At scale, DME suppliers run three resupply eligibility checks on every order: active coverage through an electronic 270/271 request, whether the payer’s frequency limit allows another shipment, and a documented patient confirmation that the supplies are needed. Software can automate the first two in bulk. The third still depends on the patient’s answer.
The Three Resupply Eligibility Checks
1. Is coverage still active?
Suppliers send an X12 270 eligibility request and get a 271 response back. For Medicare fee-for-service, that runs through the CMS HIPAA Eligibility Transaction System (HETS). HETS works in real time only and does not accept batch files, so high-volume suppliers need a tool that sends requests one by one. Commercial and Medicare Advantage checks usually go through a clearinghouse or payer portal.
Most of the industry already works this way. The 2024 CAQH Index reports that 96% of medical plan eligibility checks are fully electronic, and estimates that providers save about 12 minutes on each check they move from manual to electronic.
2. Does the frequency limit allow it?
Each payer caps how often an item can be replaced. For PAP supplies, Medicare publishes usual maximums in LCD L33718:
Item | HCPCS | Usual maximum |
Full face mask | A7030 | 1 per 3 months |
Nasal mask cushion | A7032 | 2 per month |
Tubing | A7037 | 1 per 3 months |
Disposable filter | A7038 | 2 per month |
Commercial and Medicare Advantage plans often set their own limits, so the rules have to be stored per payer.
3. Has the patient confirmed the need?
Under the same LCD, suppliers may contact the patient no sooner than 30 days before the current supply runs out, must document an affirmative response, and may deliver no sooner than 10 days before it runs out.
What Software Can and Cannot Do
Suppliers usually combine DME platforms with built-in eligibility and frequency rules, clearinghouses for multi-payer 270/271 checks, and outsourced resupply services for patient calls. Software can batch-schedule checks, flag patients who are due, and route exceptions to staff. It cannot confirm a patient’s need without the patient’s answer. Staff still handle incomplete 271 responses and mid-year plan switches, which is why suppliers re-check coverage every cycle. See how this plays out across Medicare fee-for-service and Medicare Advantage rules, and how missed checks become claim denials.
Where NikoHealth Fits
NikoHealth verifies commercial and government eligibility before fulfillment and again before claim submission. Its payer rules engine stores frequency guidelines per payer, and NikoHealth Resupply surfaces patients who are due based on order history and those rules.
