Are you located in a state that requires sales tax?

If you are please read the following information:


1. Purpose


This document provides a best practices guideline for reporting taxes on dental services in jurisdictions where applicable. The dental community has come together to provide guidance on use of the CDT Code “D9985 sales tax“ This guideline was proposed by the NADP, and developed in collaboration with the ADA, ASCX12, NDEDIC and WEDI. Individuals from several organizations, acknowledged below, compiled this best practices guideline to instruct the dental community - payers, practice management companies, clearing houses and providers – on how and to apply the code consistently.

2. Background

Recognizing the trend in states adopting sales taxes for health care treatment, the ASC X12,version 5010 electronic claim (837D) allows for the inclusion of sales tax at the line level while the remittance transaction (835) includes provisions for applying such taxes at either the total claim level or at the line level. It was determined that in the absence of having a line level standard available prior to the version 4010/5010 transactions, some dental payers and/or clearinghouses process sales/service taxes in different ways, as indicated below.


 Input a “Dummy” proprietary, procedure code at the claim level or service line level.

 Input a CDT “Not Otherwise Classified” procedure code, for example, D9999 with a written

description/note such as “Sales Tax.”

 Apply the lump-sum sales/service tax at the claim level. To address the inconsistencies, NADP put forth a recommendation through the ADA CDT Code maintenance process to create a new CDT code to support reporting taxes on dental services.

 As of 11/01/2013, three U.S. states have imposed a tax on services rendered: Hawaii, New

Mexico and Minnesota.  More states will be added every year so keep your email open and I will send you any other states as they are added.

CDT Code “D9985 sales tax” is effective January 1, 2014. This code is used in a jurisdiction that has enacted a tax on dental services and the billing dentist or dental entity elects to include this cost on a claim submission.

D9985 can be entered on the service line for each procedure, or in the total where not included in the fee.

The total amount coded to D9985 for each claim, should be the total amount of individual tax amounts for all procedures on the same claim submission.
