How a Boston Law Firm Cut 37% on Health Insurance — Walking Away From a +9.37% MGB Renewal and an About-to-Sign #1 PEO
Company Profile: An 11-employee Boston-area law firm, all subscribers enrolled on the firm's group plan. Currently on Mass General Brigham Health Plan, Complete HMO HSA $2,500 deductible. Mid-renewal cycle when a +9.37% rate increase hit on the comparable plan for the April 2026 plan year — and the firm was within days of signing with ADP TotalSource (the #1 PEO in the US by market share) before the broker pulled them to a second PEO quote that changed the math.
The renewal trap that almost cost this firm $446K over six years
- +9.37% MGB renewal on a comparable plan. The Mass General Brigham renewal for the 04/01/2026 plan year landed at $13,934.93/mo ($167,219/yr) on the Complete HMO HSA $2,500 30/45/450 — up from $12,740.90/mo. Two buy-down options softened the increase: HSA 3000 (+7.27%) or HSA 3600 (+2.75%). Both kept the firm on the same HMO network with a worse plan design.
- About to sign with the #1 PEO. The firm was days away from executing an ADP TotalSource contract. ADP is the largest PEO in the US by market share — the default "safe" answer most brokers and CFOs default to. The comparable ADP HPHC HMO quote came in at $155,256 Y1: marginally better than the MGB renewal, but still HMO-network, and locking the firm into a multi-year PEO bundle without a second-opinion quote.
- HMO referral gates. The MGB HMO required PCP-routed referrals for specialist visits, which the firm's attorneys flagged as a daily friction. A PPO with direct specialist access was a quality-of-life upgrade the team wanted but the previous broker hadn't priced.
- Renewal-curve trend with no horizon math. Small-group fully-insured carriers in Massachusetts run 7–12% annual increases; MGB's eight years on file averaged 8%. A single year of "we'll just absorb this renewal" compounds. Without a 6-year cost trajectory next to a 6-year alternative cost trajectory, the firm couldn't see what staying actually cost.
- No real comparison shopping. The renewal had been "shop the same MGB plans + maybe a Blue Cross quote" each year. The PEO + Cigna alternative wasn't on the table until a second broker (Valerie Smith) reframed the question from "which MGB plan?" to "which funding structure entirely?"
What the firm actually needed (versus what the renewal was offering)
- Year-1 premium materially below the MGB renewal trajectory — not a 2–9% softening of a known-bad path
- PPO network with direct specialist access (no HMO referral gates) and broader hospital coverage than the MGB HMO offered
- A multi-year cost trajectory the principals can model: a single quote in isolation hides what compounding does, especially against an 8%/yr commercial trend
- Second-opinion PEO quote before committing to the first PEO bid. ADP TotalSource is a respectable choice; it shouldn't be the only one priced.
- Ancillary lines (dental, vision, EPLI, LTD, STD, life) priced as a coordinated stack rather than year-by-year retail, where the PEO bundle creates real volume leverage
- Onboarding by 04/01/2026 (the MGB plan-year boundary) so there's no gap and no double-coverage
Six options modeled: stay on MGB, two buy-downs, two PEO routes, and Prestige + Cigna
1. Stay on MGB Complete HMO HSA $2,500 (accept the +9.37% renewal)
Projected cost: $167,219 Y1 health-only ($13,934.93/mo). Same network, same plan design — just more expensive.
Limitations: 8%/yr is the MGB historical trend; over six years, the $167K Y1 compounds to $245K by Y6, $1.23M cumulative. No structural change, no improvement, just bigger checks each April.
✗ Pure inertia — accepts the worst-case trajectory2. MGB Buy-Down #1 — Complete HMO HSA 3000 35/55 Enhanced FlexRx
Projected cost: $13,667.25/mo ($164,007/yr), a +7.27% increase vs current.
Trade-off: Deductible bumps from $2,500 to $3,000 (aggregate). Saves the firm ~$3,200/yr Y1 versus the comparable plan, but employees absorb $500 more in first-dollar exposure. Same HMO referral gates, same network, same 8%/yr trend.
✗ Worse plan design for marginal premium relief3. MGB Buy-Down #2 — Complete HMO HSA 3600 35/55 Enhanced FlexRx
Projected cost: $13,090.76/mo ($157,089/yr), only +2.75% vs current.
Trade-off: Deductible jumps to $3,600 — that's $1,100 more out-of-pocket exposure per employee than today. Inpatient copay also doubles to $1,000. The premium near-flat looks attractive in isolation; net employee cost rises materially when you account for first-dollar usage.
◐ Premium flat-ish, but employees pay the rest4. ADP TotalSource PEO + HPHC HMO (the about-to-sign deal)
Projected cost: $155,256 Y1 health-only.
Why the firm was about to sign: ADP TotalSource is the largest PEO in the US — the safe-by-reputation default. The HPHC HMO inside the bundle priced marginally below the MGB renewal. PEO bundles HR + payroll + ancillary so the firm gets one vendor and one monthly invoice.
Why it didn't survive a second-opinion bake-off: Still HMO-network. PEO commitment is multi-year and exit-friction-heavy. Renewal trend inside an ADP bundle tracks the underlying carrier (HPHC), which has its own 8%/yr trend baked in. And — critically — the firm never priced a second PEO.
◐ Beats the MGB renewal by ~$12K Y1, but locks in HMO + #1-PEO default5. MGB HMO HSA inside a PEO wrapper
Projected cost: $132,545 Y1 health-only.
Assessment: A creative middle path — keep the existing MGB plan but route it through a PEO admin layer to access bundled pricing on payroll + ancillary. The Y1 number is genuinely competitive. But the firm wanted a network upgrade out of HMO, which this option doesn't deliver, and the renewal trend still rides MGB's 5–8% history.
◐ Strong cost, but doesn't solve the HMO-network ask6. Prestige PEO + Cigna $1,500-Deductible PPO ✓ Selected
Projected cost: $109,135 Y1 health-only — 37% below the MGB comparable-plan renewal.
Network: Cigna national PPO. Direct specialist access, no HMO referral gates, wider hospital coverage than the MGB HMO including Boston-area providers the firm's attorneys specifically requested.
Deductible: $1,500 individual — actually lower than the MGB $2,500 the firm was already paying. Plus higher-tier Cigna $0-Deductible and $3,500-Deductible options were modeled in parallel for the firm to see the trade-space.
PEO structure: Prestige PEO handles benefits + payroll + ancillary bundling. A second PEO quote alongside ADP TotalSource was the critical move that revealed the price spread — without it, the firm would have signed ADP at $155K Y1 (vs $109K on Prestige + Cigna) and never known the $46K/yr gap existed.
Ancillary: Dental ($301/mo), EPLI ($1,000/mo), LTD ($250/mo), STD ($192/mo), Life ($165/mo) — all priced as a coordinated stack inside the Prestige bundle rather than year-by-year retail.
Onboarding: Live by 04/01/2026, aligned with the MGB plan-year boundary.
The 6-year math: $446,100 cumulative savings on health insurance alone
The reason the Prestige + Cigna route wins isn't only the Year-1 price tag — it's that the spread compounds against the MGB trend. Year-1 quotes had Prestige + Cigna PPO at $109,135 vs. $167,219 for the MGB comparable-plan renewal — a $58,084 Year-1 gap. Both trajectories modeled at the same 8%/yr commercial small-group trend (so the absolute spread widens, but the percentage savings stays constant). The cumulative gap reaches $446,100 over six years:
| Year | MGB Comparable Renewal @ 8%/yr | Prestige + Cigna PPO @ 8%/yr | Cumulative savings |
|---|---|---|---|
| Year 1 | $167,219 | $109,135 | $58,084 |
| Year 2 | $180,597 | $117,866 | $120,815 |
| Year 3 | $195,044 | $127,295 | $188,564 |
| Year 4 | $210,648 | $137,479 | $261,733 |
| Year 5 | $227,500 | $148,478 | $340,755 |
| Year 6 | $245,700 | $160,355 | $426,100 |
| 6-yr total | $1,226,708 | $780,608 | $446,100 saved |
Adding the equivalent ancillary stack (payroll/admin, WC, dental, EPLI, LTD, STD, life) to both sides, the 6-year totals come in at $1,335,544 (MGB renewal path) vs. $989,228 (Prestige + Cigna PPO) — the absolute savings narrows slightly because the ancillary lines apply to both columns, but the 37% Y1 health-insurance savings remains the dominant lever. The Prestige PEO bundle also folds in PEO-grade pricing on EPLI ($1,000/mo with 6-year discounting), LTD, STD and life that retail-quoted separately would each carry their own margin loads.
Year-1 figures from the Mass General Brigham renewal proposal (January 2026 run date) and the Prestige PEO + Cigna PPO $1,500-deductible quote modeled for the same 11-employee enrollment census. Both columns trended at 8%/yr representative for MA small-group commercial health insurance. Ancillary lines (dental, WC, EPLI, LTD, STD, life) applied equally to both columns where applicable.
The Honest Trade-Offs of Switching to Prestige + Cigna PPO
The Prestige + Cigna structure isn't free of trade-offs. We surface them upfront so the firm goes in with eyes open:
- Payroll moves to Prestige. PEO structures involve co-employment for tax and benefits purposes. The firm's existing payroll provider relationship ends; Prestige becomes the payroll-of-record. For an 11-employee law firm without dedicated HR headcount, this is operationally a wash — one fewer vendor to manage — but it is a real switch.
- $1,500 PPO deductible (vs. $2,500 on the current MGB HSA). The Cigna deductible is actually lower than the firm's current plan, but the plan-design comparison is different (PPO with copays vs. HSA-compatible with high deductible). Some employees who had built up HSA balances under MGB may prefer to keep the HSA-eligible deductible structure; modeled comparable Cigna $3,500-deductible HSA-compatible options are available if that preference emerges in enrollment.
- Network change. Cigna national PPO is broader than MGB HMO overall, but the specific Boston-area specialist mapping needs verification before open enrollment — a few high-utilization MGB-network specialists may need to be confirmed in-network on Cigna PPO or the employee needs to be notified.
- Exit friction on the PEO bundle. Exiting Prestige in 3–5 years (if the firm grows past 50 employees and self-funding becomes the better destination) requires unwinding the payroll + ancillary stack as a coordinated event. Not impossible — the firm exits any PEO at the same friction — but the cost of getting out should be modeled at decision time, not at exit time.
- Renewal trend assumption. The 8%/yr trend used in the 6-year model is representative for MA small-group commercial; the actual Cigna renewal could come in materially below that in benign years or above in bad ones. The savings number is anchored on the Y1 quote spread; the compounding line is illustrative of trajectory, not a guarantee.
If any of those is a deal-breaker, the conversation stops at the quote stage — not at the employee surprise-bill stage.
Why Prestige PEO won the second-PEO bake-off versus ADP TotalSource
ADP TotalSource is a respectable choice. The firm was days from signing it. The reason Prestige PEO won the bake-off comes down to five things that don't usually surface in a single-PEO quoting process:
- Y1 health-insurance cost: $109,135 vs. $155,256 on ADP. A $46,121 single-year delta. Compounded at the same trend, ~$340K over six years.
- Cigna PPO vs. HPHC HMO. ADP's bundled medical was an HPHC HMO — same referral-gate friction the firm was trying to leave at MGB. Prestige paired with Cigna PPO, the network upgrade the firm wanted, at a lower price.
- Smaller-shop responsiveness. Prestige is a regional PEO with attentive client-success staffing. ADP TotalSource is a Fortune-150 operation; firms under ~25 employees often report being "lost in the queue" during renewal cycles. The firm's principals weighed this directly.
- No multi-year contract trap. ADP's standard PEO contract carries multi-year terms with material exit friction. Prestige offers an annual-renewal structure that lets the firm reconsider the relationship every year without breakage.
- The second-quote habit, baked in. The firm now has a calibrated baseline: ADP TotalSource at $155K vs. Prestige + Cigna at $109K. Next year's renewal conversation starts with two priced options, not one — the structural improvement is permanent.
Why the second-PEO quote saved this firm $446K
The Prestige + Cigna route won on three axes the about-to-sign ADP deal couldn't match together:
Why the Structure Won This Deal
1. Rates beat the field, including the about-to-sign #1 PEO. Year-1 quote came in at $109,135 on Prestige + Cigna PPO vs. $155,256 on the ADP TotalSource HPHC HMO deal the firm was days from signing — a $46,121 Year-1 gap. Against the stay-on-MGB-renewal trajectory ($167,219 Y1), Prestige + Cigna saves 37% in Year 1 alone, compounding to $446,100 over six years.
2. Network upgrade, not a step-down. Most cost-savings moves come with a network trade-off (HMO step-down, narrower hospital list, fewer specialists). This one went the other direction: HMO → PPO, with national Cigna PPO depth replacing MGB's regional HMO referral gates. The firm's attorneys specifically flagged HMO referral friction as a daily quality-of-life issue; the new structure removes it.
3. The second-PEO discipline becomes the firm's permanent habit. The single biggest structural change isn't this year's quote — it's that the firm now has two PEO quotes on file every renewal cycle. ADP TotalSource at $155K vs. Prestige + Cigna at $109K is the calibrated baseline. Whatever next April's renewal looks like, the firm starts the conversation with two priced options instead of one. That structural improvement compounds beyond the 6-year horizon.
The bottom line: The firm walked away from a +9.37% MGB renewal and an about-to-sign ADP TotalSource contract, and landed on Prestige PEO + Cigna $1,500-deductible PPO. The decision saved 37% in Year 1 on health insurance and projects to $446,100 in cumulative savings over six years — on a base of 11 employees. The plan went in force April 1, 2026, aligned with the MGB plan-year boundary.
