HB 2556 regulates healthcare transaction fees and facility charges by restricting the imposition of facility fees for telehealth and preventive health services. The bill requires healthcare providers to obtain and use a National Provider Identifier (NPI) on payment claims and mandates advance notification to patients regarding facility fees. It also prevents third-party payors from reimbursing facility fees unless the NPI is included. Violations result in administrative penalties of up to $1,000 per violation. The bill aims to increase transparency and prevent surprise billing for facility fees in healthcare settings​.
