The International Classification of Diseases, 10th Revision (ICD-10) medical coding system is mandated for use by the US Department of Health and Human Services Centers for Medicare and Medicaid Services (CMS). The new codes include enhanced specificity and level of detail, and the transition to the new codes will impact health care providers and trading partners.

The enactment of the Protecting Access to Medicare Act of 2014 included a provision in the statute that ICD-10 will not be adopted as the standard code set until October 1, 2015.  CMS is examining the implications of the provision and will provide guidance soon.

RI Medicaid will continue to provide education and support for preparation and will communicate updates to providers through the monthly Provider Update and this website.  Providers should continue to move forward in their preparation for ICD-10. Updates will be posted as they become available.

To help dispel some of the myths surrounding ICD-10, the Centers for Medicare and Medicaid Services (CMS) recently talked with providers to identify common misperceptions about the transition to ICD-10.  These facts address some of the common questions and concerns CMS has heard about ICD-10.

  1. The ICD-10 transition date is October 1, 2015.  The government, payers, and large providers alike have made a substantial investment in ICD-10.  This cost will rise if the transition is delayed, and further ICD-10 delays will lead to an unnecessary rise in health care costs.  Get ready now for ICD-10.
  2. You don't have to use 68,000 codes.  Your practice does not use all 13,000 diagnosis codes available in ICD-9.  Nor will it be required to use the 68,000 codes that ICD-10 offers.  As you do now, your practice will use a very small subset of the codes.
  3. You will use a similar process to look up ICD-10 codes that you use with ICD-9.  Increasing the number of diagnosis codes does not necessarily make ICD-10 harder to use.  As with ICD-9, an alphabetic index and electronic tools are available to help you with code selection.
  4. Outpatient and office procedure codes aren't changing.  The transition to ICD-10 for diagnosis coding and inpatient procedure codes does not affect the use of CPT for outpatient and office coding.  Your practice will continue to use CPT.

Provider and Vendor Readiness Information

Providers should:
  • Assess staff training needs for the ICD-10 transition.
  • Understand the ICD-10 code sets and begin developing a plan for how your facility will utilize the new codes.
  • Review frequently used ICD-9 codes and crosswalk to ICD-10 codes.
  • Use the resources on the website and visit often to check for updates.

ICD-10 Code Information

Diagnosis coding is based on the documentation in the medical file for each client.  Providers must ensure that the documentation in the record is sufficiently detailed to determine the most accurate diagnosis code that represents the client's condition.  Information about ICD-10-CM (Clinical Modification) and ICD-10-PCS (Procedure Coding System) is available on the CMS ICD-10 website.


RI Medicaid is unable to provide a crosswalk for converting ICD-9 to ICD-10 codes.  Crosswalks are not a substitute for fully implementing ICD-10.  Providers may find the CMS General Equivalence Mappings (GEMs) a helpful tool, but GEMs are not an exact crosswalk between ICD-9 and ICD-10.  Current ICD-9 codes often lack the level of specificity required to determine the correct ICD-10 code so the match may not be accurate.  GEMs are not intended to replace coding based on the client's condition.

ICD-10 Teleconference Training

HP and RI Medicaid conducted training sessions on ICD-10 in March and April. The training offered providers and vendors information and guidance to help prepare for implementation.

Provider and Vendor Communications

ICD-10 updates are included in our monthly Provider Update. Broadcast emails are also sent to the distribution list. In some cases, provider specific emails will be sent to Medicaid providers who provide a specific service.

Provider Resources

RI Medicaid will provide links to valuable resources that support providers in the transition to ICD-10.

Claims and Claims Processing

This section highlights changes to claims and claims processing related to the ICD-10 transition.

Provider Electronic Solutions (PES) Software

The PES software has been modified to accommodate ICD-10 codes and now contains a qualifier to indicate if an ICD-9 or ICD-10 code is being submitted. 

ICD-10 Testing

A testing schedule is being developed for April. If you are interested in testing, please contact your provider representative.
