Important Note:

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