Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)

T88.53XA is a billable diagnosis code used to specify a medical diagnosis of unintended awareness under general anesthesia during procedure, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

T88.53XA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like unintended awareness under general anesthesia during procedure. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

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.
