Injury of olfactory nerve, right side, subsequent encounter

This code signifies an injury to the right olfactory nerve, which is responsible for the sense of smell. This specific code is used when the patient is receiving follow-up care for the initial injury, such as ongoing treatment, monitoring for complications, or rehabilitation.

Use this code for patients presenting for subsequent treatment of a right-sided olfactory nerve injury, such as for persistent anosmia or hyposmia following trauma, or for evaluation of nerve regeneration. Documentation should clearly indicate the right side of involvement and that the encounter is not for the initial injury.

• Ensure documentation specifies "right side" and "subsequent encounter" to support this code.
• Distinguish from initial encounters (A) and sequela (S) codes for olfactory nerve injuries.
• Code any associated conditions, such as skull fracture, in addition to this code.
