About coding thumb sprain
The ICD-10-CM code for thumb sprain is S63.60 (Unspecified sprain of thumb). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S63.60.
Within S63.6, choose S63.60 (Unspecified sprain of thumb) only when documentation doesn't support a more specific option: unspecified sprain of other and unspecified finger(s) (S63.61), sprain of interphalangeal joint of thumb (S63.62), sprain of interphalangeal joint of other and unspecified finger(s) (S63.63), sprain of metacarpophalangeal joint of thumb (S63.64), sprain of metacarpophalangeal joint of other and unspecified finger(s) (S63.65), other sprain of thumb (S63.68) and other sprain of other and unspecified finger(s) (S63.69).
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.
