Laceration w/o fb of right thumb w damage to nail, sequela

This code signifies a past injury to the right thumb, specifically a laceration that did not involve a foreign body, and which also caused damage to the nail. The "sequela" designation indicates that this code is used for conditions that are residual effects or complications of the original injury, occurring after the acute phase has passed.

Use this code when documenting a patient presenting with a chronic issue, scar, deformity, or other long-term consequence directly attributable to a previous laceration of the right thumb that included nail damage. This is appropriate for follow-up visits addressing the lasting impact of the initial trauma, rather than the acute injury itself.

• Requires a 7th character of 'S' for sequela, indicating a late effect.
• Do not use for the initial treatment of the acute laceration; that would require an 'A' or 'D' 7th character.
• Always link this sequela code to an external cause code (V00-Y99) if the original cause of the injury is known and relevant to the current encounter.
