Corros unsp degree of unsp mult fngr, not inc thumb, sqla

This code signifies the long-term effects or complications arising from a chemical burn of an unspecified severity affecting multiple fingers, excluding the thumb. It indicates that the initial injury has healed, but residual issues related to the corrosion are still present.

Use this code when documenting a patient presenting with a chronic condition or permanent damage to multiple fingers (not including the thumb) that is a direct result of a past chemical burn. This applies to situations where the acute phase of the injury has passed, and the current encounter addresses the sequelae, such as scarring, contractures, or chronic pain.

• Always use an external cause code (V00-Y99) in conjunction with this code to describe the circumstances of the original injury.
• Ensure documentation clearly specifies that the affected fingers are not the thumb and that the current condition is a sequela.
• Do not use this code for acute chemical burns; instead, use the appropriate acute corrosion code.
