About X50.9XXS
X50.9XXS is the ICD-10-CM diagnosis code for other and unspecified overexertion or strenuous movements or postures, sequela. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
The 7th character "S" means sequela: use it for complications or conditions that arise as a direct result of the original condition.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It was added in FY2017, effective October 1, 2016.
Before ICD-10, this condition was coded in ICD-9-CM as E929.8 (late effects of other accidents).
