X50.9Other and unspecified overexertion or strenuous movements or postures

X50.9 is the ICD-10-CM diagnosis code for other and unspecified overexertion or strenuous movements or postures. It belongs to category X50 (overexertion and strenuous or repetitive movements), block X50 (overexertion and strenuous or repetitive movements) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within X50, choose X50.9 (Other and unspecified overexertion or strenuous movements or postures) only when documentation doesn't support a more specific option: overexertion from strenuous movement or load (X50.0), overexertion from prolonged static or awkward postures (X50.1) and overexertion from repetitive movements (X50.3).

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 was added in FY2017, effective October 1, 2016.
