
Z0759 - performed by the Level II-accredited authorized treating physician who is providing primary care for the injury
Z0760 - performed by a Level II-accredited physician who has not previously treated the injured worker for the injury
If a physician determines the injured worker is at MMI and has no permanent impairment, the physician should be reimbursed for the examination at the appropriate level of E&M service. The authorized treating physician managing the claim should complete the WC164 closing report.
The total fee includes the office visit, a complete history and physical examination, the medical records review, the MMI determination, the required measurements, and the WC164 closing report completion. It also includes using the report forms and indicating the tables used to determine the rating from the AMA’s Guide to the Evaluation of Permanent Impairment, Third Edition (revised).
Medical records that take longer than one hour to review require a separate report. The report must document each record reviewed, the record date and the specific details of the record. Extensive record reviews require prior authorization and are billed as a special report using code Z0755.
These items are not separately billed, as they are included in the IR:
Bills may be denied for incorrect billing when:
If an injured worker fails to attend an impairment rating appointment or if the physician is notified by the party of a canceled or rescheduled appointment five days or less from the appointment date, the physician can bill for one-half of the fee for the scheduled service. The physician should bill Z0764 and indicate the code corresponding to the scheduled service in Box 19 of the CMS-1500 form or electronic billing equivalent.
