Injury of facial nerve, right side, subsequent encounter

This code signifies a documented injury to the facial nerve on the right side, occurring during a subsequent encounter for care. This typically involves damage to the seventh cranial nerve, which controls facial expressions, taste sensation, and tear/salivary gland function. The "subsequent encounter" indicates the patient is receiving routine care during the healing or recovery phase of the injury.

Use this code when a patient presents for follow-up care, such as wound checks, medication adjustments, physical therapy, or monitoring of nerve recovery, after an initial injury to the right facial nerve. Documentation should clearly state "subsequent encounter" or similar language indicating ongoing treatment for the initial injury. This code is appropriate for conditions like Bell's palsy if a traumatic injury is the underlying cause, or post-surgical nerve damage.

• Ensure documentation specifies "right side" and "subsequent encounter" to support this specific code.
• Distinguish between initial (A), subsequent (D), and sequela (S) encounters; using the wrong encounter character is a common error.
• Code any associated open wounds or other injuries to the face separately, following sequencing guidelines.
