Final answer:
The correct ICD-10-CM codes for the second ED visit are S02.2XXA for the nasal fracture initial encounter and T79.2XXA for the post-traumatic wound bleeding initial encounter. Codes S02.2XXS and S02.2XXD are not applicable as 'S' is for sequela and 'D' is for subsequent encounters for routine healing.
Step-by-step explanation:
For the second emergency department visit for new bleeding from both nares due to a nasal fracture, two ICD-10-CM codes should be reported: One for the nasal fracture and one for the complication of the fracture. The correct codes would be: S02.2XXA for the fracture of nasal bones, initial encounter, since this is a new presentation of active bleeding and requires active treatment; and T79.2XXA for the complication of the fracture, which in this case is the post-traumatic wound bleeding, initial encounter.
Code R04.0 for epistaxis would not be reported as the bleeding is due to a known fracture. The other options, S02.2XXS and S02.2XXD, are incorrect because the seventh character 'S' is for sequela (complications or conditions that arise as a direct result of a condition), and 'D' is for subsequent encounters for fractures with routine healing, which do not apply to this case.
