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 requires a defined approach character, and percutaneous versus open (or other approaches) produce different valid codes. Ambiguous wording such as a vague catheter-based description without a clear approach is a documentation gap that affects code assignment. Coders should not default to a common approach or omit an inpatient procedure that was clearly performed. A focused query for approach detail is the appropriate step before final PCS coding.
