The U.S. population is aging rapidly. According to the Population Reference Bureau, the number of Americans age 65 and older is projected to grow from 58 million in 2022 to 82 million by 2050—an increase of nearly 47%. This demographic shift is driving sustained demand for comprehensive, home-based healthcare services. Home health agencies provide high-quality, patient-centered care in the comfort of the patient’s home or community setting.
The Centers for Medicare & Medicaid Services (CMS) has established specific requirements that apply to all providers billing Medicare for home-based care. Home health agencies must meet specific eligibility, documentation, and home health medical billing and coding requirements when submitting claims to for reimbursement. Professional medical billing services play a critical role in this context because Medicare home health reimbursement rules are complex and errors can directly impact both agency revenue and compliance.
In this post, we examine CMS home health billing guidelines, including the impact of the CMS-1828-F CY 2026 Home Health Prospective Payment System Final Rule.

Understanding Medicare Home Health Claim Documentation for Billing
Medicare covers part-time, medically necessary skilled home health services for homebound beneficiaries with a certified physician’s order, under Parts A and B. Covered services include skilled nursing, physical/occupational/speech therapy, medical social services, and part-time home health aide assistance. This may involve wound treatment, medication management, chronic condition monitoring, and rehabilitation. The program’s purpose is to restore or maintain function, support independence, prevent avoidable hospitalizations, and improve overall quality of life—provided the services are medically necessary and intermittent rather than full-time.
Medicare home health medical billing involves submitting claims for services provided to homebound patients under a physician-certified plan of care. Medicare has established detailed rules to govern billing for home health services to ensure that care is medically necessary, properly documented, and appropriately reimbursed. Under CMS guidelines, home health agencies must meet specific eligibility, documentation, and coding requirements when submitting claims for reimbursement.
HCPCS codes for supplies and non-drug items are updated twice a year, while drug codes are updated four times a year. Revenue codes must be reported along with HCPCS codes to accurately identify the department or type of service provided. For example, 042X is used for physical therapy, 043X for occupational therapy, and 055X for skilled nursing services. Using the appropriate combination of revenue and HCPCS codes helps ensure proper classification of services and accurate Medicare reimbursement.
Medicare home health billing requires submission of a Notice of Admission (NOA) within 5 days of the start of care, using a 30-day period of care structure under the Patient-Driven Groupings Model (PDGM). Claims must include a physician-certified plan of care, documented homebound status, and OASIS assessments, with payments adjusted for patient acuity and geographic wage differences.
Key Medicare Home Health Billing Rules for 2026
When billing for services, providers must follow specific Medicare’s to ensure that care is medically necessary, properly documented, and eligible for reimbursement.
Patient Eligibility Requirements
For Medicare to cover home health services, the patient must meet several eligibility criteria:
- be under the care of a physician, nurse practitioner or physician assistant
- be homebound, meaning leaving home requires considerable effort or assistance
- require intermittent skilled nursing care, physical therapy, speech-language pathology services, or continued occupational therapy
Physician Certification and Plan of Care
Medicare requires a physician or qualified practitioner to certify that the patient is eligible for home health care. This certification must confirm that the patient is homebound, requires skilled services, and has a regularly updated plan of care that outlines the type and frequency of services needed.
Face-to-Face Encounter Requirement
The patient must have a documented face-to-face or in-person encounter or approved telehealth visit with a physician or allowed practitioner within the required timeframe before or shortly after the start of home health services. The medical record clearly document that the encounter relates to the reason the patient requires home health care.
Low Utilization Payment Adjustment (LUPA)
If the number of visits provided during a 30-day care period falls below a certain threshold, Medicare applies a Low Utilization Payment Adjustment (LUPA). In such cases, the home health agency is paid per visit instead of receiving the full episode payment. This makes it important for providers to carefully track visit counts and document services accurately.
Documentation and Compliance
Thorough Medicare home health claim documentation is essential to support every billed service. Accurate documentation of the patient’s condition and services provided is essential to support the codes selected. Home health agencies must maintain records of:
- Visit notes: Must include details of each visit such as the nature of the service, duration, and patient response.
- Physician orders: All services must be supported by a signed plan of care by a certified physician.
- Medical necessity: Home health billing codes must align with the patient’s clinical status as documented in the OASIS assessment
- OASIS (Outcome and Assessment Information Set): Standardized data collected to assess patient needs, which directly influences reimbursement, especially regarding the assessment completion date (MO090)
Incomplete documentation is one of the most common reasons for claim denials or audits.
Quality Reporting and Value-Based Payment
Home health providers must also comply with the Home Health Quality Reporting Program and the expanded value-based purchasing model. Performance on quality measures can influence payment adjustments and public reporting of agency performance.
Payment under the Home Health Prospective Payment System
Medicare reimburses home health agencies under the Home Health Prospective Payment System, which uses the Patient-Driven Groupings Model to determine payment for each 30-day period of care. Payment is based on factors such as the patient’s clinical characteristics, functional limitations, and comorbidities. Accurate documentation and coding are essential to ensure that patients are assigned to the correct payment group.
The CMS-1828-F CY 2026 Home Health Prospective Payment System Final Rule impacts various areas of home health billing by providers, especially Medicare-billing home health agencies. Medicare home health billing changes in 2026 include:
- Payment rates – Claims submitted under the Home Health Prospective Payment System (HH PPS) will be reimbursed at slightly lower overall Medicare rates. Agencies must ensure accurate coding and documentation to maximize appropriate payment under the updated rate structure.
- Case-mix and visit thresholds – The Final Rule updated groups and thresholds, influencing payment amounts. Providers must code clinical and functional assessment data more accurately to ensure the correct group and payment tier.
- Face-to-face compliance – The updated Medicare home health billing guidelines 2026 expand which practitioners can perform the required face-to-face encounter. To avoid claim denials, home health agencies must confirm that the face-to-face encounter is completed by an eligible provider per the updated rule.
- Quality reporting – CMS removes certain measures/data elements from the HH QRP (e.g., COVID-19 vaccine status and several assessment items. Report required data correctly. Providers must update quality reporting submissions to reflect this measure removal, which affects public quality and value-based pay.
- Value-based purchasing – New quality measures now influence payment adjustments. Billing and clinical documentation teams need to support quality outcomes tied to these new measures.
- Provider enrollment – CMS expands provider enrollment rules. Agencies must tighten enrollment maintenance and compliance monitoring to avoid retroactive revocation.
