A county clinic note documents both acute and chronic sinusitis during the same encounter, and the ICD-10-CM chapter for that condition provides combination and sequencing guidance. How should the physician-based coder approach code assignment?
Select an answer to reveal the explanation.
Short Explanation
Think of acute and chronic like a flash flood and a long rainy season hitting the same road. When the chart names both, you don’t just pick a favorite—you open that chapter’s rulebook. Combination codes or sequencing notes tell you how ICD-10-CM wants them reported.
Full Explanation
When documentation states only acute or only chronic, code the documented status. When both are documented for the same condition, ICD-10-CM Official Guidelines and chapter-specific instructions may require a combination code or a defined sequencing order rather than two free-standing defaults. Physician-office coders should apply those chapter rules instead of inventing a one-size-fits-all acute-only or chronic-only choice.
