Final answer:
The coding for a pseudoaneurysm due to cardiac catheterization would be according to ICD guidelines, reflecting a vascular system complication from an iatrogenic cause.
Step-by-step explanation:
The coding for a pseudoaneurysm that developed due to cardiac catheterization in the common femoral artery would be based on ICD (International Classification of Diseases) guidelines. While ICD codes are not provided in the question, the scenario described indicates there was a complication due to a medical procedure. Typically, the coding would reflect a complication related to the vascular system due to an iatrogenic cause (caused by the medical examination or treatment). In the ICD-10-CM code set, which is the relevant coding system for such complications, there would be specific codes for such an incident, and coders would be required to reference the latest coding manual or electronic coding resource to ensure accurate coding.
