Patients must be seeking help with any of the following needs related to their diagnosis: • Accessing prescribed healthcare, including understanding their healthcare benefits • Issues related to their health insurance benefits, including denials of care, out-of-pocket costs, network issues, and insurance options • Financial concerns, including cost-of-living expenses and medical expenses • Practical needs, including transportation and nutritional needs • Assistance with filing an application for disability Since its inception, PAF has provided direct, sustained patient assistance to more than 1.7 million patients and touched many more through its website and outreach events. Amongst the more common issues that patients and caregivers call PAF for help with include the inability to afford transportation expenses, inability to afford rent/mortgage, inability to afford their co-pay for medications, and inability to afford utilities and resulting shut-off notices. PAF serves patients with numerous health conditions, the majority of which have some form of cancer. Non-cancer diagnoses included rare diseases, chronic and debilitating conditions, nervous system conditions, cardiovascular conditions and vascular disease, autoimmune diseases, and diabetes. PAF solicits and receives donations to its programs from a multitude of sources including government agencies, non-profit organizations and for-profit organizations in the healthcare sector, including pharmaceutical manufacturers and healthcare providers.
