21 is for entering the ICD-9-CM diagnosis code(s) for the patient's condition.
You may list up to four diagnoses.
Code to highest level of specificity (that is, if the ICD-9 lists 4 digits, use 4 digits; if it lists 5, code 5 digits). For example, 724.4, 722.52. Claims with diagnosis codes not coded to the highest level of specificity will be returned as unprocessable.
You do not have to list a diagnosis code on the claim form for each region
of the spine adjusted. Claim form completion requires only one diagnosis code
per line. All proper diagnosis codes are to be entered in the patient’s
documentation, however.
