2025 ICD-10-CM code R57

Shock, not elsewhere classified.

This code should only be used as a last resort when a more specific code for the type of shock cannot be identified after appropriate investigation.It is important to document the reasons why a more specific diagnosis could not be made.

Medical necessity for the use of this code is established when a patient presents with signs and symptoms of shock, but the specific etiology is undetermined after initial assessment.

Clinicians should thoroughly investigate and document the specific type of shock present as other codes are available to capture those details. Only when no more specific code can be applied, shall this code be used.

IMPORTANT:Use more specific codes if available (e.g., R57.0 for Cardiogenic shock, R57.1 for Hypovolemic shock, R57.2 for Septic shock).Do not use this code if the cause of the shock is known.

In simple words: This code represents a state of shock where the body is not getting enough blood flow, but the cause is not specifically identified.It's a general term for shock when more specific information isn't available.

Shock, not elsewhere classified. This code is used for shock not otherwise specified, unknown etiology, or transient. It excludes anaphylactic shock NOS (T78.2), obstetric shock (O75.1), postprocedural shock (T81.1), psychic shock (F43.0), and other specific types of shock.

Example 1: A patient presents to the emergency room with symptoms of shock - low blood pressure, rapid heart rate, and altered mental status.Initial investigations do not reveal a clear cause, and the physician documents "shock, not elsewhere classified.", A patient experiences a sudden drop in blood pressure during a surgical procedure.The cause of the shock is not immediately apparent, and the anesthesiologist documents "R57" as a provisional diagnosis., A patient arrives at the hospital after a motor vehicle accident with signs of shock.While traumatic shock is suspected, the clinical picture is complex, and further investigations are needed to confirm the diagnosis."R57" is used as a placeholder until a more definitive diagnosis can be made.

Detailed clinical documentation of the signs and symptoms of shock, along with the results of any diagnostic tests performed to determine the cause, are essential. If a more specific diagnosis is later determined, the documentation should reflect this change.

** The importance of thoroughly investigating the cause of the shock to determine if a more specific code can be assigned cannot be overstated.If a more definitive diagnosis is not available, and R57 has been coded, make sure to add the details into documentation why more specific diagnosis is not available and why is R57 coded.
