Unsp open wound of l mid finger w damage to nail, sequela

This code signifies a past open wound on the left middle finger that involved damage to the nail, where the specific nature of the wound (e.g., laceration, puncture) was not documented. The "sequela" designation indicates that this code is used for complications or conditions arising directly from the initial injury, even after the acute phase has passed.

This code is appropriate for documenting long-term effects or complications of a previously sustained, unspecified open wound to the left middle finger with nail damage. Examples include chronic nail deformities, non-healing nail bed issues, or persistent pain directly attributable to the original injury. It should be used when the patient is presenting for treatment of these residual conditions.

• Always ensure documentation clearly links the current condition to the original injury as a sequela.
• Do not use this code for the initial acute injury; instead, use an acute open wound code.
• Verify laterality (left) and digit (middle finger) are accurately documented.
