How do I bill Medicaid for home care?
Enroll with your state Medicaid programme and contract with the managed care organisations that control authorizations in your area. Verify member eligibility, obtain prior authorization where required, capture EVV for every visit, and submit claims through a clearinghouse or the state portal. Rules vary substantially by state.
The four checks before a shift is billable
Medicaid claims fail on eligibility, authorization, EVV and coding - usually in that order of frequency. All four have to be true for a delivered hour to convert into revenue.
- The member was eligible on the date of service, and had not lost coverage at redetermination
- A current prior authorization covers the service, the units and the date
- EVV data exists and matches the scheduled and billed visit
- Service codes and modifiers match the payer's specification
Eligibility is a moving target
Members lose coverage at redetermination without telling their care agency, and states are shortening renewal cycles - Virginia moves expansion members to six-month renewals in January 2027, which doubles the number of opportunities for a silent lapse.
Weekly batch eligibility verification is the practical defence. It converts an unrecoverable write-off into a scheduling conversation.
People also ask
- Is Medicaid billing the same in every state?
- No. Programme names, waiver structures, EVV vendors, rates, prior authorization rules and claim submission routes are all set at state level. An agency expanding across a state line is entering a genuinely different billing environment.
- Do I bill the state or the MCO?
- Usually the MCO if the member is in managed care, and the state if they are fee-for-service. Many agencies bill both, with different rules for each.

Related answers
What is EVV and why do my claims fail because of it?
Electronic Visit Verification is the federally required electronic record of who delivered care, to whom, where and when. Claims fail when EVV data disagrees with the billed visit - a missed clock-in, a rounded time, or a visit recorded in one system but billed from another. The payer trusts the EVV record.
What is a Medicaid HCBS waiver?
A Home and Community-Based Services waiver lets a state use Medicaid funds to pay for care in someone's home rather than an institution. For a home care agency it is the funding mechanism behind most Medicaid personal care work, and each waiver has its own eligibility criteria, service definitions, rates and authorization rules.
Why do home care claims get denied?
Most home care denials are created before submission, not during adjudication. The recurring causes are an expired or missing authorization, a mismatch between delivered and authorized hours, EVV data that disagrees with the billed visit, coverage that lapsed at redetermination, and wrong service codes or modifiers.
Do I need a Type 2 NPI to bill the VA or Medicaid?
Yes. A Type 2 (organisational) NPI identifies the agency as a billing entity, as opposed to a Type 1 which identifies an individual clinician. You also need your taxonomy in NPPES to reflect the home care services you deliver, because a mismatch there causes denials that surface months later.
How does Medicaid home care billing differ by state?
Almost everything that affects billing is set at state level: the programme and waiver names, which MCOs hold contracts, the EVV vendor and aggregator, service codes and rates, prior authorization rules, and the claim submission route. Crossing a state line means learning a genuinely different billing environment.
What does outsourced home care billing cost?
Outsourced home care billing is usually priced as a percentage of collections, so the cost scales with revenue actually received rather than claims submitted. Compare it against fully loaded in-house cost - salary, benefits, software, training and the revenue lost to denials - not against salary alone.
