Bottom Line

The annual visit includes common screening and counseling services. Payers often deny these services due to minor, easily avoidable mistakes. Most of the denial objections include

  • Missing the designated ICD-10 codes that represent the service
  • Exceeding service frequency limits is a common reason for denials.
  • Although performing these services, it lacks documentation
  • Billing different combinations of services that the payer might not accept. That’s why….
  • Schedule and space services with patients to ensure proper timing.
  • Forming a simple Checklist of these services or creating timers on your EHR can be a HUGE help!
  • E/M visits with the Annual visit (using Modifier 25) must be distinct and significant. The E/M visit must demonstrate medical necessity, addressing a new or existing issue on the same day as the AWV.
