Massachusetts - Skilled Nursing Services — Licensing, Medicaid Enrollment and Startup Requirements

Last reviewed: 2026-09-10

MassHealth purchases intermittent skilled nursing and continuous skilled nursing (CSN) services under 130 CMR 403.000 and 130 CMR 438.000, requiring providers to enroll through the Provider Online Service Center (POSC). The Massachusetts Department of Public Health (DPH) does not issue state-level licenses for home health agencies; instead, the structural gate to entry is obtaining Medicare certification from the Centers for Medicare & Medicaid Services (CMS) before MassHealth will execute a Home Health Agency provider agreement.

Agencies delivering these RN and LPN services must navigate federal survey processes rather than state licensure, alongside mandatory prior authorization thresholds for visits exceeding 30 per calendar year. Approval requires submitting a complete MassHealth provider application, demonstrating compliance with 101 CMR 350.00 rate structures, and maintaining active standing with the Massachusetts Board of Registration in Nursing for all clinical staff.

1. Service Definition and Scope

Massachusetts defines these services under 130 CMR 403.000 as nursing services provided by a licensed nurse that are necessary to provide targeted skilled nursing assessment for a specific member medical need, and/or discrete procedures and treatments. These are delivered in the member's home under a physician's order.

The state distinguishes between intermittent visits (typically under two hours) and Continuous Skilled Nursing (CSN), which involves longer blocks of care. Maintenance programs that do not require the judgment and skill of a licensed therapist or nurse for safety and effectiveness are categorized separately.

• Intermittent Skilled Nursing Visits: Targeted skilled nursing assessment or discrete procedures typically lasting less than two consecutive hours.
• Continuous Skilled Nursing (CSN): Nursing care exceeding two continuous hours per visit, governed by 130 CMR 438.000.
• Nursing Services: The assessment, planning, intervention, and evaluation of goal-oriented nursing care requiring specialized knowledge.
• Maintenance Program: Repetitive services required to maintain function that do not require skilled clinical judgment.
• Prior Authorization Threshold: Mandatory prior authorization is required whenever services exceed 30 intermittent skilled nursing visits in a calendar year.

2. Regulatory and Oversight Agencies

Because Massachusetts does not have a distinct state license for home health agencies, oversight is split between federal Medicare certification bodies and state Medicaid enrollment authorities. The Department of Public Health (DPH) conducts surveys on behalf of CMS.

MassHealth acts as the primary payer and enrollment authority for Medicaid services, managing provider agreements and claims through its dedicated portal.

• MassHealth: Administers Medicaid provider enrollment, prior authorizations, and claims processing [https://www.mass.gov/topics/masshealth].
• DPH Division of Health Care Facility Licensure and Certification: Conducts Medicare certification surveys for home health agencies in Massachusetts [https://www.mass.gov/orgs/division-of-health-care-facility-licensure-and-certification].
• Centers for Medicare & Medicaid Services (CMS): Grants the federal Medicare certification required for MassHealth HHA enrollment [https://www.cms.gov].
• MassHealth Provider Online Service Center (POSC): The mandatory portal for submitting enrollment applications and billing claims [https://newmmis-portal.ehs.state.ma.us/EHSProviderPortal/].
• Massachusetts Board of Registration in Nursing: Issues and oversees the licenses of all RNs and LPNs delivering care [https://www.mass.gov/orgs/board-of-registration-in-nursing].

3. Gatekeeping Prerequisites: Who Can Even Apply

Massachusetts laws for the Department of Public Health do not include licensure of home health agencies. Therefore, the absolute structural precondition for enrolling as a standard MassHealth Home Health Agency is obtaining Medicare certification.

An agency cannot simply apply to MassHealth to provide intermittent skilled nursing without first securing a CMS Certification Number (CCN). If the agency also acts as an employment agency, it faces an additional state licensure gate from the Department of Labor Standards.

• State Licensure Exemption: The Massachusetts DPH explicitly does not license home health agencies, removing state licensure as a gate but replacing it with federal certification.
• Medicare Certification: A mandatory prerequisite; MassHealth requires standard Home Health Agencies to be Medicare-certified before a provider agreement is issued.
• Employment Agency License: Required from the Massachusetts Department of Labor Standards if the home health agency operates as an employment agency.
• National Provider Identifier (NPI): Must be obtained from NPPES before initiating any application in the MassHealth POSC.

4. Licensure and Certification Requirements

To meet the Medicare certification prerequisite, agencies must complete the federal enrollment process, which culminates in an unannounced on-site survey by the Massachusetts DPH Division of Health Care Facility Licensure and Certification.

Agencies must demonstrate compliance with federal Conditions of Participation (CoPs) for Home Health Agencies, including patient care standards, capitalization, and data reporting capabilities.

• CMS-855A Application: The initial Medicare enrollment application submitted to the regional Medicare Administrative Contractor (MAC).
• Capitalization Requirement: Agencies must prove sufficient initial reserve operating funds as dictated by CMS before survey approval.
• DPH Initial Survey: An unannounced on-site inspection conducted by DPH surveyors to verify compliance with federal CoPs.
• OASIS Transmission: Agencies must demonstrate the technical capacity to successfully transmit Outcome and Assessment Information Set (OASIS) data.

5. Medicaid Provider Enrollment

Once Medicare certification is secured, agencies apply to MassHealth via the Provider Online Service Center (POSC). Providers enroll under specific provider types depending on their service model.

The enrollment packet requires submission of the MassHealth Provider Agreement, proof of Medicare certification, and specific financial disclosures.

• Enrollment Portal: All applications must be submitted electronically through the MassHealth POSC.
• Provider Type 60: The specific MassHealth provider type designation for standard Home Health Agencies.
• Provider Type 38: The specific MassHealth provider type designation for Continuous Skilled Nursing Agencies.
• Data Collection Form: A mandatory MassHealth form detailing agency ownership, managing employees, and service locations.
• Electronic Funds Transfer (EFT): Mandatory enrollment form required by the Massachusetts Comptroller for claims payment.

6. Staffing, Training and Background Checks

Skilled nursing services must be delivered by clinicians holding active, unencumbered licenses from the Massachusetts Board of Registration in Nursing. Agencies are strictly liable for verifying credentials prior to patient contact.

Massachusetts mandates rigorous background screening, including state-specific Criminal Offender Record Information (CORI) checks for all personnel entering a member's home.

• RN Licensure: Must hold a current, active Registered Nurse license from the Massachusetts Board of Registration in Nursing.
• LPN Supervision: Licensed Practical Nurses must practice under the direct, documented supervision of a Registered Nurse.
• CORI Checks: Mandatory Criminal Offender Record Information checks must be cleared for all patient-facing staff before deployment.
• OIG Exclusion Screening: Agencies must screen all employees and contractors monthly against the federal LEIE database.

7. Documentation, Policies and Records

MassHealth enforces strict documentation standards under 130 CMR 403.000. Every skilled nursing visit must be supported by a physician's order and an individualized plan of care.

Clinical records must clearly delineate the medical necessity of the skilled intervention, the exact time spent in the home, and the member's response to treatment.

• Physician Orders: Written orders from a physician are required for all skilled nursing services and must be updated at least every 60 days.
• Plan of Care: An individualized care plan established by the RN in collaboration with the prescribing physician.
• Visit Notes: Contemporaneous documentation requiring time-in, time-out, clinical observations, and specific interventions performed.
• Verbal Order Follow-up: Any verbal request for changes in service authorization must be followed up in writing within two weeks.
• Record Retention: Clinical and billing records must be retained for a minimum of six years from the date of service or final payment.

8. Billing, Rates and Claims

Reimbursement rates for skilled nursing are established by the Executive Office of Health and Human Services (EOHHS) under 101 CMR 350.00 for home health and 101 CMR 361.00 for CSN. Claims are adjudicated through the MMIS.

Providers must secure prior authorization for high-utilization cases to avoid claim denials. Billing is conducted via 837I/837P EDI transactions or direct POSC data entry.

• Rate Authority: Rates are strictly governed by 101 CMR 350.00 (Home Health Services) and 101 CMR 361.00 (Continuous Skilled Nursing).
• Prior Authorization (PA): Mandatory via POSC for any intermittent skilled nursing visits exceeding 30 in a single calendar year.
• Unit of Service (Intermittent): Billed on a per-visit basis, typically representing an encounter of less than two hours.
• Unit of Service (CSN): Billed in 15-minute increments for continuous care blocks exceeding two hours.
• Claims Submission: Executed electronically via the MassHealth POSC or through approved clearinghouses using standard EDI formats.

9. Approval Sequence and Timeline

Because Massachusetts relies on Medicare certification as the primary gate, the timeline is heavily dependent on federal and MAC processing speeds, followed by DPH survey scheduling.

Only after the CMS Certification Number (CCN) is issued can the agency submit its MassHealth POSC application, which adds an additional processing window.

• Step 1: CMS-855A Submission: Application to the MAC, typically requiring 60-90 days for initial review and approval.
• Step 2: DPH Survey Scheduling: Awaiting the unannounced DPH Medicare certification survey, which can take 3-6 months depending on state backlog.
• Step 3: CMS Certification: Issuance of the CCN by CMS following a successful DPH survey and MAC finalization.
• Step 4: MassHealth POSC Application: Submission of the Medicaid enrollment packet, typically processed by MassHealth in 30-45 days.

10. Common Denials and Survey Findings

During DPH surveys and MassHealth post-payment audits, agencies frequently face citations for administrative lapses rather than clinical errors. Strict adherence to authorization thresholds is critical.

Failure to maintain continuous physician oversight on care plans is a primary driver of MassHealth claim recoupments.

• Missing Prior Authorization: Billing for the 31st intermittent visit in a calendar year without an approved PA on file in the POSC.
• Care Plan Lapses: Delivering services without a current, physician-signed 60-day plan of care update.
• Supervision Gaps: Failing to document required RN supervisory visits for LPNs delivering care in the home.
• CORI Violations: Deploying staff to a member's home before the mandatory state background check has been fully cleared and documented.
• Timekeeping Errors: Discrepancies between the billed units and the time-in/time-out documented in the clinical visit note.

11. Key Contacts and Resources

Providers must utilize official Commonwealth of Massachusetts resources for regulations, enrollment portals, and licensure verification.

The MassHealth Provider Service Center and the DPH Licensure Division are the primary technical assistance contacts for new applicants.
