Although specialty drug claims make up only a small portion of the number of total drug claims submitted under group benefit plans, specialty drugs make up an increasing amount of total drug claims and expenditure for employers and other sponsors of group benefit plans. In 2025, both Express Scripts Canada and TELUS Health reported an increase in specialty drug spending.
Express Scripts Canada reported an increase of 15.7% in the percentage of members making at least one claim for a specialty drug and a 9.3% increase in the percentage of claims for a specialty drug.
TELUS Health reported that specialty drugs made up 32.8% of the total eligible amount, resuming an upward trek from 31.2% in the previous year. This followed two years of no growth and even a slight decline in 2022.
The rising trend for specialty drugs can be explained by the increasing number of specialty drugs, and newly approved indications for drugs that target inflammatory, skin conditions, and cancer as well as the growing trends for TRIKAFTA, a high-cost drug for the treatment of cystic fibrosis. The rise in speciailty drug spending is concerning to payers, advisors, and plan sponsors, but it is not the only challenge in specialty drugs, where prior authorization is required. Practices and processes result in slow approval rates and added administration expenses from manual review. These need to be updated to deliver efficiencies. Vocal advocates of change include Simplify Prior Authorization and the Prior Authorization Framework and Accreditation (PAFA) Program.
The Simplify Prior Authorization initiative is an advocate for education about prior authorization (PA) and improvement in current prior authorization practices and processes.
