# Your durable medical equipment claims fail on thresholds nobody tracks across the month.

*The rule is a running total. A claim form has nowhere to put one.*

> Durable medical equipment billing is the work of claiming for equipment supplied to a patient for use at home, under rules that decide whether an item is rented or purchased, whether prior authorisation is needed, and what the payer will reimburse. The difficulty is rarely the individual claim. It is that authorisation and reimbursement rules turn on cumulative amounts measured across a month or a rental period, not on the item in front of you.

## What Neurobird Durable Medical Equipment DME Billing does

- Maintain cumulative cost per item group across the period the payer measures, not per claim.
- Flag when an authorisation threshold is about to be crossed rather than after the denial arrives.
- Record rental periods and any rental break requested, so the clock on an item is always visible.
- Hold the authorisation decision and its reasoning against the patient record for later appeal.

## How it works

1. **Set up** Each item is recorded with its group, its rental or purchase designation and the payer rules that apply, because those decide which running total it feeds.
2. **Accumulate** Costs roll up across the period the payer uses, so a repair billed late in the month is assessed against what has already been supplied.
3. **Claim and defend** Authorisation decisions, rental breaks and denials stay attached to the patient, which is what an appeal actually needs.

## Questions

### What is durable medical equipment billing?

It is the process of claiming reimbursement for equipment supplied for a patient's use at home, such as wheelchairs, hospital beds, oxygen equipment and their accessories. Reimbursement may be made for the rental or the purchase of the equipment depending on the item and the payer's designation. The billing work involves establishing medical necessity, obtaining any prior authorisation required, choosing between rental and purchase correctly, and tracking rental periods across months.

### When is prior authorisation required?

It depends on the payer and, importantly, on cumulative amounts rather than single items. California rules exempt wheelchair repairs and maintenance from a treatment authorisation request while cumulative cost remains at or below $2,500 within a calendar month, and apply authorisation to rentals within a group once cumulative cost exceeds $50 across a fifteen month period. Because both are running totals, the answer can change midway through a month.

### What is a rental break?

It is a pause in a rental arrangement, requested by updating an existing approved authorisation rather than starting again. California allows a provider to request a sixty day rental break by updating the existing approved treatment authorisation or service authorisation request. Recording when a break was requested and granted matters, because rental clocks drive later reimbursement.

### Does the payer have to cover the item we supplied?

Not necessarily the one you chose. State regulation can limit authorisation to the lowest cost item that meets the member's need, which means a clinically reasonable upgrade may still be reimbursed at the lower level unless the justification is documented. The documentation is the difference between a covered supply and an absorbed cost.

### Is this available now?

No. It is in development and open for early access. We are building the threshold tracking with billing teams who deal with more than one payer's rules.
