Medicaid MCO Long-Term Services and Support Providers

An extension to the deadline for LTSS providers serving managed care members (“MCO LTSS providers”) required to enroll through the Medicaid MCO LTSS provider enrollment process has been extended to February 1, 2019.

To allow sufficient time for application processing, MCO LTSS providers are strongly advised to submit applications as soon as possible.  LTSS providers who have not either started or completed the enrollment process and are still billing the MCOs will receive the letter below and should take immediate action in order to meet the February 1, 2019, enrollment deadline.

An MCO LTSS provider is any provider who provides LTSS services under a specific NPI and taxonomy combination and submits claims through Medicaid Managed Care. An MCO LTSS provider will have to enroll through this process when the NPI and taxonomy combination they bill LTSS services with does not have an active, associated TPI through TMHP or an API through this process.

MCO LTSS providers, must complete the enrollment process by the deadline to be able to provide services and submit claims to the MCOs for payment consideration. Please reference the attached the Quick Tips document and the LTSS Taxonomies document.

MCO LTSS providers may obtain an application by submitting a request to The request must include the provider's business name, tax identification number, taxonomy and National Provider Identifier.

MCO LTSS Master Provider File

Effective December 1, 2018, HHSC will resume uploading the LTSS Master Provider File in a text format to a central location, MCODATA folder, on TexMedCentral for all MCOs to retrieve on Mondays. The LTSS Master Provider File will no longer be uploaded to each MCO’s XXXLIB folders. Please refer to the LTSS Master Provider File JIP examples attached in the below LTSS MPF_MCO and HHSC Procedures document. This document gives an overview of the LTSS Master Provider File process:

Ordering- and Referring-only Providers

Due to the impact of Hurricane Harvey, and pending clarification from the Centers for Medicare & Medicaid Services, the Texas Health and Human Services Commission delayed implementing required enrollment of all ordering, referring or prescribing providers which initially was scheduled to happen in October.

Beginning Jan. 15, 2018, claims for the payment of items and services ordered, referred or prescribed must contain the National Provider Identifier of the physician or other professional who ordered, referred or prescribed the items or services. In addition, all ordering, referring or prescribing providers must enroll in Texas Medicaid as participating providers.

These requirements affect Medicaid, Healthy Texas Women and the Children with Special Health Care Needs Services Program only. However, these requirements don’t apply to out-of-network providers who order, refer or prescribe only for managed care members.

HHSC is allowing a three-month grace period from Jan. 15, 2018, to April 16, 2018, during which it will deny claims not meeting these requirements, and then reprocess them to allow providers more time to complete enrollment and minimize client and provider impact.

The Ordering, Referring, and Prescribing Providers Frequently Asked Questions (PDF)document is now available on the TMHP website.

Except for out-of-network providers who order items or services for managed care members, all providers who order, refer or prescribe for clients enrolled in Medicaid, HTW or the CSHCN Services Program should begin the enrollment process immediately by completing the application on the TMHP website.
