A: Coders can assign diagnosis codes based on documentation of any licensed independent provider that provides direct care to the patient. This includes physicians, nurse practitioners, and physician assistants who provide care to the patient during this encounter. Thus, the documentation of ED physicians or other providers (nurse practitioners and physician assistants) can be used to assign a code.

 

This comes with two notes of caution, however. First, this documentation must not conflict with the attending physician. If the documentation conflicts, then query for clarification. Second, if the ED physician documents a diagnosis, but you see no evidence of treatment or monitoring continued through the inpatient stay, query for the significance of the diagnosis.

 

As for the second piece of your question, diagnosis codes cannot be assigned based on test results or imaging. The documentation of radiologists and pathologists cannot be used to assign diagnosis codes, as such physicians do not provide direct patient care. Coders or clinical documentation improvement (CDI) specialists would need to query the attending provider to assign the appropriate diagnosis code.

 

Coding Clinic for ICD-10-CM/PCS has published guidance regarding the use of such reports to further specify the location of a fracture or cerebrovascular accident from imaging. But we first must have the diagnosis as documented by the attending physician or provider responsible for the direct care of the patient.
