Are you reporting Level I modifiers when Level II modifiers may provide more specificity?
Did you know there are two levels of modifiers?
Both levels of modifiers further define services reported with CPT or HCPCS codes and do not change the CPT/HCPCS code description.
Level I CPT modifiers are developed by AMA, and CMS develops level II HCPCS modifiers.
HCPCS Level II modifiers may be appended to CPT codes, and CPT Level I modifiers may be appended to HCPCS Level II codes.
Let’s focus on the Level II HCPCS Modifiers, specifically, the anatomic modifiers.
Coronary artery modifiers
LC – Left circumflex coronary artery
LD – Left anterior descending coronary artery
LM – Left main coronary artery
RC – Right coronary artery
RI – Ramus intermedius coronary artery
Eyelid modifiers
E1 – Upper left eyelid
E2 – Lower left eyelid
E3 – Upper right eyelid
E4 – Lower right eyelid
Finger modifiers
FA – Left hand thumb
F1 – Left hand second digit
F2 – Left hand third digit
F3 – Left hand fourth digit
F4 – Left hand fifth digit
F5 – Right hand thumb
F6 – Right hand second digit
F7 – Right hand third digit
F8 – Right hand fourth digit F9 – Right hand fifth digit
Toe modifiers
TA – Left foot great toe
T1 – Left foot second digit
T2 – Left foot third digit
T3 – Left foot fourth digit
T4 – Left foot fifth digit
T5 – Right foot great toe
T6 – Right foot second digit
T7 – Right foot third digit
T8 – Right foot fourth digit
T9 – Right foot fifth digit
Coronary artery modifiers
LC – Left circumflex coronary artery
LD – Left anterior descending coronary artery
LM – Left main coronary artery
RC – Right coronary artery
RI – Ramus intermedius coronary artery

Laterality modifiers
LT – Left side of the body
RT – Right side of the body
I find that we sometimes default to modifier 59 or XS, but included in the definition of modifier 59 (X-), is the statement, “when another already established modifier is appropriate, it should be used rather than modifier 59. Only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used”.
Check your major payers’ policies. Most payers are consistent with CMS correct coding guidance. They require anatomical modifiers that identify the area or part of the body for procedures performed on the eyelids, fingers, or toes.
