Which platform fits your team
When to use Castle Connolly
Use Castle Connolly when the audience needs a curated shortlist of peer-recognized specialists — particularly for complex or elective procedures where patients are willing to travel for a recognized expert. The list is selective and signals peer regard rather than patient volume.
When to use Healthgrades
Use Healthgrades for broad provider discovery across any specialty, geography, and insurance network. Its review volume and insurance filters make it the practical starting point for most patient searches, even if it lacks peer-nominated selectivity.
Common questions
- Is a Castle Connolly Top Doctor designation officially recognized?
- Castle Connolly is a private company — its Top Doctor designation is a recognition program, not a regulatory credential. It is peer-influenced and carries brand recognition in physician circles, but it is not issued by a medical board, CMS, or any government agency. For regulated credentials, state medical board licensure and ABMS board certification are the authoritative sources.
- How does Castle Connolly select Top Doctors?
- Castle Connolly uses a peer nomination process — physicians nominate colleagues — followed by a credentialing review by Castle Connolly's staff. The selection criteria are published at a high level on their website, but the per-nomination decision process is not publicly auditable.
- Can Castle Connolly or Healthgrades data be used in a credentialing application?
- Neither is a credentialing source for regulatory or billing purposes. For credentialing, the authoritative sources are state medical board licensure (varies by state) and Medicare enrollment status via CMS PECOS. OIG LEIE provides the federal exclusion check. These are the federal primary sources for any compliance-grade credentialing workflow.
- Does being on Healthgrades guarantee a physician is in good standing?
- No. Healthgrades is a listing and review platform, not a licensure authority. A provider can appear on Healthgrades while under disciplinary action or with a lapsed license. State medical boards and CMS PECOS enrollment status are the authoritative sources for good-standing determination.
