1 Common Hand Surgery Diagnosis Codes ICD-10

Common Hand Surgery Diagnosis Codes ICD-10 This is a list of common codes for diagnoses about the hand and wrist. This is not an exhaustive list of all upper extremity codes. FORMAT of ICD-10: ICD-10 codes have 3-7 digits (varies per code/diagnosis) Format is XXX.XXXX First is letter, second is number, remainder are letter or number; not case-sensitive Some codes require a seventh character but not a fifth or sixth, so a placeholder X is used (example: T84.9xxA) FORMAT OF THIS LIST: For each ICD-10 code, use the list immediately below the code to complete the code ( fill in the blanks ). One must carry each code to the last character listed, unless otherwise stated. The leftmost column lists the similar ICD-9 Code. This is not always a direct translation so read the description and use the correct code. Abbreviations for Fingers: R=right, L=left; 1=thumb, 2=index, 3=long/middle, 4=ring, 5=small/little.
