When billing a bilateral injection and HCPCS J1040 with two units be sure to append the correct modifier or the total units billed on a single line of the claim, not to exceed the line MUE; to avoid a duplicate denial.

For example, HCPCS J1040 would require a modifier to be appended indicating it is a distinct/separate service (i.e., modifier 59/76/XS) if billed on two claim lines.

Note, this method can be used on other injectable drugs as well such as other steroids and hyaluronate medications.
