State office says payer equity adjustment not warranted now; quality adjustment deferred pending more data

The Office of Healthcare Affordability told the California Healthcare Affordability Board on May 20 that analyses of payer enrollment and social‑risk data do not support an immediate equity‑based adjustment to payer spending‑target performance, and recommended postponing any quality adjustment to spending targets until additional data accumulates.

OKA staff presented a multi‑year analysis (2018–2023) using HPD (Healthcare Payments Data) and the CDC Social Vulnerability Index (SVI) to map member social risk across commercial, Medicare Advantage and medical managed‑care markets. Maggie Hydeman summarized the findings: payer SVI distributions vary across entities but are stable year‑to‑year; commercial plans generally enroll lower‑SVI members, medical managed‑care plans enroll a larger share of high‑SVI members, and Medicare Advantage enrollment is more evenly distributed.

Because the membership SVI mix is persistent year‑to‑year and literature shows an inconclusive relationship between social risk and short‑term spending growth, OKA recommended not applying an upfront equity adjustment to payers’ measured spending growth. Instead, staff recommended treating social‑risk shifts as a factor to consider during enforcement—i.e., allowing payers to explain whether increases in high‑SVI members materially drove excess spending during the PIP/enforcement review.

On quality adjustments, OKA cited mixed research on the cost–quality link and noted that its own TME program and the OKA quality/equity measure set are still young. The office recommended waiting about two years to collect more quality data (first OKA quality/equity reports anticipated in 2027) and to align benchmarking with sibling regulators (DMHC, HAI) before using quality performance to change spending‑target outcomes.

Board members generally supported continued work. Several urged transparency—unmasking payer names in future analyses—and asked OKA to focus analytic effort on whether high social risk is associated with faster year‑to‑year spending growth (not just level differences). Some members also recommended using the enforcement/PIP process to surface investments and to require entities that exceed targets to explain how any extra spending addresses social drivers of health.

OKA said it will continue engagement with experts and consultants, monitor sibling agencies’ measure‑work, and return to the board with additional analysis, including payer‑level and provider‑level (physician organization, hospital) SVI assessments.
