Answer: In this case, absolutely. Report the cast application 29065 (Application of cast; shoulder to hand [long arm]). For the E/M service, report a code from the 99281-99285 series (Emergency department visit for the evaluation and management of a patient, which requires three key components ...).
The doctor could not have known the arm needed casting without performing a history, physical exam and an x-ray, so those factors make the visit a legitimately separate E/M service.
