Published Medicaid fee-for-service schedule amounts, not a coverage or eligibility guarantee. Managed-care plan rates can differ. Where no prior-authorization flag is shown, the state does not publish one. Rows marked * are representative published variants or methodology-derived rates. "--" in the prior-auth column means the state publishes no PA flag.
