A missing record, an incorrect rental sequence, or a denial left unresolved can affect several months on the same account. Meanwhile, the supplier still has equipment costs, service responsibilities, and staff to pay.
Keeping rental revenue on track takes more than generating recurring claims. Each account needs an accurate rental history, current coverage information, and follow-up when payments fall behind.
Below are common DME rental billing mistakes and practical ways to address them.
1. Applying the Same Billing Rules to Every Rental Item
Not all rental equipment follows the same payment structure.
Medicare Part B generally pays for certain capped rental items, such as hospital beds and wheelchairs, for up to 13 months of continuous use. Oxygen equipment has a different payment structure. Other payers may have their own rental limits and requirements.
Problems arise when a billing system uses the same settings across equipment categories. A schedule that works for one item may create incorrect claims for another.
Before setting up recurring billing, confirm the equipment’s payment category, applicable rental limits, and payer requirements. Record those details in the account so staff can check them without starting the research again each month.
2. Losing Track of the Rental History
A delivery date tells you when the equipment reached the patient. It does not explain which rental months have been billed, paid, denied, or left unresolved.
For example, an account may have six submitted claims but only four payments. Unless the billing record separates those statuses, staff may overlook two unpaid months while continuing to submit new claims.
Track these details for each rental account:
- Original delivery date
- Rental periods billed
- Payments received
- Rejected or denied claims
- Pending corrections or appeals
- Relevant history from a previous supplier
A submitted claim should never be treated as a collected payment. Before changing the rental sequence, compare the account history with payer records and the applicable billing rules.
3. Assuming the First Payment Confirms Future Coverage
The first rental payment can make an account appear settled. However, coverage information and account circumstances can change during the rental period.
A patient may switch insurance plans. An authorization may reach its approved limit. Equipment-specific continued coverage requirements may need attention.
If recurring claims run without any review, the billing team may discover the change only after payments stop.
Use account alerts for known authorization limits, coverage changes, and outstanding requirements. Verify information according to payer rules and whenever a relevant change is reported.
When a claim is denied, check whether the issue also affects the next scheduled rental claim.
4. Leaving Documentation Requests Open
A prescription is part of the claim record, but it may not provide everything needed to support payment.
CMS documentation requirements include a standard written order, supporting medical records, and proof of delivery. Certain items require a written order before delivery. Requirements for continued medical need and use must also be addressed where applicable.
The operational problem is often follow-through. Someone requests a document, adds a note, and moves on. Weeks later, the account still says “waiting for records,” with no clear next step.
Every outstanding request should identify:
- The exact document needed
- Who was contacted
- When the request was sent
- Who owns the follow-up
- Whether any claim deadline is approaching
This makes missing records easier to manage and helps prevent the same gap from carrying into later rental months.
5. Restarting the Rental Period After a Billing Interruption
A gap in payments does not automatically mean a new rental period can begin.
CGS distinguishes a break in billing from a break in medical necessity. An interruption in billing without a change in medical need does not, by itself, start a new capped rental period. Whether a new period is allowed depends on the equipment and applicable policy.
Before restarting an account, establish why billing stopped. Was there an insurance change, a facility stay, or an administrative mistake? Did the patient’s need for the equipment end?
Document the reason and review the relevant requirements. Creating a new rental record in the software does not establish that a payer will recognize a new rental period.
6. Letting Equipment Status and Billing Status Drift Apart
Rental billing depends on information from delivery, service, and pickup teams.
If equipment is returned but the account is not updated, recurring claims may continue. If an equipment change is recorded only in a service note, the billing team may miss information it needs to review the account.
CGS guidance states that suppliers must discontinue Medicare billing when rental items are no longer being used by the beneficiary.
Create a clear handoff for returns, pickups, replacements, and reported changes in use. Each update should trigger a billing review.
Before releasing recurring claims, compare the active rental list with equipment status records. Investigate accounts where the two do not match.
7. Allowing One Denial to Affect Several Months
An unresolved denial can become a larger collection problem when the same issue remains on later claims.
For example, if required information is missing from an account, submitting another claim the following month may repeat the problem. The balance grows while staff continue working on the first denial.
When reviewing a denied rental claim, determine whether the cause is limited to that claim or affects the account more broadly.
Identify all affected rental periods, the information needed, and the appropriate correction or appeal process. Assign someone to follow the issue through resolution, with attention to applicable deadlines.
Review related claims before sending them again. Repeated submission without addressing the cause adds work without moving the account forward.
8. Measuring Submission Volume Instead of Collections
A report showing that every scheduled claim was submitted can look reassuring. It still does not tell you whether those claims were accepted or paid correctly.
Rental billing reports should show what happened after submission.
Compare expected payments with actual payments using the applicable fee schedule or payer contract. Investigate missing payments, unexpected adjustments, and differences in reimbursement.
Keep payer balances separate from patient responsibility so follow-up reaches the correct party.
A useful monthly report should help answer three questions: Which rental periods remain unpaid? Why are they outstanding? What action is being taken?
Get Help With Rental Accounts That Keep Falling Behind
When several months remain unpaid on a rental account, review where payments stopped and whether later claims have the same issue. One missing record or unresolved denial may leave multiple months outstanding.
If these reviews keep getting pushed aside, DME billing service providers like OneMed Billing can help review the affected months, follow up on missing records, and track corrections or appeals.
Ask for a report showing each unpaid rental month, what is holding up payment, and the next step. That gives your team a clear way to check progress instead of repeatedly revisiting the same unresolved accounts.
Make Rental Account Reviews Part of the Monthly Routine
Before each billing cycle, review accounts with unpaid prior months, missing documents, coverage changes, or equipment status updates. Give each issue an owner and a follow-up date.
After payments arrive, compare them with the amounts expected and investigate differences.
This routine connects current billing with older unpaid claims. It helps suppliers identify where collections are falling behind while there is still time to take the next appropriate step.
