ICD-10-CM Release for 2014 now available

Prior to implementation, the codes in ICD-10-CM are not valid for any purpose or use.

The World Health Organization’s (WHO) International Classification of Diseases (ICD-10) was published in 1992 and is used in over a hundred countries worldwide.

A number of countries have been authorized by WHO to develop “Clinical Modifications” – adaptations of ICD-10 for country specific use. These differ in the number of chapters, codes and subcategories. Specific conditions are present in some adaptations but not all clinical modifications [1]. All modifications to the ICD-10 must conform to WHO conventions for ICD.

Canada uses an adaptation called ICD-10-CA, Australia uses ICD-10-AM, Germany uses ICD-10-GM and Thailand uses ICD-10-TM.

The U.S. lags behind most of the rest of the world and is still using a Clinical Modification of the WHO’s long since retired, ICD-9.

A U.S. specific adaptation of ICD-10 has been under development for a considerable length of time but is scheduled for implementation on October 1, 2014.

Transition to ICD-10-CM is required for everyone covered by the Health Insurance Portability Accountability Act (HIPAA).

Implementation schedules for Large Practices; Small and Medium Practices; Small Hospitals and Payers can be found on the CMS website, here: Implementation Timelines.

2014 release of ICD-10-CM

The 2014 release of ICD-10-CM is now available from the CDC website. It replaces the July 2012 release.

Prior to the implementation date of October 1, 2014, the codes in ICD-10-CM are not valid for any purpose or use.

The ICD-10-CM code set is currently subject to partial code freeze. For information on the code freeze see Partial Freeze of Revisions to ICD-9-CM and ICD-10-CM/PCS.

October 1, 2011 was the last major update of ICD-10-CM/PCS until October 1, 2015. Between October 1, 2011 and October 1, 2015, revisions to ICD-10-CM/PCS will be for new diseases/new technology procedures or minor revisions to correct any reported errors in these classifications. Regular (at least annual) updates to ICD-10-CM/PCS will resume on October 1, 2015.

Information on the ICD-9-CM and ICD-10-CM/PCS update and revision processes and the public NCHS/CDC Coordination and Maintenance Committee meetings can be found on this CDC page: Coordination and Maintenance Committee.

Comparison between classifications and codings in ICD-10-CM and ICD-10

The WHO’s ICD-10 Volume 1 The Tabular List isn’t made available as a PDF file but can be accessed on a searchable electronic browser platform here: ICD-10 Version: 2010.

The Tabular List for ICD-10 contains more textual descriptions for the categories in Chapter V (the mental and behavioural disorders chapter) than other chapters in ICD-10.

There are also two “speciality” volumes for ICD-10 Chapter V for Clinical descriptions and diagnostic guidelines (known as the “Blue Book”) and Diagnostic criteria for research (known as the “Green Book”).

The U.S. specific ICD-10-CM will not contain this depth of textual content within its Chapter 5.

CDC’s, Donna Picket, has confirmed that CMS/CDC does not plan to adapt the “Blue Book” specifically for U.S. use in conjunction with Chapter 5 of ICD-10-CM [2]. Nor are there plans for an official CMS/CDC crosswalk between ICD-10-CM’s Chapter 5 classifications and codes and those in ICD-10 Chapter V [3].

In the U.S., since 2003, the ICD-9-CM diagnostic codes have been mandated for third-party billing and reporting by HIPAA for all electronic transactions for billing and reimbursement. Following implementation on October 1, 2014, the ICD-10-CM codes sets will become mandatory.

This also applies to the coding of mental and behavioural disorders. APA’s DSM-IV disorder diagnoses are crosswalked to ICD-9-CM codes, or their nearest equivalent, for billing and reimbursement.

The DSM-5, published in May this year, includes the crosswalk codes for both the existing ICD-9-CM and the forthcoming ICD-10-CM codes.

For comparison between

ICD-10-CM Chapter 5 Mental, Behavioral and Neurodevelopmental disorders (F01-F99)

and ICD-10 Chapter V Mental and behavioural disorders (F00-F99) see the ICD-10 online browser or
