HCPCS codes no longer requiring invoice - Avoid rejected claims

To reduce provider burden, certain contractor-priced HCPCS codes no longer require a paper invoice.

When the invoice information is entered in the narrative field on a claim for any of the HCPCS codes listed below, it is not necessary to provide the actual paper invoice for these services.

The required narrative information includes:

Invoice dollar amount and quantity for the drug or biological.

Name of the drug or biological administered.

The dosage of the medication or the size of the biological administered.

The route of administration if applicable.

Claims not containing information about the invoice or cost associated with the code(s) will reject as unprocessable.

Drug and biological claims or claim lines may be rejected when the submitted documentation does not include both the specific drug name and the actual dose administered to the beneficiary. Submission of the drug name and strength alone, without identification of the administered dosage, is insufficient to support accurate pricing and payment determinations. Accurate allowance calculations require clear documentation of the total units administered, expressed in milligrams, micrograms, milliliters, international units, or other applicable dosage measures, as appropriate for the drug billed. When this information is not provided, the contractor cannot determine the correct payable amount using established pricing methodologies. Claims that do not include complete dosage information may be denied or rejected until sufficient documentation is submitted to support the calculation of the applicable allowance.

Invoice amount

Enter the invoice amount in item 19 of the CMS-1500 paper claim form or the electronic equivalent using the following format (including cents):

Inv. $00.00 for list product name, description/size, quantity per invoice.

Claim example:

The provider administered 6 square centimeters of the biological represented by code Q4176 (Neopatch, or therion, per square centimeter), therefore procedure code Q4176 was billed with a quantity of "6".

The invoice showed $1140.00 for Neopatch Membrane 2cm x 3cm:

When drugs and biologicals are priced based on invoice methodology, the submitted provider cost must reflect the provider’s actual acquisition cost. This includes accounting for any discounts, rebates, prompt-pay reductions, chargebacks, credits, or other price concessions received from manufacturers, distributors, or group purchasing organizations. Invoice pricing determinations will be based on the new acquisition cost after all applicable reductions, not the gross or list price.
