The attending physician is the correct answer and this scenario is adapted from an official ACDIS CCDS sample item addressing conflicting medical-record documentation.
ICD-10-CM coding depends on provider documentation, but when clinically significant documentation conflicts within the record, the discrepancy must be clarified rather than resolved independently by the coder or CDI specialist. The FY 2026 Official Guidelines specifically state that when medical-record documentation conflicts, the patient's provider should be queried for clarification.
In the inpatient environment, the attending provider is generally responsible for synthesizing the patient's diagnoses and final clinical picture. A consultant's documentation may supply essential clinical information and may support code assignment when there is no conflict, but conflicting descriptions of heart-failure type or acuity should not simply be selected based on which diagnosis produces the higher-severity code.
The query should identify the conflicting statements objectively and request clarification of the clinically appropriate diagnosis. It should not suggest which diagnosis should be selected or mention reimbursement consequences.
This concept is central to CDI because unresolved contradictions can affect MS-DRG assignment, risk adjustment, severity measurement, quality reporting, and the clinical integrity of the record.
