Corrosion of first degree of left axilla, sequela

This code signifies a first-degree chemical burn (corrosion) affecting the left armpit area, where the initial injury has healed but is still causing ongoing problems or complications. These sequelae could include scarring, pigment changes, chronic pain, or functional limitations resulting from the original corrosion.

Apply this code when documenting the long-term effects or complications stemming from a first-degree chemical burn to the left axilla. This is appropriate for follow-up encounters where the acute injury has resolved, but the patient is being treated for residual issues directly attributable to the past corrosion.

• Ensure documentation clearly links the current condition to a past first-degree chemical burn of the left axilla.
• Always use this 'S' (sequela) seventh character for conditions that are late effects of an injury.
• Code any specific sequelae (e.g., scar, chronic pain) in addition to this code, if applicable and documented.
