Other specified injuries of thyroid gland, sequela

This code signifies a long-term or late effect resulting from a previously sustained injury to the thyroid gland, where the specific nature of the injury is not otherwise classified. It indicates that the initial acute injury has resolved, but its lasting consequences are still present and require ongoing management.

Apply this code when documenting a patient presenting with a chronic condition or complication directly attributable to a past, non-specific injury of the thyroid gland. Documentation should clearly link the current sequela to a prior thyroid trauma, such as persistent dysfunction, scarring, or other specified but not otherwise classifiable long-term effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., hypothyroidism due to trauma).
• Ensure documentation explicitly states the injury is to the thyroid gland and that the current condition is a residual effect.
• Do not use for acute injuries; this code is exclusively for sequelae, indicated by the "S" seventh character.
