R57.9 — Shock, unspecified
Is R57.9 billable?
Yes, but R57.9 is an unspecified code. R57.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, R57.9 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting R57.9 — the more specific alternatives are listed below.

Which MS-DRGs does R57.9 group to?
R57.9 sits in MDC 05 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 291Heart Failure and Shock with MCCmedical
- 292Heart Failure and Shock with CCmedical
- 293Heart Failure and Shock without CC/MCCmedical
As a secondary diagnosis, R57.9 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from R57
The conditions below can never be reported together with R57.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- anaphylactic shock NOS (T78.2)
- anaphylactic reaction or shock due to adverse food reaction (T78.0-)
- anaphylactic shock due to adverse effect of correct drug or medicament properly administered (T88.6)
- anaphylactic shock due to serum (T80.5-)
- electric shock (T75.4)
- obstetric shock (O75.1)
- postprocedural shock (T81.1-)
- psychic shock (F43.0)
- shock complicating or following ectopic or molar pregnancy (O00-O07, O08.3)
- shock due to anesthesia (T88.2)
- shock due to lightning (T75.01)
- traumatic shock (T79.4)
- toxic shock syndrome (A48.3)
Excludes2 — not included here — inherited from Chapter 18
The conditions below are not part of R57.9, but a patient may have both at the same time. When documentation supports it, R57.9 and the excluded code may both be reported.
