ICD-10-CM R57.0
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

R57.0 is a billable ICD-10-CM diagnosis code for cardiogenic shock. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 291 through 293. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. This status applies only when the patient is discharged alive, and not when the principal diagnosis is one of 48 closely related codes. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Shock.

For Medicare Advantage risk adjustment, R57.0 maps to CMS-HCC Category 213 (Cardio-Respiratory Failure and Shock) under the V28 model, adding a risk factor of about 0.370 for a community, non-dual, aged beneficiary in payment year 2026.

Questions About R57.0Overview

What is the ICD-10 code for cardiogenic shock?

The ICD-10-CM code for cardiogenic shock is R57.0 (sometimes written as R570). It is billable on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

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.

Is R57.0 a CC or MCC?

CMS lists R57.0 as an MCC (major complication or comorbidity) for FY 2026. Reported as a secondary diagnosis, it places the inpatient stay in the highest-weighted DRG of its severity family. It carries this status only when the patient is discharged alive. It does not count when the principal diagnosis is one of the 48 closely related codes in its exclusion list.

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 HCC is R57.0?

R57.0 (cardiogenic shock) maps to CMS-HCC Category 213 (Cardio-Respiratory Failure and Shock), commonly written as HCC 213, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2026. It mapped to HCC 84 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. It does not map to any RxHCC in the Part D prescription drug model.

Does R57.0 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, R57.0 adds a risk adjustment factor of about 0.370 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.258 to 0.662 depending on the payment segment). A more severe related category (HCC 211 and HCC 212) supersedes it when both are reported. See the full factor table on the HCC 213 category page.
