Medi-Cal UA and UB modifiers

The difference is based on the type of anesthesia used. There are rules under the "Supplies and Drugs" section.
If you have access to the Medi-Cal website you can find this information under "Approved Modifiers":
UA: Used for surgical or non-general anesthesia related supplies and drugs, including surgical trays and plaster casting supplies, provided in conjunction with a surgical procedure code.
UB: Used for surgical or general anesthesia related supplies and drugs, including surgical trays and plaster casting supplies, provided in conjunction with a surgical procedure code.
