A brief procedure note for a hospital inpatient states that a catheter-based intervention was performed but does not clearly document whether the approach was percutaneous or open. Before ICD-10-PCS coding, what is the best action?

Short Explanation
PCS approach is like choosing the door you used to enter a building — percutaneous and open are different doors with different codes. If the note leaves that door ambiguous, you query before you build the PCS string. Defaults are not documentation.
Full Explanation
ICD-10-PCS approach is a required character that changes the code. When a brief inpatient procedure note states a catheter-based intervention was performed but does not clearly document whether the approach was percutaneous or open, the best action is to query to clarify the approach. Selecting percutaneous by default for any catheter-based wording assumes an approach the note never confirmed. Coding an open approach because inpatient surgery usually implies an incision substitutes stereotyping for documentation. Omitting the procedure code until outpatient billing rules apply abandons inpatient procedure reporting instead of resolving a missing PCS character. Exam caveat: "catheter-based" language often correlates with percutaneous approach but is not a universal substitute for documented approach when the note is ambiguous or suggests cutdown/open elements. Operational check for county interventional cases: read entire operative text for access description; if approach remains unclear, query before assigning the PCS approach character. This discipline protects patients, supports accurate public reporting for municipal hospitals, and keeps the coded abstract defensible when auditors compare codes to the authenticated record.
