    I am getting the same error and need to have someone explain it to me in English.  This error message is very unclear, confusing, and unactionable' - Rhonda, Brain Advances, 814.273.6668

    I am suddenly getting this rejection code on 3 clients that I have been billing for several years. They all have recently been moved from Optum to Idaho Blue Cross, however I have successfully billed for over a month. What am I missing to get this error and did I do something to cause this sudden change? Help Help!

    I have a claim that has rejected due to error (21) missing or invalid information.  I am not able to see what the error is. Nothing has changed I've been billing for this patient. Could I get more clarification on this matter?


    Thank you!!
