"The careful and proper usage of modifier -22 (Unusual procedural services) can be an invaluable tool in obtaining additional reimbursement for surgical services," says Arlene Morrow, CPC, CMM, CMSCS, a coding specialist and consultant with AM Associates in Tampa, Fla. But, coders, beware: Overuse of this modifier may be a red flag to carriers monitoring claims coded for the purpose of obtaining improper payment, she warns.
CPT guidelines indicate that "when the service(s) provided is greater than that usually required for the listed procedure, it may be identified by adding modifier '-22' to the usual procedure code." And convincing the carrier that a procedure was "greater than that usually required" is crucial for claims with modifier -22, because when approved, these claims will yield additional reimbursement in many cases an additional 20 to 25 percent more than their standard payment.
Morrow recommends developing "written policies and procedures for consistent coding and documentation application" as your standard plan of attack when submitting claims with modifier -22. Be sure your plan contains these five elements:
1. Develop an 'Unusual' Argument
CPT designed modifiers to represent the extra physician work involved in performing a procedure because of extenuating circumstances present in a patient encounter. Modifier -22 represents those extenuating circumstances that don't merit the use of an additional or alternative CPT Code , but instead raise the reimbursement for a given procedure, says Cheryl A. Schad, BA, CPCM, CPC, owner of Schad Medical Management in Mullica, N.J.
For example, a patient presents for an MRI of the brain with an MRI of the internal auditory canals. According to the AMA CPT information Services, when an MRI of the brain is performed without contrast material and the radiologist also visualizes the internal auditory canals by taking extra views of that, you should report 70551-22 (Magnetic resonance [e.g., proton] imaging, brain [including brain stem]; without contrast material), says Deepa Malhotra, MS, CPC, president of Healthcare Educational Resource Service Inc. in Aurora, Ill.
Most carriers including Medicare subscribe to the policy that unusual operative cases can result from the following circumstances outlined by The Regence Group, a Blue Cross Blue Shield association:
excessive blood loss for the particular procedure
presence of an excessively large surgical specimen (especially in abdominal surgery)
trauma extensive enough to complicate the particular procedure and not billed as additional procedure codes
