Advanced Modifier Engine - New!

The Advanced Modifier Engine was designed by CGS to assist suppliers in billing proper Healthcare Common Procedure Coding Systems (HCPCS) codes and modifier combinations. The tool includes Durable Medical Equipment Prosthetics Orthotics and Supplies (DMEPOS) commonly billed HCPCS with billing scenarios. Based on the specific HCPCS entered and the billing scenario, the tool recommends modifiers for claim submission.
