Marcus Holloway has been the operating partner for an ambulatory surgery center platform for two years. The platform owns fifteen ASCs across four states, primarily orthopedic and gastroenterology focused, with a smaller pain management footprint. Marcus can name, without consulting a list, the four surgeons across the platform whose departure would individually impair platform EBITDA by more than 8 percent. One of those four is showing the early signals he has learned to recognize: slightly fewer cases this month than last, slightly more equipment complaints from his cases, a slightly cooler interaction with the OR director during his last visit. Marcus does not yet know whether the signals add up to anything actionable, and the surgeon himself has said nothing to suggest he is unhappy. By the time the signals are unambiguous, Marcus has learned, the surgeon’s contract with the competing ASC twenty minutes away has often already been signed.
The ASC vertical has a dynamic that distinguishes it sharply from the rest of the clinical portfolio. Revenue depends on surgeons who are not employees but independent practitioners choosing where to bring cases. A surgeon unhappy with scheduling efficiency, equipment availability, or staff competence simply moves cases to a competitor. Surgeon relationship management is the ASC equivalent of the referring physician relationship in imaging, but the concentration risk is more extreme. A single high-volume surgeon may represent 20 to 30 percent of a center’s revenue. Two or three together may represent the majority. Surgeon loss is not a relationship issue. It is a platform-level revenue event.
The referral and relationship concierge described in BOI-01.16 carries its highest concentration risk in this setting. The scheduling concierge described in BOI-01.06 carries unique complexity around OR block time. The supply chain concierge described in BOI-01.08 handles implant management, which is operationally distinct from any other supply chain in healthcare. The credentialing concierge described in BOI-01.11 manages a multi-facility privileging matrix that grows quadratically as the platform adds centers.
The block time puzzle
Consider a four-OR ASC running a typical orthopedic and GI mix. Surgeon A is consistent. His cases finish 20 percent faster than the scheduled duration, leaving the OR idle and the staff waiting for the next case to start. Surgeon B is less consistent. His cases run 30 percent over scheduled duration, which cascades through the rest of his block and delays the surgeon scheduled after him. Surgeon C books her block aggressively but uses it at 60 percent capacity, leaving slots open she will not release for other surgeons because she may need them for late-add cases that occasionally materialize.
Each pattern, considered alone, has a tempting solution. Reduce Surgeon A’s block. Extend Surgeon B’s scheduled durations. Take back Surgeon C’s unused capacity. Each solution, applied, risks the surgeon’s departure. Surgeon A interprets the block reduction as the ASC valuing his volume less. Surgeon B interprets the duration extension as the ASC complaining about his pace. Surgeon C interprets the capacity recovery as the ASC prioritizing other surgeons over her.
The scheduling concierge takes a different approach. It learns the actual durations of each surgeon’s cases over a representative period, by case type, by anesthesia type, by the specific OR team configuration. It builds a predictive duration model per surgeon per case type. It then proposes block allocation adjustments that respect the surgeons’ preferences while improving the platform’s effective capacity. Surgeon A keeps his block size but the cases scheduled within it match his actual pace, leaving the OR genuinely available for waitlist cases at the predicted end times. Surgeon B’s scheduled durations are extended to match his pace, with the implication surfaced gently: the schedule now reflects how his cases actually run, which removes the time pressure on his block and reduces cascading delays. Surgeon C’s unused capacity is offered to her first for late-add cases; if she declines, it releases to a waitlist after a predefined window.
The concierge does not impose any of these changes. It surfaces the proposals to the OR director, who reviews them with each surgeon in the relationships she has built over years. The architecture exists to make the conversation easier, not to replace it.
Surgeon relationship management
A surgeon’s relationship with an ASC is encoded in operational signals that the ASC’s existing systems capture but rarely aggregate. Case volume trending against the surgeon’s historical baseline. Block usage rate over rolling windows. Equipment and supply complaints logged by the circulating staff. Scheduling friction signals: requests for specific OR teams that have to be declined, requests for case sequencing that conflict with anesthesia availability, last-minute changes initiated by the surgeon’s office that the scheduling staff find annoying enough to mention in shift notes. Interactions between the surgeon and the ASC staff that produce the kind of feedback the OR director hears in passing rather than in formal channels.
The referral and relationship concierge running on the ASC platform aggregates these signals into a relationship score per surgeon. The score is not a ranking. It is a state estimate, refined over time, of how this surgeon’s relationship with this ASC is trending. The score weights financial contribution against relationship risk: a surgeon contributing 25 percent of revenue with a declining relationship trajectory ranks higher in the platform’s attention queue than a surgeon contributing 4 percent with the same trajectory.
The platform-level dashboard Marcus reviews each Monday surfaces three views: the most financially valuable surgeons across the portfolio, the surgeons whose relationship signals indicate elevated risk, and the operational factors most strongly correlated with the risk signals. The third view is what makes the dashboard useful. It tells him not just which surgeons are at risk but what is producing the risk, which is the actionable information he needs to direct attention. The surgeon showing equipment-complaint signals concentrated at one specific center needs an equipment review at that center. The surgeon showing scheduling-friction signals across multiple centers needs a coordinated scheduling conversation rather than per-center patching.
Implant and supply chain
ASC supply chains are dominated by implants, which are operationally distinct from every other clinical supply category. Implants are typically held on consignment: the vendor stores them at the ASC, the ASC uses them in cases, the ASC bills the vendor monthly for what was used. The consignment relationship requires precise tracking of which implants were used in which case for which surgeon, billed against which payer, at which contracted price.
Preference card management compounds the complexity. Each surgeon has preferences for specific implant brands, specific instrument sets, specific suture types, and specific draping configurations. The preferences are not standardizable across surgeons without risking the surgeon relationship. They are, however, operationally expensive when each surgeon’s preferences require dedicated inventory and dedicated setup time. The supply chain concierge maintains the preference cards, tracks the inventory implications, and surfaces the pricing variance across vendors for implants that multiple surgeons accept.
Vendor contract analysis is the portfolio-level layer. Implant pricing varies significantly across vendors and across negotiated contracts. A knee replacement implant from Vendor X may be 18 percent more expensive than the operationally equivalent implant from Vendor Y, with the difference reflecting historical negotiation rather than current vendor pricing pressure. The supply chain concierge at the portfolio level identifies the pricing variance and the surgeon-acceptance constraints that determine which variances are addressable. Some surgeons will accept any quality-equivalent implant. Others have strong preferences that cannot be changed without risking case volume. The concierge surfaces the addressable variance and leaves the surgeon-relationship judgment to the operating partner and the OR director.
Credentialing and privileging
A surgeon’s privileges to operate at an ASC are facility-specific. A surgeon credentialed at Center A cannot bring a case to Center B in the same portfolio unless she is also credentialed at Center B. The privileges have to be active. The malpractice insurance certificate has to be current at each facility. The board certifications have to be verified. The state license has to be in good standing.
For a portfolio with fifteen ASCs and eighty active surgeons, the privileging matrix has 1,200 cells. Each cell carries its own status, its own expiration timing, and its own documentation requirements. Some surgeons are credentialed at all fifteen centers. Most are credentialed at three to six. A handful are credentialed at one. The credentialing concierge maintains the matrix in real time, surfaces upcoming expirations sixty days in advance, and flags the credentialing applications that are stalled in payer or accreditation body processing.
When a surgeon requests privileges at an additional center, the concierge initiates the application with the documentation already on file, requesting only the incremental documentation the new center requires. The time from request to active privileges, typically eight to fourteen weeks in manual processes, falls to four to seven weeks when the documentation handling is automated against the maintained matrix. The reduction matters operationally because the surgeon who requests privileges at a second center is often planning to redirect cases. The faster the privileging completes, the sooner the platform captures the case volume.
Quality and compliance
CMS ASC Quality Reporting tracks five categories the operating partner reviews quarterly: infection rates, patient fall incidents, wrong site surgery events, hospital transfer rates, and burn events. The categories are mandatory reportable, and the data feeds into the payment determination for the following year. State licensure layers additional requirements that vary significantly: California, Texas, and Florida each have distinct ASC regulatory frameworks. Infection control reporting connects to local public health authorities in some states. Equipment inspection schedules apply to lasers, electrosurgical units, anesthesia machines, and the autoclaves.
The compliance concierge tracks the reporting categories at the center level and aggregates to portfolio level for benchmarking. The benchmarking is the operationally interesting layer. A center with an infection rate that is statistically higher than the portfolio median is identifiable within a quarter, well before the rate becomes a regulatory concern. The early identification permits operational intervention before the rate becomes a reporting event. The portfolio average is not a target. It is a baseline against which outliers become visible.
Consumer connection
The consumer connection in the ASC vertical is real but narrower than in other clinical settings. Aging adults undergo procedures at ASCs primarily in three categories: cataract surgery, joint replacement, and screening or diagnostic endoscopy. For each, the health concierge documented in BMT-01.02 coordinates surrounding the procedure rather than during it.
For cataract surgery, the health concierge coordinates the pre-op clearance, the transportation arrangement on the day of the procedure given that the patient cannot drive afterward, and the post-op follow-up scheduling. The ASC’s operational agents handle the procedure itself, the implant tracking, and the billing. The membrane permits the exchange of clinical context required for scheduling and pre-op preparation without exposing the patient’s full medical record to the ASC’s systems.
For joint replacement, the coordination extends further. The pre-op optimization typically involves nutrition, mobility preparation, and home environment modifications that the consumer’s nutrition concierge and home environment concierge handle separately. The post-op recovery extends weeks to months and involves physical therapy coordination, pain management monitoring, and the home care arrangements that may be required transiently. The ASC’s operational layer focuses on the procedure window. The consumer concierges handle everything before and after, with the ASC’s discharge documentation flowing back through the membrane to inform the recovery coordination.
For endoscopy, the coordination is shorter but operationally distinct. The pre-op preparation involves the bowel preparation protocol the patient must complete the day before, which intersects with her medication schedule, her nutrition concierge, and her overall daily routine in ways that the consumer side handles better than the ASC can. The ASC schedules the procedure. The consumer concierge handles the preparation, and the result returns through the membrane to her health concierge for interpretation.
The consumer connection here is narrower in scope than at the imaging center, but the architectural pattern is the same. The operational platform handles its operational work. The consumer concierges handle the consumer’s experience. The membrane permits the exchange that lets each side do its job better, without violating the boundary that makes each side trustworthy.
