Why It Matters

The core challenge is straightforward: when Congress allowed enhanced ACA premium tax credits to lapse at the end of 2025, South Carolina's marketplace enrollees faced an average premium increase of $470 per year, with roughly 588,000 residents affected, according to public statements by members of Congress. For a dominant regional insurer like BCBS of South Carolina, that kind of enrollment disruption — driven entirely by federal policy — is precisely the kind of issue that motivates sustained federal lobbying activity. A legislative fix, such as reinstating enhanced subsidies, would stabilize the market the insurer depends on. The company's own public communications acknowledged that "several important regulatory and legislative changes" were on the horizon heading into 2026 open enrollment.

By the Numbers: Lobbying Disclosure Filing Breakdown

Blue Cross Blue Shield of South Carolina filed a lobbying disclosure filing for the first quarter of 2026, reporting $50,000 in federal lobbying activity through its retained firm, Due South Advocacy LLC. The filing arrives as the state's individual insurance market faces a 21 percent premium rate increase — one of the steepest in the country — following the expiration of enhanced Affordable Care Act subsidies at the end of 2025.

Over the prior four quarters — second quarter 2025 through first quarter 2026 — BCBS of South Carolina reported a combined $400,000 in federal lobbying expenditures: $200,000 through Due South Advocacy LLC and $200,000 through Alignment Government Strategies, at a consistent $50,000 per firm per quarter.

The current LDA filing, covering the first quarter of 2026, reflects no change in spending from prior quarters. The firm roster has also remained stable — no new firms were added and none were dropped. Due South Advocacy LLC is a boutique operation with just two clients on its books in the past year: BCBS of South Carolina and the Grand Strand Business Alliance. Alignment Government Strategies fields a larger team, with seven lobbyists consistently appearing across its filings for BCBS of South Carolina.

One notable gap: the first quarter 2026 federal lobbying registration from Due South Advocacy LLC lists no lobbyists by name and no specific issues lobbied — a departure from prior quarters, when the firm reported lobbying on "policy issues related to private health insurance, Medicare, Medicaid and TRICARE."

The Agenda

The current filing lists no specific issues and no legislation. In prior quarters, Due South Advocacy LLC described its work as covering "policy issues related to private health insurance, Medicare, Medicaid and TRICARE." Alignment Government Strategies described its work more broadly as "health-care issues."

Broader Context: A Volatile Federal Policy Environment

The backdrop for this lobbying activity report is significant. The expiration of enhanced ACA premium tax credits — first enacted under the American Rescue Plan and extended through the Inflation Reduction Act — created immediate market disruption at the start of 2026. A Congressional Research Service report flagged the impact on 2026 exchange premiums directly.

Members of Congress were vocal. Sen. Elizabeth Warren publicly stated that 588,000 South Carolinians faced premium doubling if Congress failed to act, and separately quantified South Carolina's average increase at $470. Sen. Dick Durbin wrote directly to Blue Cross Blue Shield entities asking what the credit expiration would mean for enrollees, characterizing the response as describing "devastation." Rep. Lauren Underwood cited a 27 percent rate increase by BCBS of Illinois as a direct consequence of Republicans declining to extend the credits — a pattern mirrored in South Carolina's own 21 percent rate hike.

On the South Carolina-specific front, Rep. Nancy Mace highlighted more than $200 million in rural health funding flowing to the state through federal legislation, while Sen. Tim Scott flagged an active measles outbreak in the state's Upstate region as recently as April 2026. A separate Senate Banking Committee communication noted that Sen. Scott was examining challenges facing South Carolina's insurance markets more broadly.

A federal HHS Office of Inspector General audit also found that BCBS of South Carolina had overstated its Medicare segment pension assets, adding a layer of federal regulatory scrutiny to the insurer's Washington calculus.

The Bottom Line

BCBS of South Carolina's federal lobbying activity has been steady and consistent — two firms, $100,000 per quarter, focused on health insurance, Medicare, Medicaid, and TRICARE. The first quarter 2026 congressional lobbying disclosure adds another $50,000 to that tally without signaling any strategic shift. What has changed is the policy environment around the insurer, which is now navigating the direct market consequences of Congress's failure to extend ACA subsidies — consequences that are playing out in South Carolina's premium rates and enrollment numbers in real time.
