Answer Key and Discussion

Question 1

  1. Incorrect: Code 73721 describes the study of only one joint.
  2. Correct: Since both procedures were medically indicated and performed, it is appropriate to code 73721 (MRI, lower extremity, any joint) twice. The rationale for coding 73721 twice is that the descriptor specifies "joint" not "joint(s)." A modifier should be used to designate to the payer that this is a separate and distinct service and not a duplicate charge.
  3. Incorrect: Without the use of a modifier on the second procedure code this would appear to be a duplicate charge submission to the payer.
  4. Incorrect: Code 73718 identifies an MRI of a non-joint of the lower extremity.
