T17.998D ICD-10-CM Code: Other foreign object in respiratory tract, part unspecified causing other injury, subsequent encounter

T17.998D is the ICD-10-CM diagnosis code for other foreign object in respiratory tract, part unspecified causing other injury, subsequent encounter. T17.998D sits in the ICD-10-CM chapter for injury, poisoning and certain other consequences of external causes (s00-t88), within the section covering effects of foreign body entering through natural orifice (t15-t19).

T17.998D is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

T17.998D is a billable ICD-10-CM code that can be reported on claims but does not currently contribute to a Medicare Advantage member's RAF score under any CMS risk adjustment model (V28, V24, ESRD, or RxHCC). Coders reviewing T17.998D should check whether additional documentation would support a more specific child code in the same hierarchy that does map to a payment HCC, capturing the correct specificity is the highest-impact RAF improvement available within accurate coding.
