- Could you please tell me which diagnosis code is invalid (If there are multiple DX code coded)
- Check patient payment history if the same DX code paid with same CPT
- IF Yes
- Ask for clarification from rep and send claim back for reprocessing

- IF No
- What is the time limit to send corrected claim?
- What is the Fax# or Mailing address to send an appeal?

Note:
- This denial should be assigned to coding team to review and provide correct dx code and once response received with correct dx details then send corrected claim to insurance by updating correct dx code even if the time limit to send correct claim is crossed.
- If coding team states that dx code is correct then send an appeal to insurance.
- When sending an appeal, calculate the time limit from denial date, if it is not crossed then send the appeal or else write off the claim if time limit is crossed.
- Sometimes client wants us to send the appeal even if time limit is crossed, so work accordingly.
