Former or current welders or other metal workers frequently have orbit x-rays done prior to a magnetic resonance imaging (MRI) to make sure there are no metal fragments in the eye. What diagnosis code would be assigned for this situation?
According to Coding Clinic, the appropriate diagnosis code would be Z01.89 (encounter for other specified special examinations). When responding to this question, Coding Clinic referenced ICD-10-CM guideline IV.K, which states: “For encounters for routine laboratory/radiology testing in the absence of any signs, symptoms, or associated diagnosis, assign Z01.89, Encounter for other specified special examinations. If routine testing is performed during the same encounter as a test to evaluate a sign, symptom, or diagnosis, it is appropriate to assign both the Z code and the code describing the reason for the non-routine test.”
