AN ACT to amend Tennessee Code Annotated, Title 4; Title 8; Title 10; Title 53; Title 56; Title 63; Title 68 and Title 71, relative to pharmacy benefits.
SB0420 revises Tennessee law governing pharmacy benefits and health plan cost-sharing. The bill adds definitions for “health plan,” “healthcare service,” “insurer,” and “third-party administrator” to the state’s pharmacy-benefit statute, then replaces the existing cost-sharing section with new rules for how enrollee payments are counted toward deductibles and annual out-of-pocket limits.
Under the bill, insurers must count cost-sharing amounts paid by the enrollee or paid on the enrollee’s behalf by another person when calculating the enrollee’s contribution to applicable cost-sharing requirements. The bill includes an exception for health savings account-qualified high deductible health plans so that the rule does not interfere with federal HSA eligibility, except for preventive care. It also provides that the annual federal cost-sharing limit applies to all healthcare services covered under a health plan issued in Tennessee, and it prohibits insurers, pharmacy benefit managers, and third-party administrators from using the availability or amount of manufacturer financial assistance or product assistance to set or condition health plan coverage terms.
The bill’s main legal effect is to amend Tennessee Code Annotated § 56-7-3205 and related definitions in § 56-7-3201, expanding state regulation of how pharmacy and health plan cost-sharing is administered. It would affect insurers, PBMs, third-party administrators, and enrollees in Tennessee health plans, especially those using copay assistance, coupons, or other third-party payments for prescription drugs. The bill applies only to health plans entered into, amended, extended, or renewed on or after January 1, 2026.
The overall sentiment in the available record appears neutral to supportive, but there is limited evidence of debate because no committee transcripts or vote history were provided. The structure of the bill suggests a policy goal of protecting consumers’ ability to use financial assistance and ensuring those payments count toward deductibles and out-of-pocket caps, while also preserving federal HSA rules. Because no recorded discussion is included, there is no documented opposition or amendment activity in the materials provided.
The most notable point of potential contention is the restriction on insurers, PBMs, and third-party administrators from considering manufacturer assistance when designing coverage or setting terms. Supporters would likely view this as a consumer-protection measure that prevents plans from penalizing patients who use copay assistance, while opponents may argue it could affect premium design, formulary management, or cost-control strategies. Another possible issue is the interaction with federal law, especially HSA-qualified high deductible health plans, which the bill addresses by carving out a federal-law-safe approach.
The bill amends Tennessee’s pharmacy-benefit and health-plan statutes by changing how cost-sharing is credited and by limiting how insurers, pharmacy benefit managers, and third-party administrators may use information about drug assistance programs. It would require covered payments made by or on behalf of an enrollee to count toward cost-sharing, subject to a federal HSA-related exception, and would extend annual out-of-pocket limit protections to all covered healthcare services. It also adds new statutory definitions and applies prospectively to health plans renewed or entered into on or after January 1, 2026.
The available materials show no recorded committee debate or votes, so there is no direct evidence of partisan or procedural controversy in the record provided. Based on the bill’s text, the measure appears intended as a consumer-protection and affordability bill, which generally suggests a favorable policy posture toward patients and enrollees. Any opposition would likely center on insurer and PBM administrative flexibility rather than on the bill’s stated consumer goals.
The primary point of contention is the prohibition on insurers, pharmacy benefit managers, and third-party administrators from factoring in prescription-drug financial assistance when setting or conditioning coverage terms. Supporters are likely to argue this prevents plans from discouraging the use of copay cards and similar assistance, while critics may say it interferes with benefit design and cost containment. A secondary issue is the bill’s interaction with federal HSA rules, since the bill must preserve eligibility for high-deductible health plans while still requiring cost-sharing credits in most other circumstances.
