About ICD-10-CM S28
ICD-10-CM code S28 represents Crushing injury of thorax, and traumatic amputation of part of thorax. This is a non-billable header code in the Injury, Poisoning, and External Causes chapter (block S28). The 2026 edition of ICD-10-CM S28 became effective on October 1, 2025. Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.
Coding Tips for S28
Specialist guidance from the PayerReady Medical Coding Team. Specificity warnings, HCC capture rules, sequencing notes.
Injury codes require a 7th character: A (initial encounter, active treatment), D (subsequent, healing/recovery), S (sequela, late effect of original injury). Codes with fewer than 6 characters need the placeholder X to bring them to 6 characters before adding the 7th. Wrong or missing 7th character is the #1 cause of injury claim denials.
