About coding thigh corrosion
The ICD-10-CM code for thigh corrosion is T24.419 (Corrosion of unspecified degree of unspecified thigh). The official index lists 11 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T24.419.
Within T24.41, choose T24.419 (unspecified thigh) only when documentation doesn't support a more specific option: right thigh (T24.411) and left thigh (T24.412).
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.
