The ICD-10-CM code sets, which report diagnoses and inpatient procedures, replaced ICD-9-CM in 2015. The transition affects all entities and providers covered by the Health Insurance Portability Accountability Act. ICD-10 -CM coding may be challenging for providers, not the least because the codes are recorded on so many types of health records and are a key component in payment, quality, utilization review, and other data management activities.
ICD-10-CM codes are updated annually, and the current year’s codes are to be used for discharges and patient encounters occurring from October 1 of the current year through September 30 of the following year. CMS’ ICD-10 webpage links to ICD-10-CM codes for current and previous years.
