Questions About R57.1Overview

Is R57.1 (Shock, not elsewhere classified) a billable code?

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

What MS-DRG does R57.1 group to?

When hypovolemic shock is the principal diagnosis on an inpatient stay, it groups to MS-DRG 870, 871, 872, with relative weights from 1.0233 to 6.9118 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R57.1 be a principal diagnosis?

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

What is the ICD-9 equivalent of R57.1?

Under the General Equivalence Mappings, hypovolemic shock converts to ICD-9-CM 785.59 (shock w/o trauma NEC). The mapping is approximate, so confirm the match fits the documentation.

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.
