About coding palm corrosion
The ICD-10-CM code for palm corrosion is T23.459 (Corrosion of unspecified degree of unspecified palm). The official index lists 11 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T23.459.
Within T23.45, choose T23.459 (unspecified palm) only when documentation doesn't support a more specific option: right palm (T23.451) and left palm (T23.452).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
