In the April 2004 Oncology Coding Alert, the article "Don't Shortchange Your Oncology Office $152 on Pump Refills" stated, "Make sure, however, that you attach modifier -GB (Claim being resubmitted for payment because it is no longer covered under a global payment demonstration), the MCM states."
The sentence should read, "Make sure, however, that you attach modifier -59 (Distinct procedural service)."
