Key Points and Billing Modifier Issues:

  • RCM Spotlight Consultants revealed discrepancies in modifier usage, leading to a better understanding of billing inefficiencies.
  • Certain modifiers like TA, T5, LT, LC, RT, F5, and F8 may not be required for infectious disease wound panels or pathology CPT codes.
  • The APF Handbook cautions against reporting modifiers such as modifiers such as TA-T9, FA-F9, E1-E4, AF, and ST for pathology and lab services without explicit instructions from health plans.
  • Stripping these modifiers and refiling claims that had been denied with a CO-4 denial reason could potentially unlock reimbursement opportunities of nearly $200,000.



Leveraging the robust capabilities of RCM Spotlight empowers healthcare organizations to optimize and take control of their revenue cycle management. Accurate modifier usage ensures streamlined billing processes, reduces denials, and unlocks the potential for increased revenue.
