DME Billing Is a Documentation Business

Durable medical equipment is billed on paperwork more than on product. The item matters far less than whether the record supporting it existed at the right moment.

What must exist before delivery

• A valid order with the required elements, signed and dated by the treating provider.
• A face-to-face encounter where required, within the specified window before the order.
• Medical necessity documentation in the clinical record, not merely on the order.
• Coverage criteria satisfied for the specific item, which frequently means recorded measurements or test results.

The sequence matters as much as the content. Documentation created after delivery does not retroactively make the claim payable, which is what makes DME unlike most billing.

Where suppliers get caught

The referring provider controls the record and the supplier bears the loss. A supplier can deliver in good faith on an order that turns out to lack a required element, and discover it only on post-payment review — at which point the item has been supplied and the payment is recoverable.

The controls

Verify before delivery rather than before billing. Keep a per-item checklist of required elements, because they differ by item. Obtain the clinical record rather than relying on the order alone. And record what you verified and when.

The state layer

Medicaid coverage for DME varies substantially by state — which items are covered, quantity limits, and whether prior authorization applies. A national process will be wrong somewhere, which is why this is one of the specialties where state-level rules genuinely change the work.
