About T17.508S
T17.508S is the ICD-10-CM diagnosis code for unspecified foreign body in bronchus causing other injury, sequela. It belongs to category T17 (foreign body in respiratory tract), block T15-T19 (effects of foreign body entering through natural orifice) and chapter 19 (injury, poisoning and certain other consequences of external causes). 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.
In MS-DRG v44.0, it is part of the grouping logic for DRG 913 (Traumatic Injury with MCC, relative weight 1.5455) and DRG 914 (Traumatic Injury without MCC, relative weight 0.9285), in MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 908.5 (late effect of foreign body in orifice).
