The first invoice may arrive after a week when you have barely slept. It may show a total due without showing enough detail to tell you how that total was built.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
Do not begin with the total. Put three records beside one another: the signed service agreement, the agency's record of the work, and the invoice. You are looking for whether the same visit appears the same way on all three.
This is separate from the hospice benefit. Medicare pays the hospice for covered hospice services included in the plan of care. Private caregivers may be doing additional work that your family arranged and agreed to pay for. The distinction matters because a private care invoice should not quietly become a bill for something the hospice was supposed to provide or arrange. The federal rules and Medicare materials behind that distinction are collected on the Sources page.
Start with the document that created the charge
Find the agreement that was in effect when the work occurred. Use the signed copy, including every rate sheet, service plan, amendment and attachment. A proposal or intake email may help explain what you expected, but it may not contain the terms the agency used for billing.
What it costs: The Missouri median for non-medical in-home care is $33 an hour, per the CareScout (Genworth) Cost of Care Survey 2025 state data tables, released March 2026. New Plan Care's standard rate is $34 an hour with a four-hour minimum, so a visit starts at $136 (newplancare.com/services).
Mark the provisions for the regular hourly rate, minimum visit length, overnight rate, weekend or holiday rate, transportation, mileage, cancellations, late changes, deposits and administrative fees. Also mark any clause that allows the agency to change a rate. Check what notice the contract says you should receive before a change takes effect.
If a term points to another page, find that page. If the agreement refers to a fee schedule you were never given, ask for the version that applied to the invoiced work. Do not try to reconstruct it from memory.
Rebuild one line at a time
Make a short table on paper. Give each visit its own row. Record the caregiver's name, arrival time, departure time, billed quantity, rate, extra fee and line total. Then copy the corresponding information from the visit record.
Ask the agency what record establishes arrival and departure. It may use a paper sheet, an electronic check-in, a telephone system or a supervisor's correction. You do not need to decide which system is best. You need to know which record controls the bill and how a correction is shown.
Check the arithmetic, but also check the billing unit. A visit lasting part of an hour may be rounded, billed to a minimum or treated as a full shift under the agreement. Ask the agency to point to the exact contract language it used. A correct multiplication can still rest on the wrong number of billable hours.
For an overnight entry, check whether the contract describes awake care, sleeping presence or another defined service. Compare that description with the rate used on the invoice. You are checking paperwork, not deciding what level of care your parent needs.
Separate worked time from contract charges
Some charges do not represent time spent in the house. Put cancellation fees, short-notice fees, mileage, transportation, meals, supplies and deposits in a separate group. For each one, ask four questions:
What event triggered the charge? Where is that event recorded? Which contract paragraph authorizes the charge? How was the amount calculated?
A cancellation entry should identify the scheduled visit and when the cancellation was received. A mileage entry should say whose travel is being billed and how the distance was determined. A deposit credit should be visible somewhere, even if the contract says it will be applied later.
If a caregiver bought household items, compare the reimbursement with the receipt and the agreement's rule for purchases. Keep that separate from the charge for the caregiver's time.
Check who approved changes
A tired family can make several reasonable changes by telephone: stay later, come earlier, add a morning or send a second person. The invoice may be the first place where all of those decisions appear together.
For every changed visit, write down who requested it, who approved it and what rate was stated. Then check the contract for the people allowed to authorize added work. If the agency accepted instructions from a relative who was not listed, ask the agency to explain how it treated that request as authorization.
Do the same when the agency made the change. If a replacement arrived early, stayed beyond the requested time or brought a second worker, ask whether the family approved the billable change. Keep the question narrow: who authorized this charge, and where is that authorization recorded?
Do not use the hospice log as a private care invoice
The hospice record and the private caregiver's record have different jobs. The hospice plan of care identifies hospice services. The private care agreement governs the help you purchased separately. A hospice nurse's visit does not prove that a private caregiver worked a billed shift, and a private caregiver's note does not change what the hospice plan says it will provide.
If the private invoice includes work that sounds like hospice nursing, aide, equipment or supply service, call the hospice before assuming the family owes it. Ask whether the item or service was in the hospice plan of care, whether the hospice arranged it, and whether the hospice considers it related to the terminal illness and related conditions. Medicare tells families to contact the hospice before obtaining care for those conditions from another provider because unarranged care may leave the beneficiary responsible for the cost.
Keep that hospice coverage question separate from a dispute about whether the private agency followed its own contract.
Send one written discrepancy list
When something does not match, send the billing office a short written list. Identify the invoice, the disputed line, the contract provision you are using and the correction you are requesting. Attach copies rather than giving away your originals.
Ask the agency to answer in writing and to provide a corrected invoice or a written explanation. Also ask whether the contract requires payment of the undisputed portion while a line is reviewed. This is a question about the agency's process, not a recommendation to hold back payment.
Keep the names of the people you speak with and a brief note of what they say. If the answer changes, ask which answer the agency will stand behind.
Fix the record before the next invoice
An invoice problem often exposes a record problem in the house. Choose one place for the current agreement, amendments, visit records, invoices and payment confirmations. Give one family member the job of filing changes. That person does not have to manage the care. The job is simply to keep the paper trail complete.
Ask the agency for an itemized invoice format if the first bill was only a summary. Ask how quickly the family can see time records and how corrections are made. Confirm the name and contact information for billing questions. If several relatives may request changes, decide which one is authorized to add billable work and tell the agency in writing.
If the disagreement concerns a hospice rather than a private care bill, Missouri maintains a route for questions and complaints about licensed home health agencies and hospices. The starting points are listed in Local Help for Hospice Families.
You do not have to settle every care question while reviewing an invoice. For this task, stay with the paper. What did the agreement permit? What does the work record show? What did the agency bill? When those three answers match, you can pay knowing what you bought. When they do not, you have a precise question to put in front of the agency before the next bill arrives.
