EP505: The Death of the “What Is Value” Guessing Game for Clinical and Plan Decision-Makers Ready to Move On, With Ahilan Sivaganesan, MD
Release Date: 04/02/2026
Relentless Health Value
Stacey Richter interviews neurosurgeon Dr. Ahilan Sivaganesan (Dr. Siva) about replacing vague healthcare “value” claims with quantified outcomes and unit-level costs, introducing his Operative Value Index (OVI). They discuss how hospitals often lack true internal episode costs and how common quality metrics miss patient-reported outcomes and appropriateness across the full care journey. Using time-driven activity-based costing (TDABC) and condition- or procedure-specific patient-reported outcomes, OVI creates a common mathematical language to compare surgeons, practices, or health...

Why Advanced Primary Care Doesn’t Scale: Conflicting Incentives, Complacency, and a 3-Step Roadmap Stacey Richter interviews Ryan Jacobs (SVP Strategy and Partnerships, Marathon Health) on why evidence-backed advanced primary care (APC)—focused on managing risk, improving outcomes, and lowering costs—still isn’t widespread. They argue APC struggles to scale due to two root barriers: conflicting fiduciary duties (health systems and payers driven by volume, “heads in beds,” and market-power growth, while APC keeps patients out of hospitals) and a “black box of complacency,”...

In this Inbetweenisode, Stacey shares listener feedback and reflects on making better decisions in employer-sponsored healthcare, spotlighting LinkedIn posts by Ken Wosczyna and Michelle Bernabe. Ken argues Relentless Health Value moves from theory to practical transformation by sharpening judgment, which Stacey ties to how millions of workplace decisions shape the healthcare system and how actuaries and executives can align choices with values. Stacey emphasizes that good decisions require both transparency and understanding, previewing an upcoming episode with Jerry DiMaso about...

Episode 503 of Relentless Health Value features Stacey Richter with Adam Stavisky, Dr. Leo Spector (OrthoCarolina), and Ryan Wells (Health Here) discussing how self-insured employers and specialists rarely connect directly due to intermediaries and fee-for-service “rails.” They outline three common pitfalls when bridging this gap: defining and measuring quality and appropriateness (limits of claims data and missing patient-reported outcomes), achieving scale across geographies and specialties, and ensuring benefit design and incentives so members actually use direct-contracting...

Episode 502 features Stacey’s conversation with Brian Machut (Alliant Health) on how widespread Medicare fee-for-service fraud is inflating costs and undermining ACO shared savings in MSSP and ACO REACH. ACOs uncovered major urinary catheter fraud in 2023 tied to codes A4352/A4353, totaling about $3.5B, with some beneficiaries billed for items never received (including a case shared by Dr. Tara Lagu). CMS created a “SAHS” (significant, anomalous, highly suspect) process to remove certain suspect costs, but benchmark effects can unevenly impact ACOs; catheter fraud is still...

Episode 501 of Relentless Health Value features Stacey Richter interviewing Ivana Krajcinovic, outgoing Vice President of Healthcare Delivery at Unite Here Health, about extreme and persistent price variation for medical infusions as evidence of a “no market” in healthcare. They cite examples where the same chemotherapy drug (Oxaliplatin), long off patent, cost Medicare about $35 (or $185 for a series), an independent practice about $135, but a hospital in Chicago charged $13,560 and a hospital in Monterey billed $90,000 for a series—markups described as up to nearly 500x and far beyond...

The Non-Market Reality of Healthcare Carrier Marketplaces with Dr. Jacob Asher. In this episode of Relentlessly Seeking Value, host Stacey Richter introduces the 'No Market' series focused on the healthcare sector's lack of competitive market dynamics, which affects cost and quality. The episode features a conversation with Dr. Jacob Asher, who has extensive experience as a Chief Medical Officer at major healthcare plans. They discuss the stagnant nature of commercial carrier marketplaces, particularly in California, and the various factors contributing to this stasis, including employer...

In the milestone Episode 500 of the 'Relentless Health Value' podcast, Stacey Richter reflects on the significant influence and community formed around the platform. Initiated by a conversation with Cora Opsahl, the episode transforms into a heartfelt ode to the listeners — healthcare entrepreneurs, executives, and change-makers, whom Stacey refers to as 'the tribe.' Featured contributions from several listeners highlight themes such as moving from theory to practical transformation, the power of collective momentum, and 'unplugging from the Matrix' of opaque healthcare practices. ...

In this episode of Relentless Health Value, host Stacey Richter talks with Dr. Jay Kimmel, an orthopedic surgeon and co-founder of Upswing Health, about the significant costs associated with musculoskeletal (MSK) injuries and conditions for self-insured employers and other plan sponsors. They explore how a large portion of MSK-related expenses are for low-acuity injuries that often heal on their own without the need for emergency room visits or unnecessary treatments. Dr. Kimmel discusses the importance of addressing the 'white space'—the critical initial moments when a patient decides...

In Episode 498, host Stacey Richter converses with Mark Noel of ClaimInsight about the critical aspects of payment integrity within self-insured employers and plan sponsors, focusing on the arms race with revenue cycle management (RCM). The discussion reveals three main insights: the substantial impact of small claim errors, the inherent flaws and conflicts within prepayment analysis by TPAs, and the problematic financial incentives influencing claim processing. Noel emphasizes the importance of prepayment integrity for both plan savings and protecting members, underscoring the need for...

They discuss how hospitals often lack true internal episode costs and how common quality metrics miss patient-reported outcomes and appropriateness across the full care journey.
Using time-driven activity-based costing (TDABC) and condition- or procedure-specific patient-reported outcomes, OVI creates a common mathematical language to compare surgeons, practices, or health systems, risk-adjust for confounders, and support steering/tiering and direct contracting for self-funded employers.
Siva describes transparency via bubble charts that spur clinician behavior change without new incentives and argues this infrastructure is essential as bundled payments and risk-based arrangements expand, framing a “Yahoo vs Google” shift from fee-for-service volume to measurable value.
