Final answer:
ICD-10-CM guideline I.B.11 indicates that an impending condition that has not occurred by discharge should not be coded as if the condition occurred. Instead, symptoms or conditions leading to the concern should be coded. This is vital for accurate clinical documentation and insurance processing.
Step-by-step explanation:
According to ICD-10-CM guideline I.B.11, when a physician documents an impending condition that has not occurred by the time of discharge, the appropriate action is not to use a diagnosis code for the actual condition, since it did not occur. Instead, the coder should find a suitable code representing the current condition or symptoms that led to the concern for the impending event.
For instance, if a patient has chest pain and there's a concern for an impending myocardial infarction, the myocardial infarction should not be coded since it hasn't happened. The chest pain, or any other present symptoms, should be coded instead. ICD codes are essential for clinical fields in processes such as ordering laboratory tests, prescribing treatments, recording procedures, processing claims for reimbursement, and classifying diseases for morbidity and mortality statistics.
