I have just seen my first denial for a unilateral clubfoot Dx when treating the patient with Ponseti Method.  The denial states a mismatch Dx code for the procedure: essentially they are saying the Dx states right and you are billing bilaterally and the left has no Dx of clubfoot.  This has never been an issue in the past and I am wondering if anyone is seeing this type of denial.  I am arguing that is the contralateral, non-clubfoot, orthosis is required in the treatment using the Ponseti Method but they are not accepting this and sticking to policy.
