Maryland EVV Compliance

Maryland Mandates ISAS for EVV.
There's No Alternative Accepted.

Maryland's State Mandated model requires all Medicaid home care agencies to use ISAS — the In-Home Supports Assurance System — directly. Unlike open or hybrid states, alternative EVV vendors are not accepted in Maryland. CareBravo manages ISAS compliance as delivered operational work.

Maryland's State Mandated model is different from open or hybrid states. In Texas or California, agencies can use third-party EVV capture tools. In Maryland, ISAS is the required system — for both data capture and aggregation. Agencies that operate in multiple states and are accustomed to open-model EVV flexibility must adjust their approach for Maryland.

How Maryland's Model Works

ISAS Is Both Capture and Aggregator

Most states separate the EVV capture method (how caregivers check in and out) from the EVV aggregator (where the data goes). In open or hybrid states, an agency can use a third-party mobile app to capture the visit and submit that data to the state aggregator. Maryland doesn't work this way.

ISAS is Maryland's state-developed EVV platform. It is both the capture interface and the aggregation point. Caregivers must use ISAS's own telephony system or ISAS's mobile app to check in and out. Third-party capture tools — even ones that can submit to other state aggregators — are not accepted as substitutes for ISAS in Maryland.

This means Maryland agencies need to ensure every caregiver is provisioned in ISAS, trained on ISAS's specific check-in process, and using ISAS's designated capture method for every qualifying visit. Exceptions in ISAS — the same categories as any state: missed check-ins, location discrepancies, time mismatches — must be resolved in ISAS before billing.

CareBravo manages the ISAS setup, exception monitoring, and exception resolution as delivered operational work for Maryland agencies.

The Real Cost

ISAS Exceptions Block Maryland Billing

Unresolved ISAS exceptions block billing for the affected visits — the same mechanism as any state EVV system. For a 30-patient Maryland agency, a week's exception backlog typically represents $800–$1,500 in delayed revenue. CareBravo manages exception resolution daily so Maryland agencies receive billing-ready outputs without a separate reconciliation step.

Questions

Maryland EVV — Common Questions

No. Maryland's State Mandated model requires direct use of ISAS for both EVV capture and aggregation. Unlike open or hybrid states where agencies can choose a third-party capture tool that submits to the state aggregator, Maryland requires caregivers to check in and out using ISAS's own telephony or mobile application. Third-party EVV vendors are not accepted as a substitute for ISAS in Maryland.

ISAS — the In-Home Supports Assurance System — is Maryland's state-developed EVV platform, administered through the Maryland Department of Health (MDH). It serves as both the capture interface and the aggregation point for all Maryland Medicaid home care EVV records. All qualifying personal care and home health aide visits must be verified through ISAS before claims can be processed.

Federal law requires EVV for all Medicaid-funded Personal Care Services and Home Health aide visits. Maryland's HCBS waiver programs — including the Community Pathways Waiver, Community Supported Living Arrangements (CSLA) Waiver, and Home and Community-Based Options Waiver — require EVV through ISAS for qualifying home-based services. Verify specific service code requirements with MDH.

CareBravo integrates with state-mandated EVV systems including ISAS, managing caregiver setup, exception monitoring, resolution workflows, and Maryland Medicaid billing readiness as delivered operational work. Maryland agencies receive billing-ready outputs without managing the ISAS exception queue themselves.
