Unsp injury of muscle, fascia and tendon at neck level, subs

This code signifies an injury to the muscles, fascia, or tendons located in the neck region, where the specific nature of the injury (e.g., strain, tear) is not documented. The "D" seventh character indicates that this is a subsequent encounter for the injury, meaning the patient is receiving routine care during the healing or recovery phase.

Use this code when a patient presents for follow-up care, such as physical therapy, medication refills, or re-evaluation, for an unspecific neck muscle, fascia, or tendon injury. Documentation should clearly state "unspecified neck injury" and indicate that the encounter is for ongoing treatment or recovery, not the initial presentation.

• Ensure documentation explicitly states "unspecified" if the specific injury type is unknown.
• Verify the seventh character "D" is appropriate for subsequent care; avoid "A" (initial) or "S" (sequela).
• Always sequence this code after any definitive diagnosis codes if available, or as the primary diagnosis if the unspecified injury is the sole reason for the encounter.
