Invalid diagnosis or procedure codeThe Medicare code Editor checks each diagnosis including the admit-ting diagnosis and each procedure against a table of valid ICD-10-CM and ICD-10-PCS codes. If an entered code does not agree with any code on the internal list, it is assumed to be invalid. For a list of all valid ICD-10-CM and ICD-10-PCS codes, see the International Classification of Diseases External causes of morbidity codes as principal diagnosisExternal causes of morbidity codes are ICD-10-CM codes beginning with the letter V through Y.

5 They describe the circumstance causing an injury, not the nature of the injury, and therefore should not be used as a principal diagnosis. For a list of all external causes of morbidity codes, see the Interna-tional Classification of Diseases Duplicate of PDXW henever a secondary diagnosis is coded the same as the principal diagnosis, the secondary diagnosis is identified as a duplicate of the principal diagnosis. 4.

Age range is 0 17 years inclusive ( , Reye s syn-drome, routine child health exam).
