International Classification of Diseases, 10th Edition (ICD-10)

The transition to ICD-10 is necessary due to the data limitations ICD-9 produces related to patients’ conditions and hospital inpatient procedures. ICD-9 is outdated, inconsistent with current medical practice and limits the creation of new codes. ICD-10 provides an expanded set of diagnosis (ICD-10-CM) and procedure (ICD-10-PCS) codes to keep pace with medical and technological advances. In preparation for the full implementation of ICD-10 code sets on October 1, 2015, the Iowa Medicaid Enterprise (IME) encourages all providers to test ICD-10 claim submissions.
