Corrosion of first deg mult sites of right wrs/hnd, sequela

This code describes the long-term effects or complications arising from a first-degree corrosion injury (chemical burn) that affected multiple sites on the patient's right wrist and hand. It indicates that the acute phase of the injury has passed, and the patient is now presenting with residual issues related to the original chemical exposure.

Use this code when documenting a patient encounter for follow-up care, evaluation of chronic symptoms, or treatment of lasting complications (e.g., scarring, pigment changes, sensitivity) directly attributable to a first-degree chemical burn on the right wrist and hand. This applies when the original injury is no longer acute and the focus is on the sequelae.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the corrosion.
• Ensure documentation clearly links the current sequela to the past first-degree corrosion of the right wrist and hand.
• Do not use this code for acute corrosion injuries; instead, use the appropriate acute T23.0-T23.4 codes.
