What type of reference material is available to determine how a modifier will effect payment when used with a certain CPT code?
The Medicare Physician Fee Schedule Database (MPFSD) is published by CMS and updated annually. MPFSD has a list of indicators that reflect how claims are processed. All CPT/HCPCS codes subject to MPFSD indicators are provided in this database. The indicators will show whether or not a specific modifier can be used with a certain code and how the modifier will effect reimbursement. MPFSD also contains information regarding the appropriateness of billing for a co-surgeon for certain CPT/HCPCS codes. The MPFSD can be accessed at http://www.cms.hhs.gov/physicianfeesched.
