How coders use this code
ICD-10-CM R84.3 is a billable, fully specified code, so it can be reported directly on a claim to document a diagnosis of abnormal level of substances chiefly nonmedicinal as to source in specimens from respiratory organs and thorax. Coders assign it when the chart documentation supports this level of detail, always matching to the most specific code available and verifying against the chapter-specific guidelines published annually by NCHS/CMS.
