Part 2 of 2 — Case Study: Navigating the Medicare Advantage Squeeze in Miami-Dade County
This case study contrasts two leading local Medicare Advantage PPO plans against a risk-mitigation strategy of maintaining Original Medicare paired with a High-Deductible Medicare Supplement Plan G (HDG). Given the volatility detailed in our macro analysis, this framework prioritizes minimizing financial risk exposure and containing long-term liability.
Core Benefits of Original Medicare + High-Deductible Plan G (HDG)
- Network freedom: Mary can consult any provider or hospital across the United States that accepts Original Medicare. There are no network tiering penalties or restrictive HMO/PPO provider boundaries. This matters in Miami-Dade because hospitals have already dropped multiple HMO/PPO contracts in 2025–2026.
- Elimination of prior authorizations: Unlike Medicare Advantage plans, which frequently require approval for diagnostic imaging, specialist visits, and advanced clinical procedures, Original Medicare allows immediate treatment as directed by medical professionals.
- How the deductible works: The 2026 HDG deductible is $2,950. Mary doesn’t pay 100% out of pocket before coverage begins — Original Medicare pays its standard 80% share for Part B services from day one. Mary only pays the remaining 20% coinsurance, which accumulates toward the $2,950 statutory limit.
Financial Comparison Across Utilization Scenarios
Scenario 1: Low Healthcare Utilization
If Mary has a healthy year, here’s how costs compare
| Cost Component | Company A PPO (In-Network) | Company B PPO (In-Network) | Original Medicare + Plan HDG |
|---|---|---|---|
| Annual Private Plan Premium | $744.00 ($62.00/mo) | $1,844.40 ($153.70/mo) | $922.92 ($76.91/mo) |
| Preventive Care | $0.00 | $0.00 | $0.00 |
| Primary Care Visits | $0.00 ($0 copay) | $0.00 ($0 copay) | $283.00 (Part B deductible) |
| Routine Labs | $0.00 | $0.00 | $0.00 |
| Total Expected Annual Out-of-Pocket* | $744.00 | $1,844.40 | $1,205.92 |
*Excludes the mandatory government Part B premium.
Scenario 2: Moderate Healthcare Utilization
If Mary needs moderate care — specialists, imaging, PT — the gap begins to widen
| Cost Component | Company A PPO (In-Network) | Company B PPO (In-Network) | Original Medicare + Plan HDG |
|---|---|---|---|
| Annual Private Plan Premium | $744.00 | $1,844.40 | $922.92 |
| Specialist Visits | $220.00 ($55 copay × 4) | $240.00 | $403.00 |
| Advanced Imaging (MRIs) | $300.00 ($150 copay × 2) | $150.00 | $240.00 |
| Physical Therapy | $255.00 ($85 copay × 3) | $120.00 | $60.00 |
| Total Expected Annual Out-of-Pocket* | $1,519.00 | $2,354.40 | $1,625.92 |
*Excludes the mandatory government Part B premium.
Scenario 3: Catastrophic Healthcare Utilization
If Mary experiences a major medical event, the structural differences become dramatic
| Cost Component | Company A PPO (In-Network) | Company B PPO (In-Network) | Original Medicare + Plan HDG |
|---|---|---|---|
| Annual Private Plan Premium | $744.00 | $1,844.40 | $922.92 |
| Inpatient Hospital Stay | $2,425.00 ($485/day, Days 1–5) | $1,750.00 | $1,736.00 (Part A deductible) |
| Maximum Out-of-Pocket Cap | $9,250.00 (in-network limit) | $6,750.00 (in-network limit) | $2,950.00 (hard statutory cap) |
| Total Worst-Case Annual Out-of-Pocket* | $9,994.00 | $8,594.40 | $3,872.92 |
*Excludes the mandatory government Part B premium.
Localized Analysis
In a worst-case medical year, Original Medicare + HDG saves Mary significantly compared to both PPO options:
Worst-Case Savings — Original Medicare + HDG vs. PPO Plans
- vs. Company A PPO: saves $6,121.08
- vs. Company B PPO: saves $4,721.48
As established in Part 1 of this series, private insurers are facing tighter margins due to v28 reclassifications and DOGE audit clawbacks — and they are passing these strains onto patients via higher maximum out-of-pocket caps.
While Company A exposes Mary to a $9,250 in-network ceiling (up to $13,900 combined out-of-network) and Company B limits her to $6,750 in-network, the statutory High-Deductible Plan G hard cap stands at $2,950. This creates a structurally stronger protective wall against unpredictable clinical diagnoses or acute trauma, without the hassle of referrals and out-of-network providers.
Strategic Recommendation
Forecasting future clinical utilization with perfect accuracy is impossible, and an unexpected catastrophic medical event can develop without warning at any point in a calendar year. Because of this, minimizing peak financial liability should remain the core objective.
The recommendation is to select Original Medicare paired with High-Deductible Plan G (HDG). This strategy establishes a predictable safety net by legally limiting annual medical out-of-pocket exposure to $2,950 — compared to the significantly higher exposure found in Company A ($9,250) and Company B ($6,750). This route also avoids the administrative burden of prior authorizations and the network limitations inherent to managed care PPO structures currently in flux across Miami-Dade County.
As a final reminder, regardless of whether this Medigap strategy or a private PPO plan is chosen, Mary must continue maintaining her Part B monthly premium payment directly to CMS.
