CMS 1500 Box 19: Understanding ‘Reserve for Local Use’ for DME Repair Billing

The CMS 1500 claim form is the standard document used by physicians and suppliers to bill for professional services and supplies. While many fields have explicit instructions, Box 19, labeled “Reserve for Local Use,” offers flexibility that can sometimes cause confusion. This field is designed to accommodate additional information required by specific payers or local Medicare Administrative Contractors (MACs) when no other designated field on the form is appropriate. Understanding its proper application, especially for Durable Medical Equipment (DME) repair billing, is crucial for accurate claim submission guidelines and timely reimbursement.

What Does “Reserve for Local Use” Truly Mean?

On the CMS 1500 form, Box 19 specifies, “Not required unless otherwise noted.” This phrase is key. It means that while the field is typically left blank, certain entities may issue specific requirements for its use. These ‘notes’ or instructions are typically issued by individual payers (private insurance companies), Medicare Administrative Contractors (MACs) for Medicare claims, or state Medicaid programs.

Medical billers and providers must actively look for such payer specific instructions in various official resources. These can include payer bulletins, MAC websites, provider manuals, and state Medicaid handbooks. Staying updated on these guidelines is essential to ensure compliance and avoid claim denials.

CMS 1500 BOX 19 and Durable Medical Equipment (DME) Repairs

One of the most common scenarios where CMS 1500 Box 19 Reserve for Local Use comes into play is with Durable Medical Equipment (DME) repairs. When a DME repair does not require prior authorization, specific detailed information often needs to be communicated to the payer. This information is vital for audit and reimbursement purposes, allowing the payer to understand the necessity and scope of the repair, even without pre-approval.

To ensure proper processing for DME repairs, providers should enter the following details in Box 19, or reference an attachment if space is insufficient:

• The name of the person who requested the repair;
• The date of the request and a specific description of the equipment malfunction;
• A list of procedures and parts used to complete the repair;
• The cost of each procedure and part; and
• The time required to complete the repair.

Hypothetical Example for DME Repair Information in Box 19

Let’s consider a scenario where a patient’s wheelchair requires a repair. If the repair doesn’t need prior authorization, and the payer requires specific details in Box 19, the entry might look something like this:

Example for Box 19: “WCHR Repair: Requested by J. Smith 03/15/2024 for right wheel bearing failure. Replaced bearings (Part# XYZ123, $50), Labor (1.5 hrs @ $75/hr = $112.50). Total cost: $162.50.”

If the information is too extensive for Box 19, you would reference an attachment. For instance, Box 19 might state: “DME Repair Details – See Attached Documentation.” The attachment would then contain all the necessary itemized information.
