Corros 2nd deg mul left fngr (nail), not inc thumb, sequela

This code indicates a long-term complication or residual effect stemming from a second-degree corrosion injury to multiple fingers on the left hand, excluding the thumb. This type of injury involves damage to the epidermis and dermis, often presenting with blistering, and the sequela refers to ongoing issues after the initial healing phase.

Use this code when documenting a patient presenting with a chronic problem, such as scarring, contracture, or persistent pain, directly attributable to a past second-degree chemical burn affecting multiple left fingers (excluding the thumb). This code is appropriate for follow-up encounters addressing these lasting effects, not the initial acute injury.

• Ensure the medical record clearly links the current condition to a previous second-degree corrosion of the specified fingers.
• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., scar, contracture).
• Verify that the injury involved multiple fingers on the left hand and specifically excluded the thumb.
