About S22.41XA

S22.41XA is the ICD-10-CM diagnosis code for multiple fractures of ribs, right side, initial encounter for closed fracture. It belongs to category S22 (fracture of rib(s), sternum and thoracic spine), block S20-S29 (injuries to the thorax) 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 for closed fracture: use it while the patient is receiving active treatment for the condition.

Code first: , if applicable, spinal cord injury (S24.0-, S24.1-).

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 183 (Major Chest Trauma with MCC, relative weight 1.4903), DRG 184 (Major Chest Trauma with CC, relative weight 1.0647), DRG 185 (Major Chest Trauma without CC/MCC, relative weight 0.7715), DRG 963 (Other Multiple Significant Trauma with MCC, relative weight 2.6363), DRG 964 (Other Multiple Significant Trauma with CC, relative weight 1.4972) and DRG 965 (Other Multiple Significant Trauma without CC/MCC, relative weight 1.0059), in MDC 04 (Diseases and Disorders of the Respiratory System) 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 807.02 (closed fracture of two ribs), 807.03 (closed fracture of three ribs), 807.04 (closed fracture of four ribs) and 5 more.
