Why ICD-10?

There were four main reasons that the federal government moved to ICD-10 as a code set standard: (1) ICD-9 dates to 1979 and its functionality has been “exhausted” and does not reflect “new and changing medical advancements”; (2) Parts of the ICD-9-CM were full, which required putting codes in “topically unrelated chapters,” burdensome for healthcare providers in a move toward more efficiency; (3) Insufficient detail opportunities: “[I]n an age of electronic health records, it does not make sense to use a coding system that lacks specificity and does not lend itself well to updates…Emerging health care technologies, new and advanced terminologies, and the need for interoperability amid the increase in…


Classification Coding Systems

ICD-10 diagnosis and procedure codes are “classification coding systems” useful for conducting administrative transactions. SNOMED-CT® (Systematized Nomenclature of Medicine–Clinical Terms) is a “clinically complex terminology standard” designed for the primary documentation of clinical care that will enhance interoperability with electronic health record (EHR) systems. According to the preamble of the proposed ICD-10 rule published on August 22, 2008, “The benefits of using SNOMED-CT® increase if it is linked to a classification system such as ICD-10-CM and ICD-10-PCS for the purpose of generating health information that is necessary for statistical analysis and reimbursement. The use of both SNOMED-CT® and ICD-10-CM and ICD-10-PCS brings value to the development of interoperable electronic health…


Migrating to ICD-10

Under the final ICD-10 rule, all healthcare providers will utilize ICD-10-CM to code diagnoses beginning October 1, 2013. For procedure coding under the final ICD-10 rule, physicians and all healthcare providers other than inpatient hospitals will continue to use the current procedure coding standard: Current Procedural Terminology, 4th Edition (CPT-4) and the Healthcare Common Procedure Coding System (HCPCS). Inpatient hospital services procedures will be coded using ICD-10-PCS codes, which provide facility related procedure codes suitable to inpatient environments.
