Hypertensive and diabetes-related home management programs are covered when criteria are met.
Program wording and visit counts were revised historically; case-rate references were removed.
The policy explicitly identifies several services provided by home health vendors that are considered not medically necessary when billed as part of obstetrical home care. These include multiple repeat courses or intermittent injections of betamethasone, management of multiple gestations (refer to individual program risk factors), continuous heparin infusion therapy, member-administered nonstress tests or fetal heart rate monitoring, management of preterm prelabor rupture of membranes (PPROM), preterm labor management, and 17-hydroxyprogesterone caproate (Makena) injections.
Preeclampsia with severe features is explicitly excluded from home management and requires inpatient care. The policy notes that home visits and remote monitoring apply to selected cases such as preeclampsia without severe features, but members with preeclampsia with severe features are not eligible for home management and should be managed in an inpatient setting.
This clinical policy is a guidance document to assist in coverage decision-making and benefit administration; it does not constitute medical advice, medical treatment, or medical care and is not intended to dictate how providers practice. Providers must exercise professional medical judgment in caring for members/enrollees and are solely responsible for medical advice and treatment decisions.
Services listed in the policy under exclusions are treated as not medically necessary when provided by a home health vendor. These specifically include: repeated betamethasone courses or intermittent antenatal corticosteroid injections, home management for multiple gestations, continuous heparin infusion, patient-administered NST or fetal monitoring, PPROM management, preterm labor management, and 17-hydroxyprogesterone caproate (Makena) injections.
Administration of 17-hydroxyprogesterone caproate (17-OHPC, Makena) nursing visits was removed from the policy criteria. The background and revision notes record ACOG’s statement and the FDA action proposing withdrawal of 17-OHPC for prevention of recurrent preterm birth; following these developments the policy removed Makena administration visits from covered home health services.

Authorization, Documentation, and Billing Requirements
Prior Authorization Required for Home Infusion and Skilled Nursing Services
Authorization is required for home infusion (e.g., metoclopramide or ondansetron) and for skilled nursing home visits that deliver infusion or hydration therapy. Home infusion and hydration visits are considered medically necessary only when the member meets the policy clinical criteria, including prior trial and failure of conservative therapies and any ACOG-recommended stepwise antiemetic management where applicable.
- Prior authorization required for infusion and hydration home visits when billed by a home health vendor
- Include documentation of the trial and failure of conservative therapies (oral/rectal medications and/or non-pharmacologic treatments) before authorization
- Ordering provider must document ACOG-tiered antiemetic escalation prior to infusion when applicable
Prior Authorization Procedures
Prior authorization requests and any re-authorization requests must follow the Health Plan’s established plan-level administrative procedures. The clinical policy is effective as determined by the Health Plan; check the plan portal or provider manuals for submission instructions, required forms, and timelines.
- Follow plan procedures for prior authorization submission and for any required precertification or notification
- Confirm the effective date and any plan-specific requirements on the Health Plan provider site
Reauthorization and Documentation Requirements
Re-authorization for continued infusion or hydration requires contemporaneous reassessment by the ordering provider. The provider must document that the member has been reassessed since the prior authorization and provide clinical justification for continued home-based services.
- Ordering provider must document the reassessment and continued clinical need when requesting continuation/re-authorization
- Include clinical notes demonstrating response to prior therapy and reason ongoing home infusion or hydration is required
Not Medically Necessary Services (Denial Risk)
The following services provided by a home health vendor are considered not medically necessary when billed in this context and may be denied: multiple repeat courses of betamethasone; multiple gestation management (refer to specific programs); continuous heparin infusion therapy; member-administered nonstress tests or fetal heart rate monitoring; PPROM management; preterm labor management when not meeting program criteria; and 17-hydroxyprogesterone caproate (Makena) injections.
- Betamethasone via multiple repeat courses or intermittent injections — not medically necessary
- Continuous heparin infusion therapy — not medically necessary
- Member-administered fetal monitoring/nonstress testing — not medically necessary
- 17-hydroxyprogesterone caproate (Makena) injections — not medically necessary
- Other listed services in policy II may be excluded from coverage
Coding Inclusion Does Not Guarantee Coverage
Inclusion of procedure, HCPCS, or CPT codes in policy background or coding tables is for reference only and does not guarantee coverage. Providers must rely on current coding guidance and verify coverage prior to claim submission.
- Inclusion or exclusion of codes in this policy does not guarantee coverage
- Reference the most up-to-date professional coding guidance and plan-specific billing instructions before submitting claims
Denial/Truncation Risk from Benefit Limits and Contract Terms
Coverage and payment remain subject to all plan terms, conditions, exclusions, limitations, and applicable state or federal requirements. Services may be denied or truncated based on benefit limits, contract terms, or regulatory constraints.
- Verify member benefits, eligibility, and any applicable limits prior to service delivery
- When state Medicaid rules conflict with this clinical policy, state Medicaid provisions take precedence for Medicaid members
Contractual and State Documentation Obligations
Providers are contractually obligated to comply with Health Plan documentation requirements and applicable state regulations. The clinical policy does not replace plan-level administrative rules; providers remain responsible for maintaining required medical records and for regulatory compliance.
- Maintain complete medical records supporting medical necessity, reassessments, and authorization requests
- Comply with state Medicaid manual requirements when applicable
Program Description and Scope
Obstetrical homecare programs provide risk assessment, education, case management and in‑home clinical services for pregnant members at increased risk. Typical program components include an obstetrical nurse assessment performed in the home when delivered with specified services (e.g., infusion therapy, hydration, diabetes or hypertensive disorder management, dietary analysis); condition‑specific monitoring such as remote blood pressure measurement for hypertensive disorders; targeted interventions including IV hydration (commonly 1–4 liters per visit) and home infusion of antiemetics or insulin when indicated; and coordination of care with the ordering provider and obstetric team.

Clinical guidance and evidence considered in developing this policy include ACOG practice guidance and committee opinions along with peer‑reviewed literature. Representative sources cited in the reference list include ACOG Practice Bulletin No. 189 on Nausea and Vomiting of Pregnancy and ACOG Committee Opinion documents (for example, outpatient antenatal fetal surveillance guidance). The policy’s reference list and background review reflect these and other clinical publications used to inform criteria and program design.
This policy is owned by the Health Plan and was developed by clinicians and reviewers. It is consistent with generally accepted standards of medical practice at the time of approval but does not supersede contract terms. For Medicaid members, state Medicaid coverage provisions take precedence where they conflict with this policy; for Medicare members, applicable NCDs, LCDs and Medicare Coverage Articles should be reviewed prior to applying these criteria. The Health Plan retains the right to change or withdraw this policy and plan‑level administrative procedures may require prior authorization as determined by the Health Plan.
