A missing KX, an expired CMN, a capped-rental month miscounted, or proof-of-delivery gone astray turns a paid claim into a recoupment. Helix keeps HCPCS, modifiers and documentation airtight so DME claims pay and survive audit.

DME MACs pay on paper as much as on product. The right HCPCS code is worthless without the matching modifier, a current CMN or standard written order, proof of delivery, and a correctly tracked rental schedule — and any gap invites recoupment months later.
Helix builds the documentation trail into the claim: modifier logic tied to coverage criteria, CMN/DIF and POD verification, capped-rental and prior-auth tracking, all aligned to DME MAC and CERT requirements.
KX, GA, GZ, RR/NU/UE applied to match the documentation.
Certificates, written orders and POD verified before billing.
Rental months tracked, conversions and prior auth managed.
DME MAC, CERT and supplier-audit documentation in order.
DME claims live and die on HCPCS-plus-modifier accuracy and the documentation behind them. We keep both aligned on every line.

KX absent when coverage criteria are met, or GA/GZ missing on an expected denial.
Helix fix: modifier logic ties KX/GA/GZ to the documented coverage status.
No current Certificate of Medical Necessity or standard written order to support necessity.
Helix fix: CMN/order verification gate blocks billing until documentation is current.
Rental billed past the capped-rental cap or not converted to purchase on schedule.
Helix fix: rental-month tracker flags caps and triggers purchase conversion.
PA-required item (e.g. power mobility) delivered and billed without authorization on file.
Helix fix: PA workflow secures and attaches authorization before delivery.
Order, coverage criteria and prior auth verified up front.
HCPCS with KX/GA/GZ and RR/NU/UE matched to documentation.
CMN, POD and capped-rental schedule validated pre-submission.
Appeals, recoupment defense and aged-A/R workdown.
"We were getting hammered on modifier and CMN denials and a CERT audit was looming. Helix locked down the documentation and turned our cash flow around."
A multi-location supplier with KX/GA modifier denials, expired CMNs, capped-rental miscounts, and a backlog of recoupments after a documentation lapse.
Helix implemented modifier-to-coverage logic, a CMN/order verification gate, capped-rental and prior-auth tracking, and ran a 90-day appeal and recoupment-defense recovery.
Clean-claim rate reached 98.6%, A/R days fell to 24, the supplier recovered $394K, passed CERT review, and net revenue rose 22%.

"Compliance documentation for CPAP resupply was killing us. Helix tied the modifiers to the records and the denials dropped off."
Result: $163K recovered in year one.
"Power-wheelchair prior auths were a black hole. Helix built a real PA workflow and our approvals finally stuck."
Result: +$29K average monthly net revenue.
