Outpatient Procedure Grouper mapping update

We have updated codes for the Outpatient Procedure Grouper (OPG) mapping. The updated 2021 UnitedHealthcare OPG Exhibit is available at Select the dropdown for View Outpatient Procedure Grouper (OPG) Exhibits.

Expired codes

  • On Jan. 1, 2022, we’ll delete 30 OPG 0–10 codes that expire on Dec. 31, 2021
  • We’ll delete 16 OPG unlisted codes that are expired

Newly published codes

  • On Jan. 1, 2022, we’ll add 31 OPG 0–10 codes
  • We’ll add 27 OPG unlisted codes

There are no other grouper level assignment changes to existing codes.

We require the appropriate line-level CPT® Healthcare Common Procedure Coding System (HCPCS) code, in addition to the revenue code, when billing for outpatient procedures.
