PA, PB, PC: Preventable conditions modifiers

Provider preventable conditions are those serious medical mistakes that should never happen and thus are deemed “never events.”

Priority Health will not pay for preventable events that occur in the operating room. All services provided in the operation room or other healthcare setting when this medical error occurs are considered part of the event and therefore, not reimbursed.

PA – Surgical or other invasive procedure on wrong body part

PB – Surgical or other invasive procedure on wrong patient

PC - Wrong surgery or other invasive procedure on patient

Inappropriate use:

• Non-surgical and non-invasive CPT/HCPCS codes
