Append
modifier 57 only on an E/M code that represents the decision to perform a
procedure with a 90-day global.
Correct
use of modifier 57 (decision for surgery) seems like a cake walk, but there are
unseen rules you need to know before you attach the modifier to one of your
claims. Differences in global period definitions and claims edits could invite
trouble. Know what need to know to avoid denials:
Variations in Payer’s Definition of
Global Period
Global
surgical packages describe all services integral to a procedure as described by CPT.
Different
payers have different definition of global period. CMS, along with most other
payers, assigns a procedure or service to one of the following types of global
surgical packages:
·
0-day: Just the day of the surgery is
part of the package
·
10-day: The day of surgery and 10 days
after the surgery – in total 11-day package
·
90-day: One day prior to the surgery,
the day of the surgery, and 90 days after the surgery – in total a 92-day
package
According
to Medicare, you should append modifier 57 only on an E/M code that represents
the decision to perform a procedure with a 90-day global.
What does it mean for your cardiology
practice? You
will find 90-day globals for procedures such as pacemaker insertion codes 33206 to 33208 or ICD insertion code 33249. Many of the commonly used procedures in cardiology such
as catheterizations, normally have a 0-day global. In those cases, modifier 57
is not applicable.
Medicare as well as CPT®
include, for their procedures with a 90-day global – the day of or day before
surgery. However, there are exceptions as other payers, including some of the
Medicaid programs, don’t include a day before surgery; as such the only thing
they are worried about is E/M on the same day as the surgery.
Be well-versed with payer rules: If you do not follow their billing rules, you
are most likely losing money by not billing for payable services. If you’re in
doubt, use CMS/CPT rules.
Good practice: The American Medical Association (AMA) suggests that you keep a
health insurer reference log where you can include the payer’s global period
definition. Additionally, you could arm your cardiology practice with the much-needed guidance – code and modifier usage advice, payer rules, global
days, and everything you need to stay on the correct side of your cardiology
