RubiconMD is a web- and EHR-integrated electronic consultation (eConsult) platform that connects primary care providers (PCPs) with board-certified specialists for asynchronous clinical guidance. By enabling primary care clinicians to transmit structured clinical questions, diagnostic images, and laboratory panels to specialists across more than 140 medical and surgical subspecialties, RubiconMD reduces avoidable face-to-face specialist referrals and supports value-based care delivery.
What Is RubiconMD?
Founded in 2013 and acquired by value-based primary care provider Oak Street Health in October 2021 (subsequently part of CVS Health), RubiconMD (https://www.rubiconmd.com/) operates a clinician-to-clinician asynchronous specialty consultation network. Unlike synchronous direct-to-patient telemedicine platforms (such as Amwell or Doxy.me), an eConsult platform mediates peer-to-peer communication between the treating primary care clinician and a reviewing specialist without requiring the patient to attend a separate appointment.
Core architectural components of the RubiconMD eConsult model include:
- Multi-Specialty Clinical Network: Access to vetted, board-certified specialists spanning adult and pediatric subspecialties—including cardiology, nephrology, hematology, endocrinology, dermatology, rheumatology, and neurology.
- Rapid Asynchronous Turnaround: Specialists review submitted clinical data and return a structured written care plan—typically averaging under 3 to 4 business hours and within a 1-business-day service-level agreement (SLA).
- Primary Care Scope Expansion: equips PCPs in federally qualified health centers (FQHCs), rural clinics, correctional health systems, and Medicare Advantage value-based clinics to manage complex conditions locally while escalating high-acuity cases to targeted in-person visits.
How Is RubiconMD Used in Clinical Research and Healthcare?
In clinical healthcare delivery and health services implementation research, RubiconMD is deployed to solve specialty access bottlenecks, standardize diagnostic workups prior to referral, and evaluate cost-of-care reductions in risk-bearing populations.
1. Asynchronous Clinical eConsult Workflow
- Case Formulation in the EHR: When a primary care clinician encounters a diagnostic ambiguity or medication management question (for example, interpreting an indeterminate protein electrophoresis panel or titrating heart failure guideline-directed medical therapy), the clinician launches RubiconMD directly from the EHR integration interface.
- Structured Data Attachment: The platform automatically pulls patient demographics, active medication lists, problem lists, and recent lab results via HL7 v2 or HL7 FHIR APIs, while prompting the PCP for specialty-specific clinical context.
- Specialist Matching and Review: RubiconMD’s routing engine assigns the case to an available specialist in the requested subspecialty, who evaluates the clinical attachments and formulates evidence-based diagnostic and therapeutic recommendations.
- Chart Write-Back and Action: The completed specialist report is written back into the originating EHR as a structured document or PDF attachment (mapped to US Core clinical note standards), allowing the PCP to adjust the care plan or order pre-visit diagnostics if an in-person referral remains necessary.
2. Interprofessional Consultation CPT Coding (99451 and 99452)
For fee-for-service Medicare, Medicaid programs with eConsult coverage, and commercial payers, asynchronous electronic consultations are billed using the American Medical Association (AMA) CPT Interprofessional Telephone/Internet/Electronic Health Record Consultations code family:
| CPT Code | Billing Clinician | Time Threshold & Modality | Documentation Requirements |
|---|---|---|---|
| CPT 99451 | Consulting Specialist | 5 or more minutes of medical consultative evaluation and management via EHR/internet | Written report transmitted to the treating/requesting practitioner; requires no face-to-face specialist visit within the next 14 days. |
| CPT 99452 | Treating / Requesting PCP | 16–30 minutes preparing for the referral and/or communicating with the specialist | Verbal/written patient consent documented in chart, clinical question summary, and integration of specialist advice into care plan. |
| CPT 99446–99449 | Consulting Specialist | 5–30+ minutes of consultative analysis culminating in both verbal and written reports | Used when synchronous verbal follow-up accompanies the written eConsult summary. |
3. Health Services Research and Value-Based Care Evaluation
Health services researchers and safety-net consortia (including evaluations supported by the California Health Care Foundation and academic medical centers) analyze eConsult utilization data to measure:
- Referral Avoidance Rates: The proportion of eConsults in which the PCP reports that an initially planned face-to-face specialty visit was safely avoided (commonly 70% to 80% of cases managed in primary care).
- Specialty Wait-Time Compression: Reduction in days from clinical question onset to specialist input compared with multi-week or multi-month outpatient specialty clinic backlogs.
- Educational Spillover: Longitudinal improvements in primary care clinicians’ ability to manage recurring specialty conditions independently.
Frequently Asked Questions
What is RubiconMD?
RubiconMD is an asynchronous electronic consultation (eConsult) platform acquired by Oak Street Health that enables primary care clinicians to submit patient clinical questions and diagnostic data to board-certified specialists across more than 140 subspecialties and receive written management guidance within hours.
How is RubiconMD used in clinical research and healthcare?
Healthcare organizations use RubiconMD inside their EHRs to obtain rapid specialist input, avoid unnecessary in-person referrals, and optimize pre-referral workups in safety-net and value-based care settings, while health services researchers use its consultation logs to study specialty access disparities, referral avoidance, and total cost of care.
