Laceration w/o fb of unsp finger w damage to nail, sequela

This code describes a long-term complication or late effect resulting from a laceration to an unspecified finger, where the original injury did not involve a foreign body but did cause damage to the nail. The sequela could manifest as nail deformity, chronic pain, or functional impairment related to the initial nail damage.

This code is appropriate for documenting a patient presenting for treatment of a residual condition or late effect directly attributable to a past laceration of an unspecified finger that involved nail damage. This would be used when the acute phase of the original injury has passed, and the current encounter addresses the lasting consequences.

• Always assign a sequela code (ending in 'S') as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past finger laceration with nail involvement.
• Do not use this code for acute injuries; refer to the appropriate acute laceration codes.
