UB04 Box 74 - Where do I add the Principal Procedure Code for an institutional claim?

For inpatient claims where a procedure was performed, the claim must include the procedure code(s) and dates on which they were performed. This field is not currently required on outpatient claims. Be sure to check the Medicare Claims Processing Manual for any updates.

DrChrono makes it easy to add this information to the claim. You can add 1 primary code (will print in box 74a) and up to 4 additional codes (will print in boxes 74b - 74e).
