CMS Pub. 100-02, ch. 15, § 20.2
Physician Expense for Allergy Treatment
B3-2005.2, B3-4145
Allergists commonly bill separately for the initial diagnostic workup and for the treatment (See §60.2).
Where it is necessary to provide treatment over an extended period, the allergist may submit a single bill for
all of the treatments, or may bill periodically. In either case the Form CMS-1500 claim shows the
Healthcare Common Procedure Coding System (HCPCS) codes and from and through dates of service, or
the Form CMS-1450 outpatient claim shows the HCPCS code and date of service (except for critical access
hospital (CAH) claims).
