Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
Humana entered the Medicare Advantage market after pivoting from hospitals to managed care in the 1990s. The company was a mid-tier health insurer with the Chipps lawsuit exposing denial bonus schemes, but MA plans were relatively generous as the program competed for enrollment. Prior authorization practices and risk adjustment coding were less aggressive in the program's early years.
Humana grew to capture 16% of Medicare Advantage enrollment and acquired Concentra for $790 million to begin vertical integration. The MA industry matured with rising prior authorization utilization and risk adjustment coding becoming standard profit levers. Humana's marketing practices attracted CMS scrutiny, including the 2007 PFFS marketing suspension, and the 2015 CMS penalty was based on 2015 audit data reflecting practices established in this era.
After the DOJ blocked Aetna's $37 billion acquisition, Humana charted an independent course focused on Medicare Advantage dominance and vertical integration. The company acquired a 40% stake in Kindred at Home for $800 million and began building senior-focused primary care clinics. CMS levied a record $3.1 million penalty for systematic MA plan violations, and OIG audits found nearly $200 million in risk adjustment overpayments, revealing deepening patterns of regulatory noncompliance.
Humana completed its $5.7 billion acquisition of Kindred at Home and launched the CenterWell brand, unifying primary care, home health, and pharmacy under one vertically integrated platform. The company exited commercial employer insurance to concentrate entirely on government programs. A $1 billion value creation initiative drove layoffs of 1,000+ workers and closure of SeniorBridge facilities. The OIG's $197.7 million overpayment finding underscored risk adjustment coding concerns.
Humana's star ratings catastrophically dropped from 94% to 25% of members in 4-star plans, triggering a $3.5 billion revenue headwind and 23% stock crash. A class-action lawsuit alleged Humana used the nH Predict AI algorithm to systematically deny rehabilitation care. The Senate investigation documented a 16x higher post-acute care denial rate. Humana sued CMS twice over star ratings and lost both times, while settling the $90 million Part D fraud whistleblower case.
Humana exits plans in two states and 194 counties, potentially displacing 500,000 members while raising premiums 22%. The DOJ filed a kickback lawsuit alleging Humana paid illegal broker commissions and discriminated against disabled beneficiaries. OIG audits continue finding noncompliant diagnosis codes. CenterWell's vertical integration deepens with $20+ billion in annual revenue, while the company manages the financial fallout from the star ratings collapse under new CEO Jim Rechtin.
Alternatives
An integrated insurer-provider model with significantly lower claim denial rates and higher member satisfaction than Humana. Because Kaiser employs its own doctors, the prior authorization adversarial dynamic and ghost network problems are structurally absent. The catch: Kaiser is only available in 8 states and D.C., and you must use Kaiser's own network exclusively. If you live in a Kaiser service area and have Medicare Advantage or employer plan choice, it's the clearest structural alternative.
For Humana Medicare Advantage enrollees: switching back to traditional fee-for-service Medicare paired with a Medigap supplemental policy eliminates the prior authorization denials that Humana's Senate-investigated 16x post-acute denial rate represents. You can see any Medicare-accepting provider nationwide with no ghost networks. Moderate switch — requires comparing Medigap plan options and timing the move to an enrollment window. Generally costs more in premiums but avoids Humana's benefit cuts and plan exits forcing up to 500,000 members out.

Humana Spins Off Hospital Division as Galen Health Care
After growing into the nation's largest hospital operator with 77 hospitals, Humana spun off its hospital operations as Galen Health Care to focus exclusively on managed care health insurance. Galen was subsequently acquired by Columbia Hospital Corporation for $3.2 billion. The spinoff marked Humana's transformation from a hospital company into a pure-play health insurer.
Chipps Lawsuit Exposes Humana Denial Bonus Scheme
After six years of litigation, a Florida jury awarded the Chipps family $1.03 million in compensatory and $78.5 million in punitive damages against Humana for denying physical and occupational therapy to a child with cerebral palsy. The landmark case uncovered that Humana paid bonuses to physicians and nurses based on the number of medical claims they denied each month, revealing systemic incentives to restrict care.
Humana Enters Medicare Advantage Market
Humana began selling Medicare Advantage and Medicare Prescription Drug Plans, pivoting its business model toward government-funded senior healthcare programs. This strategic shift would eventually make government programs approximately 85% of Humana's revenue, creating deep dependence on Medicare payment structures and star rating bonuses.
CMS Suspends Humana's PFFS Marketing Over Violations
CMS required Humana and six other health plan sponsors to voluntarily suspend marketing of Private Fee-For-Service Medicare Advantage plans due to concerns about misleading marketing practices targeting seniors. Humana's marketing suspension lasted until the company demonstrated compliance with new broker certification requirements, beneficiary confirmation procedures, and disclaimer language standards.
Medicare Advantage Industry Accumulates $70 Billion in Improper Payments
An investigation by the Center for Public Integrity documented that Medicare Advantage plans accumulated nearly $70 billion in improper payments from 2008 through 2013, primarily from inflated diagnosis codes overstating how sick patients were. CMS estimated $14.1 billion in improper MA payments for 2013 alone. Humana, as a major MA insurer with growing enrollment, participated in industry-wide risk adjustment coding practices that generated excess government payments through unsupported diagnoses.
OIG Reports MA Plans Improperly Deny Prior Authorization for Covered Services
HHS OIG investigations during the late 2000s found that Medicare Advantage plans routinely denied prior authorization requests that met Medicare coverage rules. The reports documented that MA plans including Humana used prior authorization as a cost-control mechanism that delayed or denied beneficiaries' access to medically necessary services. These findings established the baseline pattern of prior authorization overuse that would intensify throughout the 2010s and 2020s.
Humana Acquires Concentra for $790 Million
Humana completed its acquisition of Concentra Inc. for approximately $790 million in cash, expanding into primary care practices and occupational health services. This represented Humana's first major step toward vertical integration into healthcare delivery, though Concentra focused on occupational health rather than senior care. Humana later sold Concentra in 2015 for $1.06 billion to refocus on senior-specific primary care.
Humana Approves New Share Buyback Replacing Existing $1 Billion Program
Humana's board approved a new share repurchase program replacing an existing $1 billion authorization that had $782 million remaining, set to expire December 31, 2016. The ongoing buyback programs continued alongside rising executive compensation and Medicare Advantage premium collection, reflecting standard public-insurer shareholder extraction patterns during a period of rapid MA enrollment growth.
Humana Part D Dual-Books Fraud Spans 2011-2017
A whistleblower lawsuit later revealed that from 2011 through 2017, Humana maintained two sets of actuarial books for its Medicare Part D Walmart Plan: accurate internal cost predictions used for business planning, and inflated projections submitted to CMS to secure higher government payments. The dual-bookkeeping scheme, exposed by former actuary Steven Scott in 2016, resulted in Humana overcharging the government by hundreds of millions of dollars over the period.
CMS Levies Record $3.1 Million Penalty Against Humana
CMS imposed a $3.1 million civil money penalty against Humana, the largest single penalty against the 129 organizations found in violation of Medicare Advantage and prescription drug plan requirements. The audit found that Humana routinely had unapproved prescription drug limits and imposed barriers for seniors to receive care. CMS Director Gerard Mulcahy noted systemic failures in complying with Parts C and D requirements.
Aetna Announces $37 Billion Acquisition of Humana
Aetna announced it would acquire Humana for approximately $37 billion in cash and stock, which would have created the nation's largest health insurer by Medicare Advantage enrollment. The merger would have combined two of the five largest U.S. health insurers, concentrating significant Medicare Advantage market power. The DOJ subsequently challenged the deal on antitrust grounds.
Humana Offers Early Retirement Buyouts Preceding 1,300 Layoffs
Humana offered voluntary early retirement buyouts to employees, a precursor to the company ultimately laying off approximately 1,300 workers. The workforce reductions reflected Humana's restructuring in the aftermath of the failed Aetna merger, as the company adjusted its cost structure for independent operation focused on Medicare Advantage growth. By 2019, Humana had trimmed its workforce by 27% over four years.
Federal Judge Blocks Aetna-Humana Merger on Antitrust Grounds
U.S. District Judge John D. Bates blocked Aetna's $37 billion acquisition of Humana, ruling it would substantially reduce competition for Medicare Advantage plans and individual exchange insurance. The court also found that Aetna had strategically withdrawn from insurance exchanges to pressure the DOJ into approving the merger. Aetna paid Humana a $1 billion breakup fee, and Humana remained independent.
Humana Acquires 40% Stake in Kindred at Home for $800 Million
Humana purchased a 40% ownership stake in Kindred at Home, the nation's largest home health and hospice provider, for $800 million alongside private equity firms TPG Capital and Welsh, Carson, Anderson & Stowe. This initial investment laid the groundwork for Humana's vertical integration into home health services, creating the infrastructure for self-referral dynamics between its insurance and provider operations.
OIG Finds 18% of MA Prior Authorization Denials Were Improper
An HHS OIG report found that Medicare Advantage organizations, including Humana, denied 18% of prior authorization requests that actually met Medicare coverage rules, and 13% of payment requests for services already provided. The report documented that MA plan denials delayed or denied beneficiaries' access to medically necessary services. The findings showed Humana participating in industry-wide patterns of prior authorization overuse to restrict access to covered care.
Humana Cuts 800+ Jobs in Workforce Optimization Despite Strong Financials
Humana announced plans to cut more than 800 employees, approximately 2% of its workforce, by end of 2019 in a 'workforce optimization' initiative costing $46 million. The layoffs came despite strong financial performance, with analysts praising the company's position. Humana had already trimmed its workforce by 27% over the previous four years, including a 2,700-person reduction approximately two years prior, reflecting a pattern of continuous restructuring.
MA Marketing Complaints Double as Aggressive Enrollment Tactics Escalate
CMS data revealed that Medicare beneficiary complaints about private-sector Medicare Advantage marketing more than doubled from 2020 to 2021. A subsequent Senate Finance Committee investigation found evidence that beneficiaries were inundated with aggressive marketing tactics and false and misleading information during enrollment periods. Humana's MA plans were among those investigated for marketing practices that prioritized enrollment volume over plan suitability for seniors.
OIG Audit Finds Humana Overcharged Medicare by Nearly $200 Million
An HHS Office of Inspector General audit found that Humana's Florida health plan improperly collected approximately $197.7 million in 2015 by overstating how sick some patients were through inaccurate diagnosis codes. The overpayment came from a plan that received $5.6 billion in Medicare payments for approximately 485,000 members. OIG recommended full repayment and improved compliance controls, though Humana contested the methodology.
Humana Completes $5.7 Billion Acquisition of Kindred at Home
Humana completed the acquisition of the remaining 60% of Kindred at Home for $5.7 billion in cash and debt, gaining full ownership of the nation's largest home health and hospice provider. The acquisition gave Humana direct control over home health delivery for its Medicare Advantage members, deepening vertical integration and creating self-referral pathways between Humana insurance plans and Humana-owned home health agencies.
Humana Launches CenterWell Brand Unifying Healthcare Services
Humana rebranded its healthcare services division under the CenterWell name, consolidating Kindred at Home into CenterWell Home Health and unifying primary care clinics and pharmacy operations. The CenterWell brand encompasses senior-focused primary care, the nation's largest home health operation, and pharmacy services, creating a single vertically integrated healthcare services platform under the Humana umbrella.
Senate Investigation Finds MA Plans Including Humana Used Aggressive Marketing Targeting Seniors
A Senate Finance Committee investigation found evidence that Medicare Advantage beneficiaries were inundated with aggressive marketing tactics and false and misleading information during enrollment periods. The investigation documented that brokers steered seniors to plans based on commission payments rather than plan suitability. CMS subsequently launched an inquiry into misleading marketing practices across major MA insurers including Humana, UnitedHealthcare, and WellCare.
Humana Launches $1 Billion Value Creation Cost-Cutting Initiative
Humana announced a $1 billion value creation initiative to fund investment in its Medicare Advantage business through cost-cutting measures including workforce reductions, real estate portfolio trimming, vendor spending cuts, and task automation. The initiative led to the closure of 23 SeniorBridge home care facilities and layoffs of over 1,000 workers in 2023, while the savings were directed toward MA plan competitiveness rather than member benefits.
Humana Exits Commercial Employer Insurance to Focus on Medicare
Humana announced it would exit the Employer Group Commercial Medical Products business, including all fully insured, self-funded, and Federal Employee Health Benefit plans, over 18-24 months. The decision concentrated Humana's business almost entirely on government-funded programs, with Medicare Advantage representing approximately 85% of revenue. This deepened Humana's dependence on Medicare payment structures and star rating bonuses.
SeniorBridge Closures Complete with 1,162 Workers Laid Off
Humana completed the closure of all 23 SeniorBridge home care facilities across two states, resulting in the layoff of at least 1,162 employees including 149 caregivers in Jupiter, Florida alone. The closures were part of Humana's $1 billion value creation initiative, which prioritized cost reduction in MA operations over maintaining the home care service line for vulnerable seniors.
CenterWell Plans to Route All Primary Care Patients to Owned Home Health
Humana announced plans to route nearly all CenterWell Primary Care patients needing home health services through its own CenterWell Home Health agencies, targeting a 25% increase in value-based home health admissions. This self-referral strategy exemplifies the closed-ecosystem approach where Humana captures revenue at both the insurance and provider stages, potentially limiting members' choice of independent home health providers.
Class Action Alleges Humana Used AI Algorithm to Deny Care
Medicare Advantage beneficiaries filed a class-action lawsuit alleging Humana used the nH Predict AI algorithm to prematurely cut off payment for rehabilitation care. The suit claimed the algorithm, developed by UnitedHealth subsidiary NaviHealth, generated highly inaccurate recovery predictions that were used to deny claims in favor of rigid algorithmic determinations over doctors' clinical recommendations. Humana sought dismissal on jurisdictional grounds.
Humana Settles Part D Fraud Whistleblower Case for $90 Million
Humana agreed to pay $90 million to settle a whistleblower lawsuit alleging the company submitted fraudulent bids to CMS for Medicare Part D prescription drug contracts from 2011 to 2017. Former Humana actuary Steven Scott alleged the company kept two sets of books, using different cost assumptions for government bids than for internal budgeting. The whistleblower received $26.1 million, representing 29% of the government's recovery.
Star Ratings Collapse: 94% to 25% in 4-Star Plans
CMS released 2025 star ratings showing Humana's enrollment in 4-star-or-above plans crashed from 94% to just 25%, the largest drop of any major MA insurer. One contract representing 45% of Humana's MA membership and 90% of employer group plans fell from 4.5 to 3.5 stars. Analysts estimated a $1-3.5 billion revenue headwind for 2026 from lost quality bonus payments, triggering a 23% stock price decline in a single day.
Senate Investigation Finds Humana Post-Acute Denial Rate 16x Overall
A Senate investigation documented that Humana's prior authorization denial rate for post-acute care services was more than 16 times higher than its overall denial rate, with long-term acute care hospital denial rates increasing 54% between 2020 and 2022. The report found that Humana had conducted training sessions that led to escalated denial rates for expensive post-acute services, indicating targeted algorithmic restriction of costly care categories.
Humana Sues CMS Over Star Ratings, Loses Lawsuit
Humana filed suit against HHS alleging the 2025 star ratings determination was arbitrary and capricious. A federal judge dismissed the case, ruling Humana had failed to exhaust administrative remedies. Humana subsequently filed an administrative appeal with CMS, which was also denied. The litigation strategy of suing the regulator rather than addressing underlying quality issues reflected Humana's confrontational regulatory posture.
Humana Lists Out-of-Network Providers as In-Network During Enrollment
The Minnesota Star Tribune reported that Humana listed Essentia Health, Avera Health, North Memorial Health, and Sanford Health as in-network for 2025 MA plans despite these health systems announcing they would be out-of-network. Minnesota Attorney General Keith Ellison sent a formal letter demanding Humana correct the misinformation and explain the extent of the inaccurate listings, marking one of the first state enforcement actions against Medicare Advantage ghost networks.
OIG Audit Finds Noncompliant Diagnosis Codes at Humana Louisiana
An HHS OIG audit of Humana Health Benefit of Louisiana found that most selected diagnosis codes submitted to CMS for risk adjustment did not comply with federal requirements, with 202 of 240 sampled enrollee-years containing unsupported diagnosis codes. The audit resulted in at least $13.1 million in identified overpayments for 2017-2018, with $6.8 million recommended for refund. The findings were part of a broader series of OIG audits targeting MA risk adjustment practices.
CenterWell Segment Hits $5.1 Billion Quarterly Revenue with 34.6% Profit Growth
Humana's CenterWell segment reported $5.1 billion in Q1 2025 revenue with operating income of $451 million, up 34.6% year-over-year. CenterWell Pharmacy expanded its partnership with Novo Nordisk to sell GLP-1 medications directly to consumers at $599-$699 per vial through telehealth and home delivery. The vertical integration model increasingly monetized member health needs across insurance, primary care, home health, and pharmacy channels simultaneously.
DOJ Sues Humana Over Medicare Advantage Broker Kickbacks
The Department of Justice filed a False Claims Act complaint alleging Humana, along with Aetna and Elevance, paid hundreds of millions of dollars in illegal kickbacks to brokers eHealth, GoHealth, and SelectQuote from 2016 through at least 2021 in exchange for steering Medicare beneficiaries into their plans. The DOJ further alleged Humana conspired with brokers to discriminate against disabled Medicare beneficiaries perceived as less profitable by threatening to withhold payments.
Humana Offers Early Retirement Buyouts to 30,000+ Employees
Humana offered voluntary early retirement buyouts to employees age 50 or older with at least three years of service, with social media reports indicating at least 30,000 employees received the offer out of a workforce of 64,000. The buyouts were part of a broader transformation agenda including expanded outsourcing of shared service functions and benefit adjustments. A similar offer in 2017 preceded layoffs of 1,300 workers, raising expectations of further workforce reductions.
Humana Exits Plans in Two States, Displaces Up to 500,000 Members
Humana announced it would drop plans in two states and 194 counties for 2026, reducing its footprint from 48 to 46 states and from 89% to 85% of U.S. counties, potentially displacing up to 500,000 members. Average MA premiums increased approximately 22% for 2026. The cuts followed the star ratings collapse and $3.5 billion revenue headwind, forcing benefit reductions and plan exits across the portfolio.
Humana Reports $3.5 Billion Star Ratings Revenue Headwind for 2026
Humana's Q4 2025 earnings report confirmed a $3.5 billion revenue headwind from lost star rating bonus payments, forcing conservative 2026 guidance. Shares plunged on the announcement. Only 20% of members remained in 4-star-or-above plans for 2026, down from 94% in 2024. CEO Jim Rechtin's first full year at the helm was defined by managing the financial fallout from the star ratings collapse.
