Understanding Home Care Billing
Billing is consistently ranked the #1 operational challenge for home care agencies. Here is a high-level overview of the three primary revenue streams.
Private Pay
The simplest billing method. Clients or their families pay directly for services — no claims forms, no pre-authorizations, no waiting 60 days for reimbursement. You set your rates, send invoices, and collect payment. Most non-medical home care agencies start here, and many operate exclusively on private pay.
Medicare
Federal insurance covering skilled home health services for patients 65 and older (or those with qualifying disabilities). Medicare pays for skilled nursing, physical therapy, occupational therapy, speech-language pathology, medical social services, and home health aide services — but only when ordered by a physician and delivered by a Medicare-certified agency. Reimbursement follows the Patient-Driven Groupings Model (PDGM).
Insurance & Long-Term Care Insurance
Long-term care (LTC) insurance policies cover a range of home care services, from personal care to companion care. Billing insurance requires eligibility verification, benefit exhaustion tracking, pre-authorization, and submitting standardized claims (CMS-1500 paper or 837P electronic). Reimbursement typically takes 30–60 days and may involve Explanation of Benefits (EOB) reconciliation.
Private Pay Billing
Direct billing between your agency and the client. No insurance company middleman.
What Is Private Pay?
Private pay (also called "self-pay" or "out-of-pocket") means the client, their family, or a fiduciary (such as a trust or guardian) pays your agency directly for services rendered. There is no third-party payer involved — no claims to submit, no authorization to obtain, and no contractual rate schedule to follow.
For non-medical home care agencies that provide personal care, companion care, homemaker services, and respite care, private pay is often the dominant or sole revenue source. According to the Home Care Association of America (HCAOA), approximately 70% of non-medical home care revenue comes from private pay.
Setting Your Rates
Hourly rates for private-pay home care vary significantly by geography, service type, and local competition. Here are the current national benchmarks:
When setting your rates, consider:
- Your local market: research competitor rates within a 30-mile radius
- Service type: personal care (bathing, dressing) commands higher rates than companion care
- Shift length minimums: most agencies require a 3-4 hour minimum per visit
- Weekend and holiday differentials: 10-20% premium is standard
- Live-in care: typically billed at a flat daily rate ($250-$400/day) rather than hourly
- Your caregiver wages: aim for a billing-to-wage ratio of 1.5x to 2.0x to cover overhead and profit
Invoice Creation & Management
A clear, professional invoice is the foundation of timely payment. Every private pay invoice should include:
Send invoices on the same day each week or billing cycle. Consistency sets client expectations and reduces late payments. Most agencies bill weekly or biweekly, with payment due within 15 days.

Medicare Home Health Billing
Medicare is the largest single payer for home health services. Understanding its requirements is essential for any agency accepting Medicare patients.
Overview of the Medicare Home Health Benefit
Medicare Part A covers home health services for eligible beneficiaries. Unlike hospital or facility care, there is no copay or deductible for Medicare home health services — Medicare pays the agency directly based on a prospective payment model.
The Medicare home health benefit covers:
Patient Eligibility Requirements
For a patient to qualify for Medicare-covered home health services, all four conditions must be met:
1Homebound status
The patient must be confined to their home, meaning leaving home requires considerable and taxing effort. Occasional trips to the doctor, religious services, or adult day care do not disqualify a patient.
2Skilled care need
The patient must need skilled nursing care, physical therapy, occupational therapy, or speech-language pathology on an intermittent (not full-time) basis.
3Physician order
A physician or allowed practitioner must certify that the patient needs home health services, establish (or review) a plan of care, and perform a face-to-face encounter within the required timeframe.
4Medicare-certified agency
Services must be provided by a home health agency that is Medicare-certified (has a CMS Certification Number). Certification requires a state survey and compliance with the Conditions of Participation (CoPs).
Payment Model: PDGM & 30-Day Periods
Since January 2020, Medicare reimburses home health agencies under the Patient-Driven Groupings Model (PDGM). PDGM replaced the prior 60-day episode model with 30-day payment periods. Here is how it works:
30-Day Payment Periods
Each certification period consists of two 30-day payment periods. The agency receives a case-mix adjusted payment for each 30-day period based on patient characteristics, not the volume of visits provided.
Case-Mix Adjustment Factors
Payment is determined by five variables: admission source (community vs. institutional), timing (early vs. late in the episode), clinical grouping (based on principal diagnosis), functional impairment level (from OASIS), and comorbidity adjustment.
Low Utilization Payment Adjustment (LUPA)
If you provide fewer visits than the LUPA threshold (varies by clinical group, typically 2–6 visits per 30-day period), you receive a per-visit rate instead of the full case-mix payment. This is significantly less. Monitor LUPA thresholds carefully.
OASIS Assessments
The Outcome and Assessment Information Set (OASIS) is a standardized patient assessment required for all Medicare and Medicaid home health patients. OASIS data directly drives your PDGM payment — accurate completion is not optional, it is the foundation of your reimbursement.
OASIS assessments are required at these time points:
Claims Submission Process
Medicare home health claims are submitted as 837I (institutional) electronic claims to your regional Medicare Administrative Contractor (MAC). The process follows these steps:
Complete OASIS
Clinician completes the OASIS assessment and transmits it to CMS via the OASIS system.
RAP or NOA submission
Submit a Notice of Admission (NOA) within 5 calendar days of the start of care to establish the episode.
Deliver care
Provide skilled services per the plan of care during the 30-day payment period.
Submit final claim
At the end of the 30-day period, submit the final claim (Type of Bill 329 for the first period, 329 for subsequent).
Receive payment
MAC processes the claim against OASIS data, applies case-mix adjustments, and issues payment (typically 14-30 days).
Common Denial Reasons & How to Avoid Them
Missing or late face-to-face encounter
How to avoid: Ensure the physician encounter occurs within 90 days before or 30 days after the SOC date. Track this with automated reminders.
Homebound status not clearly documented
How to avoid: Document specific functional limitations that make leaving home a taxing effort. "Patient is homebound" is not sufficient — describe why.
Plan of care not signed by physician
How to avoid: Obtain the physician signature within 30 days of the SOC. Use electronic signature tools to speed this up.
Medical necessity not established
How to avoid: Clearly document the skilled need in every visit note. Connect each intervention to a specific, measurable care goal.
OASIS not transmitted or data mismatch
How to avoid: Transmit OASIS within 30 days of the assessment. Verify that diagnosis codes on the claim match the OASIS.
LUPA threshold not met
How to avoid: Track the LUPA visit threshold for each patient at the start of the 30-day period. If nearing the threshold, evaluate clinical need for additional visits.

Insurance & Long-Term Care Insurance Billing
LTC insurance policies can be a significant revenue stream, but the claims process requires precision and patience.
Overview of LTC Insurance Policies
Long-term care insurance (LTCI) policies are private insurance products that cover personal care, companion care, homemaker services, and sometimes skilled nursing when the policyholder meets benefit triggers. Unlike Medicare, LTCI policies:
- Cover non-medical personal care and companion services
- Have a daily or monthly benefit maximum (e.g., $200/day or $6,000/month)
- Include a lifetime maximum (e.g., $250,000 total) or benefit period (e.g., 3 years)
- Require the policyholder to meet benefit triggers (typically needing help with 2+ ADLs or cognitive impairment)
- Have an elimination period (waiting period) of 30-90 days before benefits begin
- Are issued by private insurance companies (Genworth, Mutual of Omaha, Northwestern Mutual, etc.)
Verifying Benefits & Eligibility
Before providing any services, verify the client's LTC insurance benefits. This is the single most important step in insurance billing. Skipping it leads to denied claims and unpaid services.
Verification Checklist
Pre-Authorization Requirements
Many LTC insurance policies require pre-authorization before services begin. This means you must submit a care plan or assessment to the insurance company and receive written approval before any billable services are provided. Without pre-authorization, claims may be denied retroactively.
Pre-authorization typically requires:
- A completed assessment showing the client meets benefit triggers (2+ ADL deficits or cognitive impairment)
- A physician statement or order (some carriers require this, others do not)
- A proposed plan of care with service types, frequency, and duration
- Provider credentials (agency license, bonding certificate, liability insurance)
Claims Submission: CMS-1500 & 837P
Insurance claims for home care services are submitted using either the CMS-1500 paper form or its electronic equivalent, the 837P (Professional) transaction. Most payers now require or strongly prefer electronic submission.
CMS-1500 / 837P Key Fields for Home Care
EDI Transactions Explained in Plain Language
Electronic Data Interchange (EDI) is how healthcare claims and related information flow between providers, clearinghouses, and payers. Here are the key transaction types you need to know:
This is your claim. It is the electronic version of the CMS-1500 form. You send it to the payer through a clearinghouse to request payment for services rendered.
You send a 270 to ask "Is this patient eligible for coverage?" The payer responds with a 271 that says "Yes, here are their benefits" or "No, this patient is not covered." This replaces phone calls to verify insurance.
You send a 276 to ask "What is the status of my claim?" The payer responds with a 277 that says "Received," "In process," "Paid," or "Denied with reason code X." This replaces calling the payer to check on claims.
This is the payer's payment explanation. It tells you exactly what was paid, what was denied, and why. It is the electronic version of the Explanation of Benefits (EOB). Use it to reconcile payments and identify denied line items.
Clearinghouse Integration Explained
A clearinghouse is a third-party intermediary that sits between your agency and the insurance payer. Think of it like a postal service for claims — you send your claim to the clearinghouse, it validates the data, reformats it if needed, and routes it to the correct payer.
What a clearinghouse does:
- Validates your claims for errors before they reach the payer (formatting, missing fields, invalid codes)
- Translates your claim into the payer-specific format required
- Transmits the claim electronically to the correct payer
- Returns acknowledgments (accepted or rejected) within 24-48 hours
- Receives and routes ERA (835) payment files back to your system
- Provides a dashboard to track claim status across all payers
Major clearinghouses used in home care include Availity, Change Healthcare (now Optum), Office Ally, Trizetto, and Waystar. Your billing software should integrate with at least one clearinghouse to automate the claims cycle.
ERA Reconciliation
When a payer processes your claim, they send back an Electronic Remittance Advice (ERA / 835 file) that details what was paid, adjusted, or denied for each line item. Reconciliation is the process of matching each ERA to the original claim and updating your accounts receivable.
During reconciliation, check for:
- Paid amounts matching expected contracted rates
- Denied line items with reason codes (CARC/RARC codes) and take corrective action
- Contractual adjustments (the difference between billed and allowed amounts)
- Patient responsibility amounts (copays, coinsurance, deductibles)
- Timely filing deadlines for appeals on denied claims (typically 60-180 days)
Common Insurance Billing Pitfalls
Medicaid Billing
Medicaid is a joint federal-state program, which means rules, rates, and requirements vary by state. Here is what every agency needs to know.
State-by-State Variation
Unlike Medicare, which is a uniform federal program, Medicaid is administered by each state individually. This means that every aspect of Medicaid home care billing varies by state:
EVV Requirements
The 21st Century Cures Act requires all states to implement Electronic Visit Verification (EVV) for Medicaid-funded personal care services and home health care services. EVV captures six data points for every visit: type of service, who received it, who provided it, date, time in/out, and location.
Many states now enforce "hard edits" that automatically deny Medicaid claims submitted without matching EVV data. If your agency bills Medicaid, EVV compliance is not optional.
Reimbursement Rates Overview
Medicaid reimbursement rates for home care services are set by each state and are generally lower than private pay or Medicare rates. Rates are published in the state's Medicaid fee schedule and may be updated annually.
Key considerations for Medicaid rates:
- Rates are non-negotiable (unlike private insurance, you cannot negotiate Medicaid rates)
- Some states use managed care organizations (MCOs) that may have different rates than fee-for-service
- Rate increases require legislative or regulatory action and are often years apart
- Supplemental payments or add-ons may be available for rural areas, specialized care, or overtime
- Always verify the current fee schedule before accepting Medicaid patients — rates change
Authorization Requirements
Most Medicaid home care services require prior authorization from the state or its managed care organization. Authorizations specify:

Follow these principles to maximize revenue, minimize denials, and keep your cash flow healthy.
Document Everything
Every visit should have a complete, signed visit note that includes services performed, time in/out, client condition, and any incidents. If it is not documented, it did not happen — and it will not be paid.
Verify Eligibility Before Every Service
For insurance and Medicaid clients, verify eligibility at the start of each authorization period and whenever there is a gap in service. Benefits can change, policies can lapse, and authorizations can expire without notice.
Submit Claims Within 24-48 Hours
The faster you submit claims after service delivery, the faster you get paid and the fewer errors accumulate. Daily claim submission should be the standard, not weekly or monthly batches.
Track Your Clean Claim Rate
A "clean claim" passes through the clearinghouse and payer without errors on the first submission. The industry benchmark is 95%+. If your clean claim rate is below 90%, you have a systemic billing process problem that needs immediate attention.
Automate Where Possible
Manual billing processes introduce errors and slow down cash flow. Automate claim generation from visit data, eligibility verification via 270/271 transactions, ERA posting, and payment reminders for private pay clients.
Conduct Regular Audits
Perform monthly billing audits: sample 10-20 claims per payer, verify documentation supports the billed services, check for under-coding (leaving money on the table) and over-coding (compliance risk). Quarterly, audit your entire A/R aging report.
Key Billing Metrics to Track
What gets measured gets managed. Monitor these five KPIs to keep your billing operation healthy.
Clean Claim Rate
Target: 95%+Percentage of claims accepted by the payer on first submission without errors or additional information requests.
Every 1% improvement in clean claim rate reduces days in A/R by approximately 1 day and eliminates rework costs.
Days in Accounts Receivable (A/R)
Target: <35 daysAverage number of days between date of service and payment receipt. Measured separately for each payer type.
Every day over 35 represents cash that should be in your bank account. Agencies over 60 days A/R face cash flow crises.
Denial Rate
Target: <5%Percentage of claims denied by the payer (not clearinghouse rejections). Calculated as denied claims divided by total claims submitted.
Each denied claim costs $25-45 in administrative rework. A 10% denial rate on $2M in claims costs $50K-90K annually just in rework.
Collection Rate
Target: 96%+Percentage of billed revenue actually collected. Calculated as payments received divided by total charges billed.
A 96% collection rate on $2M in billings means $1.92M collected. At 90%, you are leaving $120K on the table annually.
Revenue Per Client Per Month
Target: $2,500-$4,500Average monthly revenue generated per active client. Tracks whether your service utilization and pricing are optimal.
Declining revenue per client may indicate reduced hours, rate stagnation, or service mix shift. Track by payer type.
