Managed Care 13Fs: UNH, ELV, HUM, CI Post-v28 Repricing

The 2024 Medicare Advantage v28 risk-adjustment model changes reshaped institutional positioning across the four major US managed-care insurers: UnitedHealth Group (UNH), Elevance Health (ELV — formerly Anthem), Humana (HUM), and Cigna Group (CI). The v28 model tightened risk-coding-to-payment relationships, removing approximately $9-12 billion of industry-wide annual reimbursement. Companies with heavier Medicare Advantage exposure faced material profitability pressure; companies with diversified commercial-insurance plus Medicare-Advantage mixes faced less impact. The 13F holder books reflect the resulting active-manager repositioning. Dodge & Cox holds Humana at 1.08% portfolio in deep-value contrarian overweight. Wellington Management Group holds UnitedHealth at 0.91% portfolio. Capital World Investors holds UNH at 1.03% portfolio. Reading these positions requires understanding the v28 repricing context.

The 2024 Medicare Advantage v28 repricing

CMS finalized the v28 risk-adjustment model in 2023, with phased implementation starting 2024. The changes:

1. Tightened risk-coding-to-payment relationship. Higher diagnosis-coding intensity no longer translated as directly into payment increases.
2. Removed bonus payments for specific chronic conditions. Several diagnosis categories that had attracted reimbursement-optimization coding were de-emphasized.
3. Phased in across 2024-2026. Full v28 effect realized by 2026; insurers had multi-year window to reprice plans and adjust benefit design.

The combined effect removed approximately $9-12 billion of industry-wide annual reimbursement at peak. Humana — with Medicare Advantage representing over 50% of revenue — was the largest single relative loser. UnitedHealth, with broader commercial + Optum diversification, faced less direct impact (though still meaningful).

The institutional positioning by company

UnitedHealth Group (UNH)

Active managers held through the 2024 Change Healthcare cyber breach plus v28 repricing:

• Wellington Management Group at 0.91% portfolio.
• Capital World Investors at 1.03% portfolio.
• Citadel Advisors at 1.09% (options-paired exposure).
• Susquehanna market-maker inventory at 1.19% portfolio.

The institutional view treats UNH operational stress as transitory. Diversified Optum technology platform plus commercial insurance buffers v28 impact.

Humana (HUM)

Most active managers reduced positions through the 2024 stress; Dodge & Cox stands out as the value-discipline holder:

• Dodge & Cox at 1.08% portfolio — the value-discipline contrarian overweight.
• BlackRock at 0.03% portfolio — near-index weight, post-stress dilution.
• Vanguard sleeves at 0.03-0.05% portfolio weights.

HUM positioning is structurally underweight versus pre-stress levels. Dodge & Cox's overweight is the contrarian value-recovery bet.

Elevance Health (ELV) and Cigna Group (CI)

ELV (formerly Anthem) has more diversified Blue Cross Blue Shield commercial-insurance plus Carelon health-services revenue. CI has Express Scripts PBM plus commercial-insurance mix. Both faced less direct v28 impact than HUM. Active managers hold ELV and CI at slight overweights versus index, similar to UNH positioning pattern.

How to read managed-care 13F positioning

Three rules:

Rule 1: Read each company's Medicare Advantage exposure

Position changes through 2024-2025 reflect each company's specific Medicare Advantage revenue mix. Humana (high MA exposure) saw heaviest positioning unwinding; UnitedHealth (diversified) saw position reductions but not capitulation; ELV and CI saw modest position adjustments.

Rule 2: Watch value-discipline contrarian positioning

Dodge & Cox's 1.08% HUM concentration is the cleanest value-discipline contrarian signal in the sector. Other value-discipline managers (Fisher Asset Management, Wellington, GAMCO) have built or maintained meaningful positions in managed-care names through the stress cycle.

Rule 3: Cross-check with cybersecurity-and-regulatory disclosure

Managed-care insurers face elevated cybersecurity threats (Change Healthcare 2024 breach) plus ongoing CMS regulatory adjustment. Position changes through these stresses signal whether institutional views treat the overhang as transitory or structural.

What to track

1. 2026 medical-cost ratio trajectory. Each managed-care insurer reports quarterly MCR — the central operational metric for profitability through the v28 repricing cycle.
2. CMS Medicare Advantage benchmark-rate announcements. Annual CMS rate-update releases (typically in April) shape next-year plan economics.
3. Dodge & Cox Q2 2026 13F (due August 14, 2026). Watch whether the HUM position holds, expands, or trims. Track via the institutional signals feed.
4. Healthcare cybersecurity disclosures. Any new managed-care cyber incident would reshape the institutional risk premium.
