The Complexity of Root Operations in ICD-10-PCS

The Complexity of Root Operations in ICD-10-PCS

Inpatient coders are faced with the daunting task of determining the “intent of procedure” when compliantly coding inpatient procedures.

With the inception of the 2017 updates, which became effective October 1, 2016, we are again faced with the lingering questions of the “intent of the procedure” when applying PCS codes. As we continue to see revisions to the PCS coding system, it is important to review Root Operations to remain compliant when coding procedures.

We will look into the coding guidelines and provide some examples of PCS coding in this article. It is always a benefit to start with the past, and move forward. We will start with coding guidelines.

Root Operations

According to 2017 ICD-10-PCS Official Guidelines for Reporting, Guideline A11, “the coder is responsible for selecting the root operation that most closely matches the intent of the procedure.”

The interpretation of this guideline is the coder is not to rely on the term the physician documents to arrive at the correct PCS code for the procedure performed. With the inception of ICD-10-PCS coding, we are reminded that the documentation of procedures from the physician may not always be the actual intent of the procedure.

For example, the physician documents excision of the inner/outer quadrant of the left breasts; however, she takes the entire left breast during the procedure. As the definition of Excision states, “Cutting out or off, without replacement, a portion of a body part;” this Root operation would be incorrect. The physician actually performed a Resection, “Cutting out or off, without replacement, all of a body part.” Taking this into account, coders need to know all nine root groups of operations to correctly identify the correct PCS table and compliantly code the procedure.

Let’s look at the updated PCS definitions released for 2017 from the Centers for Medicare and Medicaid Services.

Control

Control underwent a complete definition revision for the 2017 update. The definition now states, Stopping or attempting to stop post-procedural or other acute bleeding.” The revision added the terms Other Acute Bleeding to the main definition. CMS also emphasizes the prudence of if a more definitive procedure is needed to control the bleeding (i.e., Bypass, Detachment, Excision, Extraction, Reposition, Replacement, and/or Resection), the root operation is coded instead of the root operation Control.

Creation

Prior to the 2017 update release, Creation was defined as “making a new genital structure that does not physically take the place of a body part.” The new definition revision now states, “Putting in or on a biological or synthetic material to form a new body part.” This clears up a long-time issue for coders as there was not a logical operation when the Creation would be considered. This also changed the focus of Creation to additional body systems where prior, Creation was only used for sex-change procedures.

Examples of Procedure Coding within PCS:

Root Operation Definition PCS Code Example
Alteration Alteration of Bilateral Breast with synthetic substitute, open approach

 

0H0V0JZ
Bypass Bypass 4+ coronary arteries from coronary artery with autologous venous tissue, open approach 0213093
Change Change tracheostomy device in trachea, external approach

 

0B21XFZ
Control Control of post-tonsillectomy hemorrhage 0W33XZZ
Creation Creation of Mitral valve from common atrioventricular valve using Zooplastic tissue, open approach 024G082
Destruction Destruction of back skin, multiple, external approach 0H56XZD
Detachment Detachment at right lower leg, high, open approach 0Y6H0Z1
Dilation Dilation of left common carotid artery, bifurcatioin, with three drug-eluting intraluminal devices, open approach 037J066
Division Division of left upper femur, percutaneous approach 0Q873ZZ
Drainage Drainage of right inguinal region with drainage device, percutaneous approach 0Y9530Z
Excision Excision of cerebral meninges, open approach 00B10ZZ
Extirpation Extirpation of matter from coronary artery, two arteries using orbital artherectomy technology, percutaneous approach, new technology group 1 X2C1361
Extraction Extraction of right lens (eye), percutaneous approach 0BDJ3ZZ
Fragmentation Fragmentation in right ureter, via natural or artificial opening, endoscopic 0TF68ZZ
Fusion Fusion of right hip joint with internal fixation device, percutaneous endoscopic approach 0SG944Z
Insertion Insertion of endotracheal airway into trachea, via natural or artificial opening 0BH17EZ
Inspection Inspection of lower intestinal tract, via natural or artificial opening endoscopic (Diagnostic Colonoscopy) 0DJD8ZZ
Map Map conduction mechanism, percutaneous approach 02K83ZZ
Occlusion Occlusion of bilateral fallopian tubes with intraluminal device, percutaneous endoscopic approach 0UL74DZ
Reattachment Reattachment of left lower arm and wrist tendon, percutaneous endoscopic approach 0LM64ZZ
Release Release right hand tendon, open approach (Trigger Finger Release) 0LN70ZZ
Removal Removal of drainage device from right upper extremity, percutaneous endoscopic approach 0XP640Z
Repair Repair right lower leg tendon, open approach 0LQN0ZZ
Replacement Replacement of right knee joint with synthetic substitute, cemented, open approach 0SRC0J9
Reposition Reposition right carpal, percutaneous approach 0PSM3ZZ
Resection Resection of descending colon, percutaneous endoscopic approach 0DTM4ZZ
Restriction Restriction of lower femoral vein, open approach 06VN0ZZ

To remain compliant when coding PCS procedures, we must always have the correct intent of procedures at hand. We should also ensure to correctly follow Coding and Reporting Guidelines inherently.  It is also important that the documentation lead the coder to the correct PCS code based on the intent of the procedure. If the documentation is not clear, query!
