The full answer
Plan management is a specific provider service type — you must register separately or add it to an existing registration. The steps: 1) Build policies covering plan holding, financial management, banking controls, record-keeping and reporting, 2) Engage an Approved Quality Auditor for a Certification audit (higher-risk service type), 3) Undergo Stage 1 (desk review) and Stage 2 (site visit), 4) Close any non-conformities within 90 days, 5) Receive your provider number with 'Plan Management' scope. Plan management is highly profitable — charge $35-$55/participant/month. Most active plan managers manage 100-500 participants. The compliance burden is audits every 3 years plus monthly reconciliation.
