Coverage Criteria for Private Duty Nursing and Medically Fragile Day Care
Private Duty Home Nursing — Initial criteria
Covered when ALL of the following are met:
For Medicare Advantage members, LCDs apply where relevant; PDN services must be ordered following a face-to-face visit with recertification every 60 days by the ordering provider.
Medically Fragile Day Care
Covered when ALL of the following are met:
Transportation to/from facility is family's responsibility; one day of medically fragile day care is equivalent to 8 hours of private duty nursing. If member unable to attend due to acute illness, up to 8 hours of nursing per day in the home may be considered after 72 hours of illness.
Home Nursing for Patients on Ventilators
Ventilator management covered with conditions:
After stabilization, medically necessary nursing hours per day will decline as family/caregiver is instructed on routine ventilator care.
PDN Medical Necessity Criteria
Covered when ALL of the following are met
Physician orders and progress notes must document frequent assessments and show changes/adjustments have been made at least monthly.
A nurse may accompany the member for normal life activities (e.g., child attending school) only if medical needs meet PDN criteria; normal life activities do not include receiving care in medical facilities.
Private duty nursing (PDN) is not covered when the member is receiving care in a licensed inpatient or residential setting. Examples include an acute inpatient hospital, inpatient rehabilitation, skilled nursing facility (SNF), intermediate care facility, or when the member is a resident of a licensed residential care facility. (PDN coverage is intended for services delivered in the member’s private residence and does not apply while the member is institutionalized.)
PDN is not considered medically necessary solely because no caregiver is available to assume responsibility. Similarly, the need for nursing care only to enable participation in activities outside the home (for example, attending school) is not, by itself, a basis to authorize PDN or to expand PDN hours; the member’s medical needs must meet PDN criteria.
Services that can be provided safely and effectively by a nonclinical person do not become skilled nursing services merely because a caregiver is unavailable. If the member’s condition is stable, continuous licensed nurse attendance is not required, or hands‑on nursing interventions are unnecessary, the care is considered custodial and is not PDN.
PDN is not authorized for family convenience, solely because a caregiver is absent or unwilling, or merely to allow a family member to work or attend school. Likewise, PDN is not for routine participation in activities outside the home unless the member’s medical condition independently meets the criteria for PDN; PDN does not cover services provided while the member is receiving care in other medical settings (inpatient, outpatient, physician’s office, etc.).

Orders, Authorization, Documentation, and Denial Triggers
Ordering and Recertification Requirements
Ordering and recertification: Private Duty Nursing (PDN) must be ordered by the member’s primary care and/or treating physician as part of a treatment plan following a face-to-face visit when Medicare rules apply. Orders must include physician approval of a written treatment plan with short- and long-term goals. For Medicare Advantage members, the ordering provider must recertify every 60 days. Agencies/providers must be authorized to provide PDN and participate with traditional Medicare where applicable.
- Physician order required (MD/DO)
- Written treatment plan with short- and long-term goals
- Medicare: face-to-face visit and recertification every 60 days
- Agency/provider must be licensed and participate with Medicare when applicable
Prior Authorization / Qualification
Prior authorization / qualification: PDN is medically necessary only when the member has skilled needs, is homebound, requires skilled care exceeding intermittent visits, and placement of nursing is to meet clinical needs (not convenience). Services must be part of a short-term home care plan that leads to caregiver training and the member must be engaged in case management. Case managers should evaluate instability, frequency of skilled needs, caregiver ability, and plan for weaning as condition stabilizes.
- Member must have skilled needs and be homebound
- Care plan must aim to train caregiver(s) and transition care
- Case management involvement required
- Consider stability, number of skilled needs, and caregiver abilities when authorizing hours
Weaning and Step‑Down Expectations
Weaning / step‑down expectations: PDN is intended as short‑term, skill‑based support with the explicit goal of training the primary caregiver and reducing nursing hours as the member improves. Case managers should set and communicate expectations about regression of nursing hours and eventual termination of services and ensure caregiver training and competency are documented.
- Plan should include timeline/expectations for reduction of nursing hours
- Document caregiver training and demonstrated competency
- Case manager to coordinate input from hospital, agency, and treating physicians
Required Documentation and Orders
Required documentation and orders: The attending physician must order PDN as part of a treatment plan and approve a written treatment plan with specific goals. Documentation must show services are medically necessary, within nursing scope of practice, performed by a licensed nurse, provided in the member’s private residence, and that the member’s condition is unstable requiring frequent assessments and plan changes.
- Physician order and written treatment plan with goals
- Services performed by licensed RN or LPN and within scope of practice
- Documentation of medical necessity and that needs cannot be met by intermittent skilled nursing visits
- Evidence of instability and frequent nursing assessments with plan changes
Progress Notes and Ongoing Documentation
Progress notes and ongoing documentation: Nursing and adjunctive therapy progress notes must document frequent assessments, interventions, and adjustments to the plan of care. Physician orders should reflect changes or adjustments at least monthly. PDN eligibility requires documentation that needs could not be met through intermittent skilled nursing.
- Progress notes documenting frequent assessments and care plan adjustments
- Physician orders updated at least monthly to reflect changes
- Documentation that PDN is required rather than intermittent skilled visits
Triggers for Denial / Not Medically Necessary
Triggers for denial / Not medically necessary: PDN is not medically necessary when the service is solely for caregiver respite or convenience, to allow family to work or attend school, for maintenance or custodial care, when the member is in an inpatient or licensed residential facility, or solely because no caregiver is available or willing to assume responsibility. PDN is also not indicated solely to enable participation in activities outside the home.
- Not covered if primary purpose is caregiver respite or convenience
- Not covered solely to allow family/caregiver to work or attend school
- Not covered for maintenance or custodial care (see criteria for transition to maintenance)
- Not covered if member is in acute inpatient, inpatient rehab, SNF, intermediate care facility, or licensed residential care facility
- Not medically necessary solely because no caregiver is available or willing to assume responsibility
- Not authorized solely to enable participation in outside‑home activities
Operational Clarifications
Operational note: PDN may accompany a member for normal life activities (e.g., school) when medically required, but coverage does not extend to services received in other medical settings. Ensure orders and documentation justify PDN during outside‑home activities.
- Nurse may accompany member for normal life activities when criteria met
- Coverage excludes PDN while member receives care in inpatient/outpatient medical settings
- Orders must justify PDN during activities outside the home
Key Definitions
Background
Private duty nursing (PDN) is continuous, one‑on‑one skilled nursing care provided in the member’s home by a licensed nurse (RN or LPN), typically prescribed hourly for tasks that require ongoing professional nursing assessment and intervention. PDN is distinct from intermittent home health nursing visits and from non‑skilled caregiver or sitter services; it is intended for members whose condition is unstable, requires frequent nursing assessments and frequent changes to the plan of care, and cannot be met by periodic skilled visits or nonclinical caregivers.
