S17.9XXACrushing injury of neck, part unspecified, initial encounter

S17.9XXA is the ICD-10-CM diagnosis code for crushing injury of neck, part unspecified, initial encounter. It belongs to category S17 (crushing injury of neck), block S10-S19 (injuries to the neck) 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 "A" means initial encounter: use it while the patient is receiving active treatment for the condition.

Use an additional code for all associated injuries, such as: injury of blood vessels (S15.-), open wound of neck (S11.-), spinal cord injury (S14.0, S14.1-) and vertebral fracture (S12.0--S12.3-).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC, relative weight 5.6154), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC, relative weight 4.381), DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC, relative weight 2.7307), DRG 913 (Traumatic Injury with MCC, relative weight 1.5455), DRG 914 (Traumatic Injury without MCC, relative weight 0.9285), DRG 963 (Other Multiple Significant Trauma with MCC, relative weight 2.6363) and 2 more, in Pre-MDC, MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs) and MDC 24 (Multiple Significant Trauma), 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 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 925.2 (crushing injury of neck).
