About R57

R57 is the ICD-10-CM diagnosis code for shock, not elsewhere classified. It belongs to block R50-R69 (general symptoms and signs) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: R57.0 (shock), R57.1 (shock), R57.8 (shock) and R57.9 (unspecified).

Don't report R57 together with the conditions in its Excludes1 note: 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-) and 9 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
