While both ACA 6002 and ACA 6004 aim to promote transparency within the healthcare industry, they focus on different aspects. ACA 6002 (Sample Transparency) focuses on the financial relationships between healthcare providers and the industry, whereas ACA 6004 (Spend Transparency) specifically targets the distribution of drug samples by pharmaceutical companies. Sample Transparency requires reporting of payments and transfers of value, while Spend Transparency mandates reporting of drug sample information.
