Lac w/o fb of unsp lesser toe(s) w damage to nail, sequela

This code signifies a healed injury or a residual effect from a past laceration to an unspecified lesser toe, where the laceration did not involve a foreign body but did cause damage to the toenail. The "sequela" designation indicates that this code is used to report the late effects or complications of the original injury, rather than the acute injury itself.

Use this code when documenting a patient presenting with a chronic condition or long-term consequence directly attributable to a previous laceration of a lesser toe, such as nail deformity, chronic pain, or functional impairment. This code is appropriate when the initial injury has healed, but its lasting impact on the toe and nail requires ongoing medical attention or documentation.

• Always assign a sequela code as a secondary diagnosis, with the primary diagnosis describing the nature of the sequela (e.g., chronic pain, nail deformity).
• Ensure documentation clearly links the current condition to a past laceration of a lesser toe with nail damage.
• Do not use this code for acute lacerations; instead, use the appropriate acute laceration code from the S91.21- series.
