OCA study finds Monterey hospitals’ commercial prices far above peers; lack of competition cited

The Office of Health Care Affordability on Monday presented a new market study concluding that Monterey County hospitals charge commercial insurers substantially higher prices than comparable hospitals across California.

The study, prepared with outside analysts using CalPERS and Covered California claims, found Monterey ranks first in wage‑adjusted inpatient prices and fourth in outpatient prices after accounting for regional wage differences, patient age and case mix. Presenters said those high prices persist despite operating costs, nurse wages and commonly used quality measures that are similar to Bay Area peers.

“New hospital price analysis using data from CalPERS and Covered California show that Monterey County has the highest inpatient prices in California,” said Dan Arnold, one of the study’s presenters. The analysis examined common inpatient admissions and outpatient procedures and found many wage‑adjusted price measures in Monterey exceed Bay Area averages by double‑digit percentages.

OCA researchers and consultants considered several explanations. They reported little evidence that higher local operating costs, higher wages or superior outcomes explain the price gap. They also discussed the “cost‑shifting” hypothesis — that hospitals raise private prices to offset low public rates — but said empirical work does not support cost‑shifting as the dominant driver in this market. Instead, the consultants concluded that hospital market power, significant physician‑hospital consolidation and a small number of “must‑have” hospitals that insurers must include in networks are key.

“Hospital‑physician integration, geographic dominance and contracting practices channel patients to higher‑priced hospitals and sustain these high prices,” the report states.

Community and labor representatives told the board the findings reflect daily reality in Monterey County, where workers and employers say premiums, deductibles and coinsurance have risen to unaffordable levels. Several union speakers said members travel outside the county for routine care because in‑county prices and cost‑sharing are prohibitive.

Hospital officials disputed parts of the analysis at the meeting. A representative for the California Hospital Association said Monterey hospitals face Bay‑Area wage and cost pressures combined with a larger share of publicly insured patients, and characterized the report’s conclusions as incomplete. The hospitals’ representative urged further engagement before policy steps are taken.

Presenters outlined policy options to address high prices, noting trade‑offs. Spending‑target enforcement (already part of OCA’s toolbox) would require hospitals to manage growth in price and volume but is retroactive and does not directly cap existing price levels. Other options include commercial‑payment caps tied to a multiple of Medicare rates and hospital global budgets — approaches used or studied in other states — but both would require complex implementation and statewide or regional coordination.

Board members asked for additional analysis (for example, on system‑level costs and reserves) and emphasized the urgency of remedial options. The presentation followed months of public testimony from Monterey residents, labor unions and employers documenting affordability harms.

The board did not announce a final policy action at the meeting, but members signaled interest in pursuing measures that directly constrain hospital prices where market failure is evident. The office will publish the full report and continue stakeholder engagement before recommending specific enforcement steps.
