ICD-9-CM to ICD-10-CM Codes: What? Why? How?

Area of Science:

• Medical Informatics
• Health Services Research
• Clinical Coding

Background:

• The wound care industry currently uses the International Classification of Diseases (ICD)-9-Clinical Modification (CM) system.
• The existing system lacks the specificity required to reflect current clinical practice and technological advancements.

Purpose of the Study:

• To outline the benefits of implementing the International Classification of Diseases (ICD)-10-Clinical Modification (CM) for the wound care industry.
• To explain the importance of ICD-10-CM and the transition process from ICD-9-CM.

Main Methods:

• The article describes the features of ICD-9-CM and ICD-10-CM.
• It highlights the increased granularity and specificity of ICD-10-CM codes.
• The transition from ICD-9-CM to ICD-10-CM effective October 1, 2014, is discussed.

Main Results:

• ICD-10-CM offers greater specificity in anatomic sites, etiologies, comorbidities, and complications.
• The new system includes laterality (right, left, bilateral) for improved accuracy.
• Enhanced granularity facilitates better analysis of disease patterns and outbreaks.

Conclusions:

• Implementation of ICD-10-CM will significantly benefit the wound care industry through improved data accuracy and consistency.
• The adoption of ICD-10-CM aligns the United States with international diagnosis coding standards.
• Clinicians and researchers must prepare for the conversion to the more detailed ICD-10-CM system.
