Referral Specialists Are Not State Actors Absent State Control: Seventh Circuit Reaffirms Limits of § 1983 Liability for Private Prisoner Care

1. Introduction

In Denon Taylor v. Samuel Byrd (7th Cir. June 24, 2026), Indiana prisoner Denon Taylor brought an Eighth Amendment medical-care suit under 42 U.S.C. § 1983 against (1) Dr. Samuel Byrd, the prison physician who managed Taylor’s ongoing care at Wabash Valley Correctional Facility, and (2) Dr. Kurt Madsen, a private orthopedic surgeon who treated Taylor through referral and performed three knee surgeries.

Taylor alleged the defendants were deliberately indifferent to his serious medical needs arising from chronic knee pain and limited mobility following a total knee replacement and subsequent procedures. The district court entered summary judgment for both defendants, concluding (among other things) that Dr. Madsen was not a state actor and that neither doctor’s conduct met the demanding “deliberate indifference” standard. The Seventh Circuit affirmed in a nonprecedential disposition.

The appeal presented two recurring issues in prison medical litigation: (a) when a private medical specialist treating a prisoner can be treated as a state actor for § 1983 purposes, and (b) when persistent conservative treatment and delays in obtaining second opinions cross the line from medical judgment into deliberate indifference.

2. Summary of the Opinion

The Seventh Circuit affirmed summary judgment for both defendants.

  • As to Dr. Madsen: No reasonable jury could find he acted “under color of state law.” His relationship with the prison system was “incidental and transitory,” he was not controlled or influenced by the state, he did not contract with the state, fewer than 2% of his patients were prisoners or detainees, and he did not manage Taylor’s longitudinal care. Even assuming state action, no reasonable jury could find deliberate indifference because Dr. Madsen responded to Taylor’s complaints with examinations, therapy recommendations, and additional surgery; at most Taylor alleged negligence.
  • As to Dr. Byrd: Even focusing on the post–March 2018 period (after the third surgery), no reasonable jury could find deliberate indifference. Dr. Byrd adjusted pain medications, ordered therapy, provided a brace, relied on specialist and therapist assessments, and ultimately sought another opinion when conservative measures ceased to help—leading to a successful revision surgery in 2022.

3. Analysis

3.1 Precedents Cited

Sanders v. Moss, 153 F.4th 557 (7th Cir. 2025)

The court began by reiterating the summary judgment posture: facts are recounted in the light most favorable to the nonmovant. This framing mattered because—even with favorable inferences—the evidentiary record did not permit a reasonable jury to find state action by Dr. Madsen or deliberate indifference by either doctor.

Rodriguez v. Plymouth Ambulance Serv., 577 F.3d 816 (7th Cir. 2009)

Rodriguez supplied the controlling analytic framework for determining whether a private medical provider acts under color of state law when treating a prisoner. The opinion emphasized three core points drawn from Rodriguez:

  • The inquiry is fact-intensive and uses a “functional analysis” focused on whether the conduct is “fairly attributable to the state.”
  • Key considerations include the extent to which the provider is “controlled or influenced by the state” and whether the provider has a sufficiently direct, ongoing relationship with the prisoner.
  • A provider with “only an incidental and transitory relationship with the state's penal system” is generally not a state actor.

The court used these Rodriguez factors to reject Taylor’s effort to transform a referral-based specialist into the functional equivalent of the state’s prison medical system.

Shields v. Ill. Dep't of Corr., 746 F.3d 782 (7th Cir. 2014)

Shields reinforced the distinction between a specialist who accepts a referral and a provider who assumes responsibility for the inmate’s overall medical care. The court cited Shields for the proposition that “accepting a referral as a specialist does not confer on a provider the responsibility of managing the patient's continued care.” That principle was pivotal: Dr. Madsen’s role was episodic (surgery and standard follow-ups), while Dr. Byrd managed the broader treatment plan, medications, and decisions about additional outside consultation.

Farmer v. Brennan, 511 U.S. 825 (1994)

Farmer supplied the constitutional mens rea requirement for Eighth Amendment medical claims: deliberate indifference requires evidence that the defendant knew of and disregarded an objectively serious medical condition.

McDaniel v. Syed, 115 F.4th 805 (7th Cir. 2024)

McDaniel was used to underscore the demanding nature of the deliberate indifference standard and to draw a firm line between constitutional tort and malpractice: “[n]egligence or even objective recklessness” is insufficient. This point disposed of Taylor’s theory insofar as it characterized Dr. Madsen’s unsuccessful surgeries as incompetent or mistaken rather than consciously indifferent.

Pyles v. Fahim, 771 F.3d 403 (7th Cir. 2014) and Sain v. Wood, 512 F.3d 886 (7th Cir. 2008)

These cases supplied the Seventh Circuit’s deference framework for prison medical decision-making when some treatment is provided. Courts defer to medical judgment unless “no minimally competent professional would have so responded under [the] circumstances.” The panel applied this to Dr. Byrd’s prolonged use of conservative measures—medications, therapy, brace, and monitoring—given the specialist’s opinion that no further surgical options remained and the therapist’s view that improvement had occurred.

Rodgers v. Rankin, 99 F.4th 415 (7th Cir. 2024)

Rodgers supported the proposition that a treating prison doctor may reasonably rely on the assessments of other professionals (specialists and therapists) when selecting and continuing a treatment plan. The court used Rodgers to justify Dr. Byrd’s reliance on Dr. Madsen’s conclusion that further surgery would not help and on therapy notes indicating improvement.

3.2 Legal Reasoning

A. The “Under Color of State Law” Requirement and Private Specialists

To sue under § 1983, a plaintiff must show the defendant acted “under color of” state law. The court treated this not as a formal label (private vs. public) but as a functional question: was the doctor’s conduct fairly attributable to the state?

Applying Rodriguez’s functional analysis, the court highlighted facts cutting against attribution:

  • No contract or employment relationship between Dr. Madsen and the state.
  • Limited prisoner caseload (fewer than 2% prisoners or detainees), undermining the notion that he functioned as the prison’s orthopedist.
  • No evidence of state control or influence over clinical decisions—no directives altering “the manner and the mode of care.”
  • Care structure: Dr. Byrd managed ongoing care; Dr. Madsen provided discrete specialist services (surgeries and routine post-op follow-ups).

Taylor argued that (1) voluntary acceptance of the referral and insurer payment, (2) an 11-visit/3-surgery relationship, and (3) treatment in a hospital unit dedicated to prisoners (guards, secured doors, restraints) established state action. The court rejected each:

  • Referral and payment do not equate to assuming the state’s constitutional duty to provide comprehensive prison medical care (per Shields).
  • Volume of encounters is not dispositive; the key is whether the provider’s work is controlled or influenced by the state (per Rodriguez).
  • Security conditions may be relevant, but only insofar as they influence medical decision-making; Taylor offered no evidence they did.

The result: even on Taylor’s version of events, a jury could not reasonably find state action, so § 1983 liability could not attach to Dr. Madsen.

B. Deliberate Indifference: Response vs. Disregard

The court also addressed the merits and reinforced a common theme in Eighth Amendment medical cases: persistent symptoms do not automatically imply deliberate indifference when clinicians are actively treating, reassessing, and making judgment calls.

1) Dr. Madsen

Even assuming arguendo that Dr. Madsen was a state actor, the record showed he did not disregard Taylor’s needs. He recommended physical therapy after the first surgery, reevaluated Taylor when pain and limited extension persisted, and proceeded to further surgical interventions when conservative measures were not successful. That the outcome was poor did not transform his care into deliberate indifference. Under Farmer and McDaniel, Taylor needed evidence of knowing disregard, not merely an inference of substandard performance.

2) Dr. Byrd

Taylor’s core complaint was delay: after the March 2018 third surgery, Dr. Byrd continued conservative management for years rather than promptly obtaining a different orthopedic opinion—only later discovering an alleged prosthesis-sizing issue and eventually securing revision surgery in 2022.

The court treated Dr. Byrd’s conduct as a sequence of reasoned medical steps: prescribing and changing pain medications, ordering therapy, providing a brace, obtaining imaging, consulting a regional medical director, and relying on (a) Dr. Madsen’s view that no further surgery would help and (b) physical therapy’s assessment that improvement had occurred. Under Pyles v. Fahim and Sain v. Wood, these actions did not approximate the “no minimally competent professional” threshold. When the conservative course proved inadequate, Dr. Byrd sought another opinion and the patient ultimately received corrective surgery.

3.3 Impact

A. Clarifying § 1983 Exposure for Private Referral Specialists

The decision reinforces (and operationalizes) the Seventh Circuit’s Rodriguez/Shields line: a private specialist who treats prisoners by referral—without a state contract, without state direction over clinical decisions, and without assuming longitudinal care—will typically be outside § 1983’s reach. The opinion discourages attempts to convert “accepted referral + repeated visits” into state action absent evidence of control, delegation, or integration into the prison’s medical system.

B. Reinforcing the High Bar for Deliberate Indifference Where Care Is Ongoing

For Eighth Amendment claims, the opinion underscores that long periods of conservative treatment, even if ultimately unsuccessful, do not equate to deliberate indifference when the clinician is actively adjusting medications, ordering therapy, seeking consultative input, and explaining risk tradeoffs. Plaintiffs will need evidence showing not just a better alternative in hindsight, but an unreasonable response so extreme that it falls outside minimally competent professional judgment.

C. Litigation Strategy Implications

Practically, the opinion signals that plaintiffs challenging delayed second opinions should focus on concrete evidence that treating providers:

  • ignored specialist recommendations or red flags,
  • failed to investigate worsening symptoms without explanation,
  • persisted in a known-ineffective approach with no clinical rationale, or
  • were constrained by non-medical directives affecting medical judgment.

On the defense side, contemporaneous documentation of clinical reasoning, reliance on consults, and stepwise treatment modifications remains central to summary judgment.

4. Complex Concepts Simplified

  • “Under color of state law” / “state actor”: A private person can be sued under § 1983 only if their conduct is effectively the state’s conduct. Courts look to function and control—whether the state directed, influenced, or delegated its constitutional duties to the private actor—not merely whether the person interacted with prisoners.
  • Functional analysis / “fairly attributable to the state”: A practical test from Rodriguez asking whether, in context, it is normatively fair to treat the private provider’s conduct as state action. Control, influence, and the provider’s role in the overall care structure are central.
  • “Incidental and transitory relationship”: A limited, episodic engagement with the prison system—such as discrete specialist treatment—typically insufficient to create § 1983 liability.
  • Deliberate indifference: More than malpractice. The plaintiff must show the defendant actually knew of a serious medical risk and consciously disregarded it (Farmer), and that the response was so inadequate it fell below minimally competent professional judgment (Pyles; Sain).
  • Summary judgment: A pretrial ruling that ends the case if no reasonable jury could find for the plaintiff on the evidence in the record (with inferences drawn in the plaintiff’s favor, per Sanders).

5. Conclusion

The Seventh Circuit’s decision affirms two stabilizing principles in prison medical § 1983 litigation. First, a private orthopedic surgeon who provides referral-based care—without a contract with the state, without evidence of state control over treatment decisions, and without responsibility for ongoing care—will not ordinarily be a state actor under Rodriguez v. Plymouth Ambulance Serv. and Shields v. Ill. Dep't of Corr. Second, where prison physicians provide ongoing treatment, adjust therapies, rely on specialist and therapist input, and articulate risk-based reasons for conservative management, the Eighth Amendment’s deliberate indifference standard (Farmer v. Brennan; Pyles v. Fahim) is not satisfied simply because the patient suffers for years or because later surgery proves beneficial.
