Corrosion of first degree of buttock, sequela

This code signifies a healed or residual effect from a first-degree chemical burn (corrosion) that previously affected the buttock area. It indicates that the acute injury has resolved, but there are lasting consequences or late effects.

Apply this code when documenting a patient presenting with a long-term complication or sequela directly attributable to a past first-degree chemical burn of the buttock. This would include conditions like scarring, pigmentation changes, or chronic sensitivity in the affected area, where the original burn is no longer active.

• Always assign an external cause code (V00-Y99) to identify the circumstances of the original corrosion, if known.
• Do not use this code for active, acute, or current first-degree chemical burns; use the appropriate acute corrosion code.
• Ensure documentation clearly links the current condition to a past first-degree chemical burn of the buttock.
