ICD-10 Schedules and Time frames

Q. What is the time frame for implementing ICD-10?

A. The Family and Social Services Administration (FSSA) and HP Enterprise Services (HP) have completed initial assessments of the Medicaid Management Information System (MMIS) and are now on target for the October 1, 2013, implementation of the ICD-10 code sets.

Q. Will there be regular meetings for stakeholders?

A. The FSSA ICD-10 team is presenting information about ICD-10 at association meetings and meetings with managed care entities. The HP ICD-10 team and HP Provider Relations Field Consultants are also presenting updates at association meetings, provider workshops, and seminars.

Q. Is there going to be a freeze in claims processing?

A. For providers or any system processors, there will not be a freeze on claims processing, enrollment of providers, eligibility, or the Help Desk.

However, there will be a freeze on updating the ICD codes as of October 1, 2012--see the link to the CMS article about the Partial Code Freeze Prior to ICD-10 Implementation on the ICD-10 Information page.

ICD-10 Impact, Assessment, and Benefits

Q. How is using the ICD-10 code sets going to help control healthcare costs and improve patient care?

A. An accounting of the cost control and improvements to patient care and claims processing is outlined in the news release from the U.S. Department of Health and Human Services office titled, HHS Issues Final ICD-10 Code Sets and Updated Electronic Transaction Standards Rules, that is available from the HHS website at hhs.gov.

Here is an assessment of ICD-10's projected impact from an April 2011 CMS ICD-10 Regional Office Training Workshop to help state Medicaid agencies with ICD-10 implementation:

"State Medicaid agencies can pay more accurately based on the greater specificity and granularity of ICD-10 codes… Fine tuning case management and disease management... the increased granularity of codes results in substantially more parameters of diagnosis codes that provide much greater insights into characteristics of patients' health state."

Q. Do providers of Medicaid Waiver (only) services need to be concerned about ICD-10?

A. All providers that use International Classification of Diseases, Ninth Revision (ICD-9) codes need to be aware of, and comply with, the requirement to migrate from ICD-9 to the International Classifications of Disease, Tenth Revision (ICD-10), on October 1, 2013. Providers of Medicaid Waiver services will need to stay informed regarding program requirements associated with the use of the ICD code set.

Q. What opportunities does the change to ICD-10 provide?

A. The top 10 opportunities in the change from ICD-9 to ICD-10 are:

  1. Greater congruence with technological advances in healthcare
  2. Improved care and disease management
  3. Enhanced quality measures
  4. Enhanced medical policies
  5. Improved claims payment accuracy and efficiency
  6. Greater granularity in severity and risk definitions
  7. Enhanced clinical information integration
  8. Greater forward flexibility--ICD-10's alphanumeric format allows for future revision of codes without disrupting the numbering system
  9. More detailed medical concepts
  10. Enhanced code specificity

Q. Who is affected by ICD-10?

A. All providers and vendors that use ICD-9 codes need to comply with the requirement to transition from ICD-9 to ICD-10, effective October 1, 2013.Those billing for Medicaid services need to stay informed regarding program requirements associated with using the ICD-10 code set.

Q. Everything I read states we should be getting ready for ICD-10.  Where do I start?

A. Begin by accessing the ICD-10 Training page on this site for links to the CMS ICD-10 Implementation Handbooks and the ICD-10 and Version 5010 Compliance Timelines Widgets. These publications are free and provide detailed guidance for assessment and planning for ICD-10.

Q. What should we be doing about our computer systems?

A. Review your file layouts and where your files are stored to be sure the fields and your system can accommodate the additional code length. Contact your software vendor to resolve concerns. Here are other ways to prepare:

  • Familiarize yourself with the ICD-10 code set and coding guidelines to help assess the impact on your system.
  • Note that the CMS-1500 form is in revision, and the diagnosis codes are expanding from four to 12 entries. Watch for information about the new release of this form.
  • Do not stop assessment and planning while awaiting the final decision by CMS about implementation.

ICD-10 Testing

Q. Will there be vendor testing?

A. Vendor testing is scheduled to begin January 1, 2013.

Q. When will test plans for the managed care entities (MCEs) and vendors be available?

A. MCE and vendor test plans will be available in second-quarter 2012.

ICD-10 Prior Authorization

Q. How is prior authorization (PA) affected by ICD-10 and the October 1, 2013, implementation date?

A. Providers will be able to submit ICD-10 PAs beginning in July 2013, which will allow providers to submit ICD-10 diagnosis codes on the PAs when the REQUEST FROM date is on or after October 1, 2013. Providers must split paper PA requests between those with ICD-9 codes and those with ICD-10 codes.

The PA Request Form will undergo some changes and will be available in time for the PA implementation date. The new form will include a version indicator. Complete information about the effective dates, the form, and any other information pertinent to PA and ICD-10 will be communicated before implementation via a bulletin.

Q. Will we be able to submit a PA for a service that is on or after October 1, 2013, before October 1, 2013?

A. Yes. PA for a REQUEST FROM date on or after October 1, 2013, may be submitted on or after July 1, 2013. Information about the PA Request Form and how to submit the form will be published in a bulletin before implementation.

Q. Can a paper PA request contain a REQUEST FROM date before October 1, 2013, and after October 1, 2013, on the same form?

A. No. Paper requests for PAs with REQUEST FROM dates before October 1, 2013 (with ICD-9 codes), must be on separate PA Request Forms than those with REQUEST FROM dates on or after October 1, 2013 (with ICD-10 codes).

ICD-10 CODES and Claims

Q. Why are we proceeding before the final versions of claim forms are available? Do you know when final claim forms will be available?

A. Due to the scope of the transition from ICD-9 to ICD-10, if entities expect to be compliant by October 1, 2013 (as mandated by CMS), they must proceed with planning, development, and implementation before updated versions of claim forms are final. With respect to paper claim forms, the IHCP will keep an eye on developments and notify providers when the updated versions become available.

Q. Will providers and vendors be able to use International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes after the October 1, 2013, implementation of ICD-10?

A. You must use ICD-10 codes for dates of service (DOS) or dates of discharge (DOD) on or after the October 1, 2013, implementation date. There is no grace period.

Claims with ICD-9 codes and DOS or DOD before the implementation date will continue to process as they do today.

Q. How are codes being validated on claim submissions in ICD-10?

A. The code specificity validation check is not changing. There will be no up-front validity check for the letters "O" and "I."

Q. Why do the General Equivalence Mappings (GEMs) go in both directions (from ICD-9-CM to ICD-10-PCS, and from ICD-10-PCS back to ICD-9-CM)?

A. The GEMs are designed like a translation dictionary. They go in both directions so you can look up a code to find what it means according to the concepts and structure used by the other coding system, similar to how Spanish-English and English-Spanish dictionaries are designed. Neither the two dictionaries nor the GEMs are mirror images of each other. Because the translation alternatives are based on the meaning of the code you are looking up (which includes index entries, tabular instruction, and applicable Coding Clinic advice), the ICD-10-Procedure Coding System (PCS) to ICD-9-CM GEM is not a mirror image of the ICD-9-CM to ICD-10-PCS GEM.

The GEMs were designed to convert current ICD-9 codes to applicable ICD-10 codes. Starting with an ICD-9-CM code, users can map an ICD-10-PCS code to an ICD-9-CM GEM, and convert payment logic or coverage decisions from ICD-9 codes to ICD-10 codes.

This ICD-10-PCS to ICD-9-CM GEMs mapping can also be used to examine trend data over multiple years, spanning the implementation of ICD-10. For example, in 2013, it will be possible to compare how frequency changed for a specific condition using an ICD-10 code, compared to prior years using an ICD-9 code.

Conversely, mapping an ICD-9-CM code to an ICD-10-PCS GEM can be used to convert ICD-9-based edits, and for any analysis or conversion that needs to examine ICD-10 codes and determine the ICD-9-CM codes that previously captured this diagnosis or procedure.

Bidirectional mapping is required because results may be different based on clinical or terminology differences between the two code sets.

For more information, see the CMS.gov Frequently Asked Questions web page.

Q. Are a list of ICD-10 codes and the crosswalking information for ICD-9 to ICD-10 available?

A. The current list of ICD-10 codes is available for purchase from most online vendors. Some of the codes may be accessed online by searching on "ICD-10 codes."

Crosswalking ICD-9 to ICD-10 codes is addressed in the CMS General Equivalence Mappings (GEMs) publications available on the CMS website. You can find a link to these publications on the ICD-10 Training page.

Consider subscribing to the CMS Email Updates to stay current on what is happening with ICD-10. The sign-up for notifications from CMS is available from the CMS website at cms.gov.

Q. Are there going to be changes to the CMS-1500 claim form as a result of ICD-10? If so, what are the changes, when will the form be published, and when are we expected to use it?

A. The CMS-1500 is currently in revision. Although there is no date for publication at this time, the intent is to have the form available in time to coincide with the implementation of ICD-10.

The form will require a qualifier entry to differentiate between ICD-9 and ICD-10 claims. Another proposed revision to the form is to expand the number of diagnosis entries from four to 12. HP will inform you when the revised CMS-1500 is approved and ready to use.

Q. What about claims that span the October 1, 2013, implementation date?

A. Mixing ICD versions will not be allowed. Any claims that are submitted with mixed ICD versions will be rejected. See the ICD-10 Decisions page for the breakdown of the ICD-10 span date logic by claim type.

Q. Will the implementation of ICD-10 be based on date of service or date of receipt for claims processing?

A. All claims received on or after October 1, 2013, will require a version indicator (ICD-9 = 9 or ICD-10 = 0). Claims with date of service (DOS) on or after October 1, 2013, that require diagnoses will be required to use ICD-10 diagnosis codes.

Q. What claim types require ICD-10 codes?

A. All claim types except dental require ICD-10 codes.

Q. Will Medicaid accept claims with both ICD-10 and ICD-9 codes?

A. Medicaid will accept claims only if ICD-9 and ICD-10 are submitted on separate claims. Claims submitted with both ICD-9 and ICD-10 codes will reject.

Q. Will Medicaid require the use of a decimal point on electronic claim submissions?

A. No decimal point will be required on electronic claim submissions.

Q. Is the IHCP going to publish the new ICD-10 codes that relate to policies?

A. Yes. They will be published in bulletins before ICD-10 implementation.
