The Principal, US Market Access & Reimbursement Strategy works upstream and day to day with Clinical Affairs, Regulatory Affairs, HEOR, Medical Affairs, Business Development, and R&D to define the optimal reimbursement pathway for each platform from first-in-human through launch readiness, and to ensure that clinical study design and regulatory strategy are built with that pathway in mind - weighing trade-offs across coding, coverage, and payment options, and advising senior leaders on the risks, sequencing, and decisions needed to reach commercial viability. It requires deep working knowledge of the US reimbursement environment: CPT, HCPCS, and ICD-10 coding at a certified coder''s level; Medicare coverage and payment methodologies (OPPS, MPFS, IPPS); innovative payment pathways including NTAP, TPT, and NT-APC; provider economics across sites of service, including hospital margin, physician economics, and quality-linked payment programs; and early commercial payer strategy.
