The deadline for the changeover to ICD-10 is quickly approaching. Your medical office needs to be ready to make the switch to the new code version by Oct.1, 2015.
On that date, the ICD-9 code sets used to report medical diagnoses and inpatient procedures will be replaced by ICD-10 code sets.
The transition to ICD-10 is required for everyone covered by the Health Insurance Portability Accountability Act (HIPAA). The change to ICD-10 does not affect CPT (Current Procedural Terminology) coding for outpatient procedures and physician services.
What is ICD-10?
ICD-10-CM/PCS (International Classification of Diseases, 10th Edition, Clinical Modification /Procedure Coding System) consists of two parts:
First, ICD-10-CM is for diagnosis coding. ICD-10-CM is for use in all U.S. health care settings. Diagnosis coding under ICD-10-CM uses three to seven digits instead of the three to five digits used with ICD-9-CM, but the format of the code sets is similar.
Second, ICD-10-PCS is for inpatient procedure coding. ICD-10-PCS is for use in U.S. inpatient hospital settings only. ICD-10PCS uses seven alphanumeric digits instead of the three or four 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.
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 ICD-9 is 30 years old, has outdated terms, and is inconsistent with current medical practice.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.
Who needs to make the change?
ICD-10 will affect diagnosis and inpatient procedure coding for everyone covered by HIPAA, not just those who submit Medicare or Medicaid claims. The change to ICD-10 does not affect CPT coding for outpatient procedures.
