We are in the process of collecting enough information to ask for increased reimbursement from CMS and other third-party payors. This requires invoices – not price schedules, letters, or statements – from HollisterStier. Please forward copies of 2017 and 2018 (dated after 4-1-18) invoices (for the same products; i.e., 2017 mixed vespid; 2018 mixed vespid) to us or fax to 847-427-9656 – Attn: Sue Grupe. By comparing the 2017/2018 invoices and showing the drastic increases in costs, we can support our request for an increase in reimbursement for venom extract.
