IMLC.

An expedited licensure pathway across 38 states plus DC plus Guam.

The Interstate Medical Licensure Compact is an interstate-statutory agreement that provides an expedited pathway for eligible physicians to obtain licensure in multiple participating states ¹ . The compact does not issue licenses itself. Each participating state's medical board issues a license based on the IMLC's verification work. The process is faster than applying individually to each state but does not waive any state's licensing fee. The pathway is open to physicians who hold an unrestricted full license in a designated state of principal license (SPL), meet ABMS board-certification or equivalent criteria ⁷ , have no disciplinary history, have no active investigations, hold no DEA controlled-substance restrictions, and pass a fingerprint-based criminal background check.

As of 2024, the IMLC is operational in 38 U.S. states plus the District of Columbia and Guam, with additional states pending implementation. The list of participating states updates as state legislatures enact the compact statute. California is a notable non-participant in the active IMLC; physicians seeking California licensure follow the Medical Board of California's independent application process. The Federation of State Medical Boards maintains a related map and provides the underlying verification infrastructure for member boards ² . Practices planning multi-state telehealth expansion check the current participating-state list before scoping the SEO architecture; non-participating states require independent licensure timelines.

Active licensure in the patient's state at the moment of service.

AMA Code of Medical Ethics Opinion 1.2.12 governs ethical practice in telemedicine ³ . The substantive requirement for cross-state telehealth marketing is continuity of care: the attending physician must hold active licensure in the state where the patient sits at the moment of service. The opinion also addresses informed consent, privacy protection consistent with in-person standards, and the physician's responsibility to ensure technical and clinical competence in the telemedicine modality.

The continuity-of-care requirement maps directly to the SEO architectural constraint. A telehealth practice cannot target every state's local-pack queries from a single-license footprint. The geographic targeting in site architecture has to align with the actual state-license footprint of the attending physicians. The architectural surface is verifiable: a state medical board compliance scanner can cross-reference the practice's per-state landing pages against the licensed-state list at NPPES and at the board's own licensure database ⁴ . Drift between marketing claims and the verified licensure footprint surfaces as an enforcement target.

Per-state pages keyed to the licensure footprint. areaServed populated honestly.

The architectural pattern: per-state landing pages exist only for states where at least one attending physician holds active licensure. Google Business Profile local-pack architecture aligns with physical operating locations rather than every targeted-query state; a fully-virtual telehealth practice without physical locations runs primarily on the per-state landing pages and the schema layer. Schema.org areaServed is populated with the actual licensed-state list rather than aspirational coverage ⁶ . Physician author bylines surface the per-state licensure status alongside the ABMS certification.

A multi-physician telehealth practice routes per-state queries to the physician licensed in that state. The architecture is verifiable. State medical boards actively monitor advertising and digital marketing for unlicensed-practice signals. A practice's website targeting a state's geographic queries without active licensure in that state surfaces as an enforcement target. The boards rely on patient complaints, peer reports, and active scanning of advertising surfaces; some boards retain compliance staff who scan SERPs and social media for jurisdictional violations. Enforcement responses range from a cease-and-desist letter to formal investigation to disciplinary action against the physician's primary-state license.

A separate overlay on top of state medical licensure.

DEA registration is separate from state medical licensure. A physician's DEA number is registered to a specific state; controlled-substance prescribing across state lines requires either separate state-by-state DEA registrations or an exception under the Ryan Haight Online Pharmacy Consumer Protection Act for telemedicine prescribing under specific conditions ⁵ . The IMLC streamlines state medical licensure but does not address DEA registration directly.

Practices that include controlled-substance prescribing as part of their telehealth offering scope the DEA-registration footprint alongside the state-licensure footprint. The SEO architecture for controlled-substance-prescribing telehealth practices reads narrower than the licensure footprint when DEA registration constraints apply. The discipline is encoded on the per-state landing-page surface (which controlled-substance categories the practice can prescribe in this jurisdiction, which it cannot) rather than in a sitewide claim about controlled-substance availability. The architecture supports defensible posture under both AMA Opinion 1.2.12 and DEA enforcement.

The IMLC constraint sits inside the broader Medical SEO architecture for telehealth practices at Praxis. The licensure footprint is the load-bearing input; the schema layer, the GBP architecture, and the per-state landing pages all align against it.
