Skip to content Credex Healthcare offers DME billing services for home medical equipment suppliers, hospital DME departments, orthotics and prosthetics providers, and respiratory therapy companies that are tired of prior authorization denials, HCPCS code rejections, and Medicare competitive bidding compliance problems eating into monthly collections. DME insurance billing is one of the most documentation-heavy claim types in healthcare. Our DME billing specialists manage that paperwork trail on every order.
Credex Healthcare’s DME revenue cycle management handles the full cycle from order verification and CMN management through claim submission, denial appeals, and payment reconciliation.

CMN & prior authorization management
Credex Healthcare runs a dedicated DME billing process that reviews each order for CMN completeness, verifies that the HCPCS code matches the product’s detailed product description, confirms the ordering physician has a valid NPI and ordering privileges, and checks prior authorization status before the claim is filed. DME billing errors and fixes cost suppliers significant revenue on both ends: denied claims mean delayed payment, and audit recoupments on claims that should never have been submitted mean recovered income. Our team catches both types of problems before they happen.
Our DME billing services in the USA cover the following:
We handle the registration of DME suppliers with Medicare DMEPOS, Medicaid fee-for-service, and managed care programs, as well as private users. This includes ensuring that Medicare supplier numbers are valid and that safety bonds are maintained.
Within 48 hours, denied DME claims are looked at again. If the claim was turned down because of a missing CMN, an incorrect modifier, a prior-authorization gap, or a competitive bidding area conflict, our team fixes it and resubmits it with the necessary paperwork the payer requires.
Our trained coders check product orders against HCPCS codes E0601, A7030, L4361, and K0001, as well as the full DMEPOS code set. They also ensure that modifiers KX, GA, GZ, and RR are used properly based on the order paperwork and whether the item is rented or bought.
Some expensive DMEPOS items, such as power mobility devices and certain orthoses, need to be approved ahead of time by Medicare. Before equipment is submitted, we monitor and prepare authorizations so that no expensive item is sent without approval on file.
The full range of RCM services includes verifying orders, tracking CMNs, entering charges, managing rental cycles, processing payments, and furnishing monthly reports. This way, DME providers can get accurate collection data by product type and customer every billing cycle.
As a US-based DME billing company, Credex Healthcare keeps up with changes to the Medicare DMEPOS competitive bidding program rules by contract area, the Medicaid DME coverage rules by state, and the current prior authorization requirements for oxygen equipment, power mobility devices, and complex rehab technology. For DME equipment to be covered by Medicare, it must align with a National Coverage Determination, come from a supplier in the appropriate competitive bidding area, and be supported by documentation that meets the local coverage determination for that product category. If you get any of those wrong, the claim will not pay out.
Medicare Part B pays for permanent medical equipment when a doctor requests it and other proof shows that it is medically necessary. For every claim, we ensure that the correct HCPCS codes, modifiers, and competitive bidding rules are used by managing Medicare DME bills across all MAC regions.
Coverage for Medicaid DME and the need for prior permission vary from state to state. In some places, you need a PA to procure standard equipment covered by Medicare. Our team stays current with Medicaid DME billing rules in each state and applies them to all claims.
It is harder to bill for power wheelchairs, custom seating systems, and complex rehab technology because they need more paperwork, face-to-face exams, and PA rules than regular DMEPOS billing. The people who work on our DME bills process CRT claims separately from normal equipment claims.
We handle supplier-level PTAN management, location-specific customer enrollments, and combined billing across all sites for DME companies with multiple delivery locations or retail shops. This is done under a single process with unified reports.
DME claims are denied for specific, traceable reasons: missing CMNs, incorrect modifiers, prior authorization gaps, and issues in registering the physician’s NPI. Most of those are preventable. Credex Healthcare checks all of it before a claim is submitted.
Every DME claim is verified against your active Medicare PTAN, supplier NPI, and DMEPOS accreditation status. A lapsed accreditation or mismatched billing NPI is among the fastest ways to trigger an immediate claim rejection or supplier audit.
We verify HCPCS codes across the full DMEPOS range, including E0601 (CPAP device), A7030 (full-face mask), L4361 (ankle-foot orthosis), and K0001 (standard wheelchair). Modifiers KX (medical necessity documented), GA (ABN-issued), GZ (item not covered), RR (rental), and NU (new purchase) are applied based on the actual order documentation.
CMN & Order Documentation Review
Certificates of Medical Necessity are reviewed for completeness, ordering physician signature, and compliance with the product's LCD before charge entry. Incomplete CMNs are flagged back to the supplier before the equipment ships.
Prior Authorization Tracking
Prior authorization for DME equipment is tracked by product category and payer. For Medicare PA-required items, including certain power mobility devices and lower-limb prostheses, authorization is obtained and documented before dispensing. Expired authorizations are renewed before reordering cycles.
Rental vs Purchase Pathway Management
Capped rental equipment, rent-to-purchase items, and outright purchase products each follow different HCPCS modifiers and billing frequency rules. Our team manages the rental cycle calendar, applies the correct modifier at each billing interval, and transitions to purchase coding at the right month.
Accounts Receivable Follow-Up
DME AR is reviewed weekly. Unpaid claims are pursued before the timely filing limits close. Underpayments are checked against the Medicare DMEPOS fee schedule or Medicaid rate, and competitive bidding pricing conflicts are escalated with supporting documentation.
DME suppliers lose revenue in predictable monthly patterns because the billing workflow fails to catch problems before the equipment ships. Power chair claims were denied because the face-to-face exam note did not document the specific mobility limitations Medicare requires. CPAP resupply claims were rejected because the compliance download was not attached. Orthotic claims were paid at the wrong rate because the modifier flagged the item as non-covered when the CMN supported coverage. Credex Healthcare’s DME billing process builds the documentation check into the order intake stage, not the denial follow-up stage.
End-to-end DME insurance billing from order verification and charge entry through HCPCS code assignment and electronic submission to Medicare, Medicaid, and commercial payers across all equipment categories.
Our DME billing specialists apply the correct durable medical equipment billing codes and modifiers for every product type and billing pathway, reducing denials caused by errors in DME documentation requirements.
Prior Authorization Management
Prior authorization for DME equipment is obtained before high-cost items are dispensed. The authorization number is documented and attached to the claim at submission. No power mobility device or complex orthosis ships without a PA on file.
Denial management for DME claims covers CMN deficiency corrections, medical-necessity appeals, competitive-bidding area conflicts, and modifier disputes. Each appeal is built around the specific documentation required by MAC or the payer.
Provider application management covers DMEPOS accreditation verification, Medicare supplier number maintenance, Medicaid enrollment, and commercial payer credentialing, so your supplier number stays active, and billing does not stall at renewal.
Monthly reports cover collections by product category and payer, rental cycle revenue tracking, denial trends by reason code, DME claim reimbursement timelines by carrier, and AR aging, so management sees the full financial picture.

Owner
Ron
“We were getting denied about 30% of our power wheelchair claims, and most of them came back as insufficient medical necessity documentation. Credex audited six months of denials and found that our referral sources were sending face-to-face notes that did not document the functional mobility limitations Medicare actually requires. They gave us a checklist to send back to the physicians, the denial rate dropped to under 6%, and we recovered most of the backlog through appeals. That was a serious amount of money.”
DMD
Susak
“O&P billing is complicated, and most billing companies do not know the difference between an AFO and a KAFO from a documentation standpoint. Credex does. They know which modifiers go on which L-codes, what the LCD requires for each orthotic category, and when a KX modifier is appropriate versus when a GZ will trigger a denial. Our first-pass rate went from 71% to 93%, and we have not had a competitive bidding conflict in months.”
Revenue Cycle Director
Santos
“CPAP and oxygen billing has its own compliance requirements around compliance downloads, resupply authorization, and 90-day rental transitions. The team we had before could not keep track of the rental cycles, and we were consistently billing at the wrong stage. Credex sets up a rental cycle calendar for our full patient census, and the billing errors basically stopped. Our monthly collections went up, and the audit risk went down at the same time.”
CFO
Jerome
“Five locations, three product lines, and two Medicare jurisdictions. Before Credex, we had no consolidated view of what each location was actually collecting versus what it should be collecting. Credex built us a monthly report that breaks down collections, write-offs, and denial rates by site and by product category. We found out one location had been using the wrong competitive bidding pricing for nine months. That alone justified the whole engagement.”
Operations Manager
Linda
“CRT billing has documentation requirements that most DME billers are not trained in. Seating evaluation reports, functional mobility assessments, ATP credentials, all of it must be right, or the claim does not pay. Credex had people who already knew the CRT billing requirements before we signed on. No learning curve, no trial and error with our claims. The transition was clean, and our collections held steady from month one.”
Supplier Assessment
We audit your current billing workflow, product mix, AR aging by payer and equipment category, denial history by reason code, CMN tracking process, and competitive bidding area compliance. This shows where collections are falling short and which problems should be addressed first.
Credentialing & Payer Enrollment
We verify your DMEPOS accreditation status, Medicare PTAN, Medicaid supplier enrollment, and commercial payer credentialing. Any gaps in provider application management are resolved before new claims are submitted.
CMN & Authorization Setup
We review your current CMN workflow, identify product categories that require prior authorization, and build a tracking process to ensure that no high-cost items are dispensed without both a completed CMN and payer authorization on file.
Clean Claim Submission
Our DME billing specialists verify HCPCS codes, modifiers, rental cycle stage, and documentation completeness before submitting claims electronically to Medicare, Medicaid, and commercial payers for every order in the billing queue.
Denial Management & Follow-Up
Every claim is tracked through adjudication. Denials are reviewed within 48 hours. CMN deficiency corrections, modifier disputes, and medical necessity appeals each get a targeted response tailored to the documentation specific to the MAC or payer requirements.
Reporting & Ongoing Optimization
Monthly reports cover collections by product and payer, rental cycle revenue, denial trends by reason code, DME billing turnaround time, and AR aging. Recurring billing errors are addressed at the order intake level, so the same problem does not carry into the next cycle.
DME billing is unlike any other billing specialty. Rental cycle management, CMN tracking, competitive bidding compliance, DMEPOS accreditation requirements, and prior authorization rules for specific product categories all run simultaneously across a supplier’s patient census. General billing companies handle this poorly because the rules are too product-specific to manage a standard outpatient billing workflow. Credex Healthcare focuses on DME revenue cycle management because this specialty requires billing specialists who extensively understand the DMEPOS system and a supplier’s own compliance team.
Our team works on DME claims daily. We know how Medicare's DMEPOS competitive bidding program affects claim pricing by geographic area, how rental-to-purchase transitions work under capped rental rules, how CMN requirements differ by product LCD, and where DME billing errors recur most often. DME billing is not adapted from a physician or outpatient billing workflow here.
Your company works with one dedicated DME billing specialist who knows your product mix, payer contracts, accreditation status, and claim history. Issues are handled by a dedicated expert who already understands your inventory and billing patterns.
Suppliers see collections by product category and payer, rental-cycle revenue tracking, denial trends by reason code, competitive bidding compliance status, and DME billing turnaround time in monthly reports that reflect the business’s actual financial position.
Patient prescription records, CMNs, and medical necessity documentation handled during the billing process are protected under full HIPAA compliance protocols. Documented security controls and strict access management are maintained across all systems used to process your claims.
DME sellers lose money in ways that don’t show up for months. Once the power chairs were delivered, they were turned down because the face-to-face note did not match the LCD. The compliance download was never pulled, so CPAP refill claims remain unpaid. The wrong rate was used for competitive bids because the fee plan wasn’t updated when the contract area changed. That’s what an investigation finds in the first few weeks.
Credex Healthcare starts with a free review of your current DME billing: AR aging by product and payer, denial history by reason code, CMN tracking process, accreditation compliance, and prior authorization gaps. No commitment is needed to get that review. We identify the recoverable revenue and the specific workflow changes that stop the same problems from recurring next quarter.
The DME payment process is how Medicare, Medicaid, and private insurers pay for the durable medical equipment DMEPOS providers offer to patients. Each piece of technology is assigned an HCPCS Level II code, linked to a doctor’s order and a Certificate of Medical Necessity, and submitted with the appropriate modifiers and proof of prior permission.
HCPCS Level II codes are used for DME billing and are grouped by product type. Most CPAP machines for people with obstructive sleep apnea have the code E0601. You can use the A7030 with either CPAP or BiPAP to link to a full-face mask. L4361 is a ready-made orthosis for the ankle and foot. This is a normal motorized wheelchair, K0001.
Part B of Medicare covers DME that is medically necessary, recommended by a doctor, and provided by a DMEPOS seller that is registered with Medicare. Coverage is decided by National Coverage Determinations and Local Coverage Determinations. These specify which evaluations and paperwork are needed for each product. Most business health plans cover DME, but there are different co-insurance, fees, and permission needs.
When all the paperwork is in order, and the right HCPCS codes and modifiers are sent in, Medicare handles clean electronic DME claims in 14 to 30 days. Commercial buyers usually pay for standard equipment within 30 days, provided they have a prior authorization on file. Medicaid DME timelines vary by state and range from 30 to 60 days. All of those are monitored by Credex Healthcare’s pre-submission review before the claim is sent in. This makes sure that most DME claims are processed within the normal DME billing timeframe.
