Sprain of joints and ligaments of oth parts of head, sequela

This code describes a sprain affecting the ligaments or joints of the head, excluding those of the jaw, cervical spine, or other specifically classified areas. It indicates a past injury where the patient is now experiencing residual effects or complications. These sequelae could include chronic pain, stiffness, or limited range of motion resulting from the original sprain.

Use this code when documentation clearly indicates a sprain of an unspecified joint or ligament within the head region, and the encounter is for the treatment or evaluation of a residual condition or late effect of that sprain. This applies to situations where the initial acute injury has resolved, but the patient continues to experience symptoms directly attributable to the original sprain. Documentation should specify "sequela" or "late effect" of a head sprain.

• Ensure the documentation explicitly states "sequela" or "late effect" to justify using the 7th character 'S'.
• Do not use for acute sprains; refer to the acute injury codes for the initial encounter.
• Always sequence this code after the primary diagnosis describing the specific sequela (e.g., chronic pain, stiffness).
