What type of denial is highlighted when a review contractor states the principal diagnosis was changed to bronchitis?

• A. DRG
• B. DRG with clinical validation
• C. Medical necessity
• D. Level of care

Answer: (B)

The correct answer is that the scenario describes a denial related to DRG with clinical validation. This type of denial occurs when the review contractor challenges the accuracy or appropriateness of the principal diagnosis documented, in this case, changing it to bronchitis.

In a clinical validation denial, the focus is not merely on the coding itself but on whether the documentation supports the diagnosis in question based on clinical evidence. The contractor's statement about changing the principal diagnosis suggests they found discrepancies or lack of clinical backing for the original diagnosis. Therefore, it emphasizes the need for the documentation to reflect a diagnosis that aligns with the patient's clinical condition, which is crucial for DRG assignment and reimbursement.

This highlights the importance of having comprehensive and precise clinical documentation that can substantiate the codes assigned for accurate reimbursement. It also underlines the necessity for healthcare providers to ensure that their documentation truly reflects the patient's medical conditions as supported by clinical evidence.
