Modifiers 2

The document discusses common CPT and HCPCS modifiers used to provide additional information about medical procedures and services. Modifiers provide details such as whether a procedure had both professional and technical components, was performed more than once or on both sides of the body, or was reduced or discontinued. Examples are given for over 20 common modifiers indicating circumstances like unusual procedures, multiple surgeons, or services by assistants or residents. Documentation requirements are noted for some state-specific modifiers.
