About BH Resource Solution
The Behavioral Health Resource Solution is published by The Vanguard Solution as a public, no-login reference for the people who have to get behavioral health services documented, coded, authorized and paid.
What is here
1,879 topics across 12 categories: procedure codes, diagnosis coding, payer policies, billing and reimbursement, levels of care, clinical assessments, documentation, compliance and accreditation, professional organizations, professional licensing, state requirements and industry guidance. The 2026 Aetna psychiatry coding guide is published in full alongside the library, with its authenticated rate, diagnosis, guideline and CCI tables intact.
How to use it
Treat every topic as orientation, not adjudication. Coverage, authorization and payment depend on the member's product, eligibility, network, contract and documentation on the date of service. Each topic keeps the publisher's own link so the current rule can be confirmed at the source.
Corrections
Requirements move. If a topic conflicts with what a payer, state agency or accreditor currently publishes, the publisher is right and this library needs updating — the linked source is the arbiter.
