Corros second degree of single l finger except thumb, sqla

This code describes a second-degree chemical burn (corrosion) affecting a single finger on the left hand, excluding the thumb, where the acute injury has resolved and residual effects or complications are now being treated. These sequelae could include scarring, contractures, chronic pain, or functional impairment resulting from the initial corrosion.

Apply this code when documenting the long-term effects or complications of a second-degree chemical burn to a single left finger (not the thumb), after the initial healing phase. This is appropriate for follow-up encounters addressing ongoing issues directly attributable to the past chemical injury.

• Requires a seventh character "S" to indicate sequela, meaning the residual effects of a past injury.
• Do not use for acute chemical burns; those require an acute seventh character (A, D, or S for initial, subsequent, or sequela, respectively, for the acute phase).
• Always code the specific sequela (e.g., scar, contracture) in addition to this code to fully describe the patient's condition.
