The diagnosis is considered clinically impossible for a patient in the stated age.  Either the diagnosis or the age is considered inaccurate.

This edit identifies procedure codes that when coded twice, represent the same procedure performed on both of the same bilateral joints of the lower extremity.  Otherwise, a code edit will instruct the fiscal intermediary to verify that the two different procedures were performed on two different bilateral joints.  (MCE Edit 14).
