Questions About R57.0Overview

Is R57.0 (Shock, not elsewhere classified) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report cardiogenic shock on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does R57.0 group to?

When cardiogenic shock is the principal diagnosis on an inpatient stay, it groups to MS-DRG 291, 292, 293, with relative weights from 0.5660 to 1.2838 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R57.0 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the cardiogenic shock is established, that condition takes the principal position instead.

What is the ICD-9 equivalent of R57.0?

Under the General Equivalence Mappings, cardiogenic shock converts to ICD-9-CM 785.51 (cardiogenic shock). The mapping is a direct match.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
