These six levels are consistent with the American Society of Anesthesiologists (ASA) ranking of patient physical status. Physical status is included in the CPT codebook to distinguish among various levels of complexity of the anesthesia service provided.
Example: 00100-P1

Physical Status modifiers are represented by the initial letter ‘P’ followed by a single digit from 1 to 6 as defined in the following list:

P1: A normal healthy patient                

P2: A patient with mild systemic disease

 P3: A patient with severe systemic disease          

 P4: A patient with severe systemic disease that is a constant threat to life

P5: A moribund patient who is not expected to survive without the operation

P6: A declared brain-dead patient whose organs are being removed for donor purposes

Appropriate Usage

Inappropriate Usage

TIP: Medicare does not recognize Physical Status P modifiers.
