Counsel for hospitals, post-acute providers, diagnostic facilities, equipment suppliers, rural clinics, PACE organizations, and billing companies.
Not every provider is a physician office, an emergency group, a dental practice, or an infusion pharmacy. Hospitals, post-acute facilities, diagnostic sites, equipment suppliers, rural clinics, PACE organizations, and billing companies each get paid under their own rules. Rivet Health Law advises those providers when a payor applies the wrong rule, or when an audit treats a documentation gap as a recoupment.

The Challenge
A hospital dispute is often a pattern, not one account: a contract rate, an emergency-service payment standard, or an audit sample. Separate a single clinical denial from a department-wide underpayment before you write the letter. Out-of-network emergency payment depends on which statute or contract sets the amount, not on the chargemaster.

Who We Help
The method is the same across settings. Name the benefit and the payment method, then read the record against that method. Joseph Rivet spent more than 20 years in coding, billing, compliance, and reimbursement, including hospital and clinic operations and work on the payer side, before practicing law.
Our Process
These steps organize the file. They are not a substitute for counsel.
Name the provider type and the benefit before you describe the denial.
Pull the letter, the claim, and the payment rule you think the payor ignored.
If several settings are in one organization, keep their claims in separate files.
Calendar the deadline that applies to this provider type, not the one from a different contract.
A critical access hospital is not a small prospective-payment hospital. Medicare inpatient payment is cost-based, and outpatient payment depends on the method the hospital elected. An appeal written in DRG language can miss the actual rule. Commercial plans follow the contract, not the Medicare cost report, unless the contract says otherwise.
Skilled nursing payment follows the days, the assessment, and the skilled need. Notes that repeat the same sentence do not show that need. Assisted living is not a Medicare skilled stay by another name. Long-term care files often contain a short Medicare skilled segment and a longer Medicaid residence. Appeal only the benefit that was actually billed.
Home health coverage generally requires a homebound patient, a skilled need, a practitioner’s care, and a plan of care, supported by a timely face-to-face encounter. Visits that happened are not enough if those elements are missing. Home infusion billed on the home health claim is a separate problem and is covered on the Home Infusion page.
An independent diagnostic testing facility may bill Medicare for the tests it is enrolled to perform, with the supervision those tests require. A new modality or a new site is not covered by last year’s enrollment. Calling the site a physician office on the claim does not change that.
Sleep centers get denied when an attended study is billed without a reason the patient could not complete a home test, or when the order does not match the study. DME suppliers get denied when the order, the coverage criterion in the medical record, and proof of delivery do not agree. The supplier can collect the clinical record. It should not invent it.
A rural health clinic is paid an all-inclusive rate for a qualifying visit, not a fee for every office code. Billing as if the conversion never happened is how the first probe starts. The practitioner who furnished the visit has to be one the rural-health benefit allows.
A PACE organization is paid capitation to furnish the services in the participant’s plan of care. There may be no claim to appeal. Billing companies are not the provider until the services agreement says they may speak for the provider. Answering an audit in the client’s name, or continuing a coding pattern the company knows is unsupported, is its own decision.
