There are a couple of possibilities. Are you paper billing or submitting claims on their web site. The codes are usually 2 letter codes and vary from insurance co to insurance co. If no treatments or referrals were done at the well child check, the code for " no refferals done" or "available, but mot used" should be used. If the patient has a sick code associated with the well child check and is being treated, the code for "under treatment" should be used. If a sick child is encountered for the well child check that needs a referral the code for "referral done or referred to other provider" needs to be used. I am sorry, I do not know the codes off hand.
If you are doing paper billing the codes are usually in the 24 H box. Sometimes the codes are printed in large font and the scanner of the ins. co reads them wrong.
