Q: Can you explain how we would code a percutaneous transluminal coronary angioplasty (PTCA) using ICD-9-CM vs. ICD-10-PCS? 

A: For the purposes of your question, let’s consider a patient who undergoes a PTCA involving one site and one stent.
First, note that ICD-10-PCS classifies the coronary arteries as a single body part that is further specified by the number of sites treated—not by the name or number of arteries.
In ICD-9-CM, report the following codes:
  • 36.06 (insertion of non-drug-eluting coronary stent)
  • 00.66 (angioplasty [PTCA])
  • 00.45 (insertion of one vascular stent)
  • 00.40 (procedure on single vessel)
  • 00.44 (procedure on vessel bifurcation)
In ICD-10-PCS, report 02703D6. Each component of this code denotes the following:
  • 0 (medical/surgical [procedure])
  • 2 (heart and great vessels [body system])
  • 7 (dilation [root operation])
  • 0 (coronary artery, one site [body part])
  • 3 (percutaneous [approach])
  • D (intraluminal device [bare metal stent])
  • 6 (bifurcation)
As stated previously, the ICD-9-CM codes focus on capturing the number of stents and vessels whereas ICD-10-PCS focuses on capturing the number of sites treated. One ICD-10-PCS code provides all of the necessary information to completely capture this procedure.
