If a patient had a hip fracture and had a hip arthroplasty for the fracture repair. The patient is now doing aftercare. Would you code the Hip fracture using the 7th digit for subsequent encounter for routing healing of closed fracture. Or would you use the Zcode for the aftercare of the joint replacement.
In ICD 9 there was a rule that you could not use the aftercare code for a fracture and had to use the aftercare for a joint replacement when the patient had undergone a replacement.

thanks
