Corrosion of unsp degree of unspecified wrist, sequela

This code signifies the long-term effects or complications arising from a chemical burn (corrosion) of an unspecified degree affecting an unspecified wrist. It indicates that the acute injury has healed, but residual problems related to the corrosion persist.

Apply this code when documenting conditions such as chronic pain, scarring, limited range of motion, or nerve damage in the wrist that are directly attributable to a past corrosive chemical burn. This code is appropriate when the specific degree of the original burn and the laterality of the wrist are not documented.

• Requires a seventh character "S" to denote sequela, indicating a late effect.
• Always sequence this code after the code(s) identifying the specific nature of the sequela (e.g., scar, contracture).
• Do not use for acute corrosive injuries; those require codes from the T20-T25 range without the "S" seventh character.
