Oth fx shaft of right ulna, init for opn fx type I/2

This code signifies a fracture of the shaft of the right ulna, not otherwise specified as a specific type (e.g., Monteggia, Galeazzi), where the skin has been broken, exposing the bone. The "initial encounter" indicates that this code is used for the patient's first visit for this specific injury.

This code is appropriate for documenting an open fracture of the right ulnar shaft, classified as Gustilo type I or II, during the acute phase of treatment. This includes initial evaluation, surgical repair, or casting. It would be used, for example, when a patient presents to the emergency department with a visible wound over a fractured right ulna.

• Ensure documentation clearly specifies "right ulna" and "shaft" to differentiate from other forearm bones or ulnar processes.
• Verify that the open fracture is explicitly documented as Gustilo type I or II; if not specified, query the provider.
• This code is only for the initial encounter; subsequent care would require a different encounter character (e.g., D for subsequent, S for sequela).
