Summary
Indiana Health Coverage Programs (IHCP) is implementing new dental coding requirements effective November 27, 2022, specifying which tooth numbers must be used with specific dental procedure codes across all managed care entities. Additionally, a claim processing issue for code D2943 has been corrected for dates of service from January 1, 2021 forward.
Action Required
By November 27, 2022: Billing team must update system to enforce specific tooth number requirements for 38 dental procedure codes as specified in the IHCP policy table. Update billing software validation rules to only accept the approved tooth numbers for each code (e.g., D3310 only accepts tooth numbers 6-11, 22-27). Train staff on new tooth numbering requirements and note that D1354 and D1355 require prior authorization for members 21 and older. Monitor for automatically reprocessed D2943 claims beginning December 7, 2022.
