Case III
Michael Kissling
Allentown, Pennsylvania · UnitedHealthcare Medicare Advantage
The Story
Michael Kissling was 15 when his doctors first identified an anatomical defect in his vasculature after a blood clot, May-Thurner syndrome — A defect insurance required it be proven again on imaging at 27 before considering a stent. — a vascular condition causing dangerous blood flow issues — and recommended an iliac vein stenting procedure with an 85–90% five-year patency rate. UnitedHealthcare denied it after extracting the out-of-pocket maximum for the imaging that proved its necessity.
Over the next several years, UHC also denied Apligraf — an FDA-approved wound care treatment cleared in 1998 and 2000 — for 17 months while non-healing wounds progressed. When Apligraf was finally approved, it closed the wounds in two weeks. It had taken 17 months and bone demineralization to get there.
On February 1, 2023, Kissling's leg was amputated above the knee. Pathology from the surgery described bone that had demineralized to a consistency "cuttable with a scalpel" — severe osteomyelitis caused by the prolonged wound care delays. His treating physician confirmed the amputation would not have been elective had the prior pathology been known; Kissling was "one bad step from compound fracture and death by bleeding out" due to his anticoagulant therapy.
The Prosthetic Denial — Prior Knowledge Omission Documented
Six weeks after the amputation, UHC approved a learner prosthetic — officially acknowledging Kissling's K3 functional mobility status (AMPnoPRO score: 35). This classification became mandatory knowledge in UHC's possession. Six months later, UHC denied the transition to a permanent tertiary prosthetic, claiming Kissling did not demonstrate sufficient functional ability to qualify.
UHC approves learner prosthetic — officially establishing K3 functional mobility status. This is mandatory knowledge in UHC's possession.
Six days after K3 establishment, UHC changes the beneficiary's plan — making all existing physicians and physical therapists out-of-network. Care continuity disrupted.
UHC denies permanent prosthetic — claiming insufficient functional ability — while possessing the K3 approval and an updated K4 physical therapy evaluation (AMPnoPRO: 44/47). UHC's reviewing physician explicitly refuses to acknowledge the K4 PT data because it was not written in his specific office note.
UHC final denial letter, signed by Senior Appeals Representative Christopher Toland, states: "Medicare Guidance says that the requested computerized knee advanced feet exceed your needs" — issued with documented prior knowledge that the patient was K3–K4, in direct violation of Medicare Policy Article A52496.
Maximus Federal Services (Independent Review Entity) immediately overturns UHC's denial. Finding: medically necessary. This overturn is equivalent to summary judgment — UHC's position was indefensible.
Medicare lowers the microprocessor knee standard from K3 to K2 — meaning Kissling would have qualified under even the future relaxed standard. UHC's denial had no medical or regulatory basis at any point in time.
The Smoking Gun — Dr. Stockhausen's Written Documentation
The attending physician, Dr. Sean T. Stockhausen, documented in writing that during the peer-to-peer review, the UHC reviewing physician:
- Confirmed he remembered arguing that the patient was K4
- Stated he could not use the objective PT data — including walking speed and AMPnoPRO score — because it was not written directly in his own office note
- Subsequently amended his own office note specifically to include the AMPnoPRO score
This is the Wrongful Denial Echo Chamber documented by the treating physician in writing: standardized, Medicare-approved assessment scores excluded on a procedural pretext manufactured by the corporate reviewer. Under Medicare LCD L33787 and Policy Article A52496, only one of three qualifying conditions was required for prosthetic replacement. Kissling met all three. UHC's reviewer knew this and denied anyway.
The Park
While using the inadequate learner prosthetic — the one UHC denied replacing — Kissling took his autistic daughter to a park. She became distressed and bolted toward the parking lot. He tried to run after her. The learner prosthetic failed. He nearly fell. He had to remove the prosthetic entirely. He could not reach her in time.
Another parent intervened and stopped her before she reached traffic.
Kissling has not taken his daughter outside alone since that day. UnitedHealthcare's denial removed his fundamental capacity to protect his child in an emergency. He has documented this in federal submissions. This is one of the damages in his case.
The Taxpayer Cost
The Wrongful Denial Echo Chamber does not save money. It transfers costs from the insurer onto taxpayers and onto the patient's body:
- A denied $55,000 stenting surgery triggered cascading wound failures over years
- 17 months of Apligraf delays allowed wounds to progress to bone-level infection
- The resulting amputation, revision surgeries, wound care, HBO therapy, prosthetics, and ongoing treatment costs: over $1.1 million in taxpayer-funded medical costs — and climbing
- Two university withdrawals: Kutztown University (3.92 GPA, Public Administration / paralegal) and Full Sail University (4.0 GPA, Course Director Award in Programming)
The $55,000 denial became $1.1 million in taxpayer costs. The insurer paid nothing. The patient paid with his limb. The public paid with their taxes.
What This Case Is Doing
In March 2026, Kissling submitted a formal briefing to the Senate Permanent Subcommittee on Investigations detailing the Prior Knowledge Omission mechanism as a documented, prosecutable fraud pattern — with a timestamped paper trail, physician corroboration, and an IRE-validated overturn as the evidentiary foundation.
The Clinical Integrity & Patient Safety Amendment — proposed as an addition to S.3829 — was drafted directly from this case. The Amendment's § 1 (Prohibition of Prior Knowledge Omission) names exactly what happened here. The § 5 Malpractice Trigger would have made the reviewing physician's refusal to acknowledge the K4 PT data a reportable act to the State Medical Board the moment Maximus overturned the denial.

Delay, Defend, Depose
How one man's decade-long fight with UnitedHealthcare reveals a system engineered to say no.
Shadowbanned Magazine's investigative feature traces the full arc of this case — from the first clot at 15, through the years of denied vascular care, to the amputation at 29 and the fight for a prosthetic that should never have required a fight. The piece documents the park incident with Lily, the whistleblower submission to the Senate PSI, the "Denial on Trial" reform framework, and the calculus behind why most patients never appeal. It is the most comprehensive single-publication account of this case in print.

The Weight of Knowing
"Someone has to watch the papers fly in a tornado."
— Michael Kissling
"Shouldn't someone smarter and better trained than me be doing this already — for every patient?"
— Michael Kissling
The coordination failure documented in this case isn't just about what insurers deny. It's about what the system requires patients and families to become — informal care coordinators, medical researchers, legal advocates — in the gaps between specialists, departments, and appeal deadlines. That role shouldn't fall to whoever loves the patient enough and happens to have stumbled into enough knowledge to fill it. It should be built into the system. It isn't.
