About S20.213S

S20.213S is the ICD-10-CM diagnosis code for contusion of bilateral front wall of thorax, sequela. It belongs to category S20 (superficial injury of thorax), 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 "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 604 (Trauma to the Skin, Subcutaneous Tissue and Breast with MCC, relative weight 1.453) and DRG 605 (Trauma to the Skin, Subcutaneous Tissue and Breast without MCC, relative weight 0.9079), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), 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 was added in FY2021, effective October 1, 2020.
