ICD-10 0WB34ZX Code Mapping

Terms & Definitions

Alternative: Single ICD-9 code reproduces the complete meaning of one ICD-10 code. Cluster: Multiple ICD-9 codes representing single ICD-10 code. At times it requires multiple ICD-9 codes combined to reproduce the complete meaning of one ICD-10 code. Mapping Types: "Single Code-to-Single Code", "Single Code-to-Cluster", "Cluster-to-Single Code". Note: More than one ICD-9 code (cluster) may be a valid translation of a given ICD-10 code. Which one of those ICD-9 codes (clusters) is the most correct translation must be determined based on the clinical case.
