HHS proposes one-year delay of ICD-10 compliance date

On April 17, 2012, the Department of Health and Human Services published a proposed rule that would delay from Oct. 1, 2013, to Oct. 1, 2014 the compliance date for the International Classification of Diseases, 10th edition diagnosis and procedure codes (ICD-10).

The ICD-10 compliance date change is part of a proposed rule that would adopt a standard for a unique health plan identifier, adopt a data element that would serve as an other entity identifier and add a national provider identifier requirement. The proposed rule was developed by the Office of e-Health Standards and Services (OESS) as part of its ongoing role, delegated by HHS, to establish standards for electronic health care transactions under the Health Insurance Portability and Accountability Act of 1996. OESS is part of the Centers for Medicare and Medicaid Services.

HHS proposes that covered entities must be in compliance with ICD-10 on Oct. 1, 2014.

A Prerequisite to ICD-10

To prepare for ICD-10, HHS also mandated that transaction standards for all electronic health care claims be upgraded to Version 5010 from Version 4010/4010A standards. Every standard - from claims to eligibility and referral authorizations - was updated to Version 5010 before the enforcement discretion period ended on June 30, 2012.

Why transition to ICD-10?

The transition to ICD-10 is occurring because ICD-9 produces limited data about patients' medical conditions and hospital inpatient procedures. ICD-9 is 30 years old, has outdated terms, and is inconsistent with current and evolving medical practice. Also, the structure of ICD-9 limits the number of new codes that can be created, and many ICD-9 categories are full.

This transition will require business and systems changes throughout the health care industry. To accommodate the ICD-10 code structure, the transaction standards used for electronic health care claims, Version 4010/4010A, must be upgraded to Version 5010 by Jan. 1, 2012.

The change to ICD-10 does not affect CPT coding for outpatient procedures.

What is ICD-10?

The ICD-10-CM/PCS (International Classification of Diseases, 10th Edition, Clinical Modification/Procedure Coding System) consists of two parts ICD-10-CM and ICD-10-PCS.

  • ICD-10-CM is for use in all U.S. health care settings. Diagnosis coding under ICD-10-CM uses 3 to 7 digits instead of the 3 to 5 digits used with ICD-9-CM, but the format of the code sets is similar.
  • ICD-10-PCS is for use in U.S. inpatient hospital settings only. ICD-10-PCS uses 7 alphanumeric digits instead of the 3 or 4 numeric digits used under ICD-9-CM procedure coding. Coding under ICD-10-PCS is much more specific and substantially different from ICD-9-CM procedure coding.

How do I prepare the ICD-10 transition?

It is important to start preparing now for the ICD-10 transition. Here are steps you can take to get started:

KY Medicaid Providers

  • Develop an implementation strategy that includes an assessment of the impact on your organization, a detailed timeline, training, and budget. Check with your billing service, clearinghouse, or practice management software vendor about their compliance plans.
  • Providers who handle billing and software development internally should plan for medical records/coding, clinical, IT, and finance staff to coordinate on ICD-10 transition efforts.

Software vendors, clearinghouses, and billing services

  • Have products and services in development that will allow KY Medicaid providers to fully test and implement ICD-10 code sets prior to October 1, 2015.
  • Talk to your customers now about preparing for the transition. Your products and services will be obsolete if you do not take steps now to get ready.
