3 1 Differences between ICD-9-CM and ICD-10-PCS (Karla R Lovaasen) ICD-9-CM ICD-10-PCS Structure Similar to ICD-9 Diagnosis Codes Structure Different with Use of Tables Limited Number of Codes Expandable with Unlimited Number of Codes Codes are 3 to 4 Digits with Decimal All Codes 7 Characters, NO Decimal after 2 nd Digit Codes are Numeric Codes are Alphanumeric , A-Z (except I and O) Combination Codes Separate Procedures Performed at Same Time are Coded Separately Page 1-1 of 1 (Differences)

4 2 Organization of ICD-10-PCS (Karla R Lovaasen) ICD-10-PCS Sections (CMS, Development of ICD-10-PCS) ICD-10-PCS Has a Seven (7) Character Alphanumeric Code Structure Each Character Contains Up to 34 Possible Values Each Value Represents a Specific Option for the General Character Definition (e.g., Stomach is One of the Values for the Body Part Character) Digits 0-9 and 24 Letters A-H,J-N and P-Z May be Used in Each Character (Letters O and I are NOT Used in Order to Avoid Confusion With Digits 0 And 1) Procedures are Divided Into Sections That Identify the General Type of Procedure (e.g., Medical and Surgical, Obstetrics, Imaging) 1st Character of the Procedure Code Always Specifies the Section 0. Medical and Surgical 1. Obstetrics 2. Placement 3. Administration 4. Measurement and Monitoring 5. Extracorporeal Assistance and Performance 6. Extracorporeal Therapies 7. Osteopathic 8. Other Procedures 9. Chiropractic B. Imaging C. Nuclear Medicine D. Radiation Oncology F. Physical Rehabilitation and Diagnostic Audiology G. Mental Health H. Substance Abuse Treatment (CMS, Development of ICD-10-PCS) 2nd Through 7th Characters Mean the Same Thing Within Each Section, But May Mean Different Things In Other Sections In All Sections, the 3rd Character Specifies the General Type Of Procedure Performed (e.g., Resection, Transfusion, Fluoroscopy) The Other Characters Give Additional Information Such as The Body Part and Approach In ICD-10-PCS, the Term Procedure Refers to The Complete Specification of the Seven (7) Characters Page 2-1 of 3 (Organization/Format)

5 2.1 ICD-10-PCS Format (CMS, Development of ICD-10-PCS) The ICD-10-PCS Is Made Up of Three (3) Separate Parts: 1. Tables Must Be Used In Order to Construct a Complete and Valid Code 2. Index Allows Codes to be Located By an Alphabetic Lookup Entry Refers to a Specific Location in the Tables 3. List of Codes Provides a Comprehensive Listing of All Valid Codes, With a Complete Text Description Accompanying Each Code Tables in ICD-10-PCS (CMS, Development of ICD-10-PCS) Example: Value 027 Specifies 1. Section: (0) Medical and Surgical 2. Body System: (2) Heart and Great Vessels 3. Root Operation: (7) Dilation Row from the Tables specifies the valid combinations of Characters 4 through 7 for the Medical and Surgical Root Operation-Dilation of the Heart and Great Vessels-Body System (027) (0) Medical and Surgical (2) Heart and Great Vessels (7) Dilation (Expanding an Orifice or the Lumen of a Body Part-Tubular) Body Part Approach Device Qualifier 0 Coronary Artery, One Site 1 Coronary Arteries, Two Sites 2 Coronary Arteries, Three Sites 3 Coronary Arteries, Four or More Sites 0 Open 3 Percutaneous 4 Percutaneous Endoscopic 4 Drug-eluting Intraluminal Device D Intraluminal Device T Radioactive Intraluminal Device Z No Device 6 Bifurcation Z No Qualifier Index (CMS, Development of ICD-10-PCS) Allows Codes to Be Located Based on an Alphabetic Lookup Codes May Be Found in the Index Based on the General Type of the Procedure (e.g., Resection, Transfusion, Fluoroscopy) Or a More Commonly Used Term (e.g., Appendectomy) Code for Percutaneous Intraluminal Dilation of the Coronary Arteries with an Intraluminal Device Can Be Found in the Index Under Dilation, or a Synonym of Dilation (e.g., Angioplasty) Page 2-2 of 3 (Organization/Format)

6 Once the Desired Term is Located in the Index Index Specifies the First Three or Four Values of the Code(e.g., 027) Or Directs the User to See Another Term Each Table Also Identifies the First Three Values of the Code (e.g., 027) Based on the First Three Values of the Code Obtained From the Index Corresponding Table Can Be Located Table Is Then Used to Obtain the Complete Code by Specifying the Last Four Values List of Codes (CMS, Development of ICD-10-PCS) Valid Codes are Constructed o Using the First Body Part Value (i.e., One Coronary Artery) o Combined with All the Valid Approaches and Devices and the Value No Qualifier Each Code Has a Text Description That Is Complete and Easy to Read Code Descriptions for Dilation of One Coronary Artery (0270) Z 02700DZ 02700TZ 02700ZZ Z 02703DZ 02703TZ 02703ZZ Z 02704DZ 02704TZ 02704ZZ Dilation of Coronary Artery, One Site with Drug-eluting Intraluminal Device, Open Approach Dilation of Coronary Artery, One Site with Intraluminal Device, Open Approach Dilation of Coronary Artery, One Site with Radioactive Intraluminal Device, Open Approach Dilation, Coronary Artery, One Site, Open Approach Dilation, Coronary Artery, One Site with Drug-eluting Intraluminal Device, Percutaneous Approach Dilation, Coronary Artery, One Site with Intraluminal Device, Percutaneous Approach Dilation, Coronary Artery, One Site with Radioactive Intraluminal Device, Percutaneous Approach Dilation, Coronary Artery, One Site, Percutaneous Approach Dilation, Coronary Artery, One Site with Drug-eluting Intraluminal Device, Percutaneous Endoscopic Approach Dilation, Coronary Artery, One Site with Intraluminal Device, Percutaneous Endoscopic Approach Dilation, Coronary Artery, One Site with Radioactive Intraluminal Device, Percutaneous Endoscopic Approach Dilation, Coronary Artery, One Site, Percutaneous Endoscopic Approach Alphabetic Index and Tables (Karla R Lovaasen) The Seven (7) Characters for Medical and Surgical Procedures Have the Following Meaning: 1. Section 2. Body System 3. Root Operation 4. Body Part 5. Approach 6. Device 7. Qualifier Page 2-3 of 3 (Organization/Format)

7 3 ICD-10-PCS Coding Guidelines (CMS, ICD-10-PCS Official Guidelines for Coding and Reporting-2013) A. Conventions A1 A2 A3 A4 Codes Are Composed of Seven (7) Characters Each Character is an Axis of Classification That Specifies Information About the Procedure Performed Within a Defined Code Range, a Character Specifies the Same Type of Information in That Axis of Classification Example: The 5th Axis of Classification Specifies the Approach in Sections 0-4 and 7-9 of the System One of 34 Possible Values Can Be Assigned to Each Axis of Classification in the Seven (7) Character Code: Numbers 0-9 Alphabet (Except I and O) Number of Unique Values Used in an Axis of Classification Differs as Needed Example: Where the 5th Axis of Classification Specifies the Approach, Seven Different Approach Values Are Currently Used to Specify the Approach Valid Values for an Axis of Classification Can Be Added to as Needed Example: If a Significantly Distinct Type of Device Is Used in a New Procedure, a New Device Value Can Be Added to the System As with Words in Their Context, the Meaning of Any Single Value Is o Combination of Its Axis of Classification o and Any Preceding Values on Which It May Be Dependent Example: The Meaning of a Body Part Value in the Medical and Surgical Section is Always Dependent on the Body System Value o Body Part Value 0 in the Central Nervous Body System Specifies Brain o and the Body Part Value 0 in the Peripheral Nervous Body System Specifies Cervical Plexus Page 3-1 of 26 (Guidelines)

8 A5 A6 A7 A8 A9 As the System is Expanded to Become Increasingly Detailed, Over Time More Values Will Depend on Preceding Values for Their Meaning Example: In the Lower Joints Body System, the Device Value 3 in the Root Operation Insertion Specifies Infusion Device and the Device Value 3 in the Root Operation Replacement Specifies Ceramic Synthetic Substitute The Purpose of the Alphabetic Index is to Locate the Appropriate Table That Contains All Information Necessary to Construct a Procedure Code PCS Tables Should ALWAYS Be Consulted to Find the Most Appropriate Valid Code It is NOT Required to Consult the Index First Before Proceeding to the Tables to Complete the Code Valid Code May Be Chosen Directly From the Tables All Seven (7) Characters MUST Be Specified to Be a Valid Code If Documentation Is Incomplete for Coding Purposes o Query Physician Within a PCS Table, Valid Codes Include All Combinations of Choices in Characters 4-7 Contained in the Same Row of the Table In Example Below, 0JHT3VZ Is a Valid Code, and 0JHW3VZ Is NOT a Valid Code Section: Body System: Operation: 0 Medical and Surgical J Subcutaneous Tissue and Fascia H Insertion: Putting in Nonbiological Appliance That Monitors, Assists, Performs, or Prevents a Physiological Function but Does NOT Physically Take the Place of a Body Part Body Part Approach Device Qualifier S Subcutaneous Tissue and Fascia, Head and Neck V Subcutaneous Tissue and Fascia, Upper Extremity W Subcutaneous Tissue and Fascia, Lower Extremity 0 Open 3 Percutaneous 1 Radioactive Element 3 Infusion Device Z No Qualifier T Subcutaneous Tissue and Fascia, Trunk 0 Open 3 Percutaneous 1 Radioactive Element 3 Infusion Device Z No Qualifier Page 3-2 of 26 (Guidelines)

9 V Infusion Pump A10 A11 And When Used in a Code Description, Means And/Or Example: Lower Arm and Wrist Muscle Means Lower Arm And/Or Wrist Muscle Many of the Terms Used to Construct PCS Codes Are Defined Within the System It Is the Coder s Responsibility to Determine What the Documentation in the Medical Record Equates to in the PCS Definitions Physician is NOT Expected to Use the Terms Used in PCS Code Descriptions, NOR is the Coder Required to Query the Physician When the Correlation Between the Documentation and the Defined PCS Terms is Clear Example: When the Physician Documents Partial Resection the Coder Can Independently Correlate Partial Resection to the Root Operation Excision Without Querying the Physician for Clarification 3.2 B. (0) Medical and Surgical Section Guidelines (Section 0) (0) B2. Body System (Medical and Surgical Section 0) B2.1 General Guidelines-Body System (Medical and Surgical Section 0) B2.1a B2.1b Procedure Codes in the Anatomical Regions, General-Body System Should ONLY Be Used When the Procedure is Performed on an Anatomical Region Rather Than a Specific Body Part (e.g., Root Operations-Control and Detachment, Drainage of a Body Cavity) Or on the Rare Occasion When No Information Is Available to Support Assignment of a Code to a Specific Body Part Example: Control of Postoperative Hemorrhage is Coded to the Root Operation Control Found in the Anatomical Regions, General-Body System Where the General Body Part Values Upper and Lower are Provided as an Option in the Page 3-3 of 26 (Guidelines)

10 o Body Systems Above Diaphragm Upper Arteries Upper Veins Muscles and Tendons Below Diaphragm Lower Arteries Lower Veins Muscles and Tendons Example: Vein Body Parts Above the Diaphragm Are Found in the Upper Veins-Body System; Vein Body Parts Below the Diaphragm Are Found in the Lower Veins-Body System B3. Root Operation (Medical and Surgical Section 0) B3.1 General Guidelines-Root Operation (Medical and Surgical Section 0) B3.1a B3.1b In Order to Determine the Appropriate Root Operation, the Full Definition of the Root Operation as Contained in the PCS Tables Must Be Applied Components of a Procedure Specified in the Root Operation Definition and Explanation Are NOT Coded Separately Procedural Steps Necessary to Reach the Operative Site and Close the Operative Site, Including Anastomosis of a Tubular Body Part, NOT Coded Separately Example: Resection of a Joint as Part of a Joint Replacement Procedure is Included in the Root Operation Definition of Replacement and is NOT Coded Separately Laparotomy Performed to Reach the Site of an Open Liver Biopsy is NOT Coded Separately In a Resection of Sigmoid Colon with Anastomosis of Descending Colon to Rectum, the Anastomosis Is NOT Coded Separately B3.2 Multiple Procedures-Root Operation (Medical and Surgical Section 0) B3.2 During the Same Operative Episode, Multiple Procedures Are Coded if: a. Same Root Operation is Performed on Different Body Parts as Defined by Distinct Values of the Body Part Character Page 3-4 of 26 (Guidelines)

11 Example: Diagnostic Excision of Liver and Pancreas Are Coded Separately b. Same Root Operation is Repeated at Different Body Sites That are Included in the Same Body Part Value Example: Excision of the Sartorius Muscle and Excision of the Gracilis Muscle are Both Included in the Upper Leg Muscle Body Part Value, and Multiple Procedures are Coded c. Multiple Root Operations with Distinct Objectives are Performed on the Same Body Part Example: Destruction of Sigmoid Lesion and Bypass of Sigmoid Colon are Coded Separately d. Intended Root Operation is Attempted Using One Approach, but Is Converted to a Different Approach Example: Laparoscopic Cholecystectomy Converted to an Open Cholecystectomy is Coded as Percutaneous Endoscopic Inspection and Open Resection B3.3 Discontinued Procedures-Root Operation (Medical and Surgical Section 0) If the Intended Procedure is Discontinued, Code the Procedure to the Root Operation Performed If a Procedure is Discontinued Before Any Other Root Operation is Performed, Code the Root Operation-Inspection of the Body Part or Anatomical Region Inspected Example: A Planned Aortic Valve Replacement Procedure is Discontinued After the Initial Thoracotomy and Before Any Incision Is Made in the Heart Muscle, When the Patient Becomes Hemodynamically Unstable This Procedure Is Coded as an Open Inspection of the Mediastinum B3.4 Biopsy Followed by More Definitive Treatment-Root Operation (Medical and Surgical Section 0) If a Diagnostic Excision, Extraction, or Drainage Procedure (Biopsy) is Followed by a More Definitive Procedure, Such as Destruction, Excision or Resection at the Same Procedure Site, Both the Biopsy and the More Definitive Treatment Are Coded Example: Biopsy of Breast Followed by Partial Mastectomy at the Same Procedure Site, Both the Biopsy and the Partial Mastectomy Procedure Are Coded B3.5 Overlapping Body Layers-Root Operation (Medical and Surgical Section 0) If the Root Operations Excision, Repair or Inspection Are Performed on Overlapping Layers of the Musculoskeletal System o Body Part Specifying the Deepest Layer Is Coded Example: Excisional Debridement That Includes Skin and Subcutaneous Tissue and Muscle is Coded to the Muscle Body Part B3.6 Bypass Procedures-Root Operation (Medical and Surgical Section 0) B3.6a Bypass Procedures Are Coded by Identifying Page 3-5 of 26 (Guidelines)

(7) Via Natural or Artificial Opening 5. (8) Via Natural or Artificial Opening Endoscopic 6. (F) Open with Percutaneous Endoscopic Assistance 7. (X) External Comprised of Three (3) Components (Approach): 1. Access Location Procedures Performed on an Internal Body Part Access Location Specifies the External Site Through Which the Site of the Procedure is Reached There Are Two (2) General Types of Access Locations: 1. Skin or Mucous Membranes o Can Be Cut or Punctured to Reach the Procedure Site 2. External Orifices Every Approach Value Except External Includes One of These Two Access Locations All Open and Percutaneous Approach Values Use This Access Location Site of a Procedure Can Also Be Reached Through an External Opening External Openings Can Be 1. Natural (e.g., Mouth) 2. Artificial (e.g., Colostomy Stoma) 2. Method For Procedures Performed on an Internal Body Part Method Specifies How the External Access Location is Entered Open Method Specifies Cutting Through the Skin or Mucous Membrane and Any Other Intervening Body Layers Necessary to Expose the Site of the Procedure Instrumental Method Specifies the Entry of Instrumentation Through the Access Location to the Internal Procedure Site Instrumentation Can Be Introduced by 1. Puncture 2. or Minor Incision 3. or Through an External Opening Page 3-20 of 26 (Guidelines)

27 Puncture or Minor Incision Does NOT Constitute an Open Approach Because It Does NOT Expose the Site of the Procedure Approach Can Define Multiple Methods For Example, the Percutaneous Endoscopic Approach Includes Both the Percutaneous Method to Reach the Procedure Site and the Introduction of Instrumentation Into the Body Part to Perform the Procedure 3. Type of Instrumentation Procedures Performed on an Internal Body Part Instrumentation Means That Specialized Equipment is Used to Perform the Procedure Instrumentation is Used in All Internal Approaches Other Than the Basic Open Approach Instrumentation May or May Not Include the Capacity to Visualize the Procedure Site For Example, the Instrumentation Used to Perform a Sigmoidoscopy Permits the Internal Site of the Procedure to Be Visualized, Instrumentation Used to Perform a Needle Biopsy of the Liver Does NOT Term Endoscopic as Used in Approach Values Refers to Instrumentation That Permits a Site to Be Visualized External Approaches Procedures Performed Directly on the Skin or Mucous Membrane Are Identified by the External Approach (e.g., Skin Excision) Procedures Performed Indirectly by the Application of External Force Are Also Identified by the External Approach (e.g., Closed Reduction of Fracture) Approach Definition (0) Open Cutting Through the Skin or Mucous Membrane and Any Other Body Layers Necessary to Expose the Site of the Procedure (3) Percutaneous Entry, by Puncture or Minor Incision, of Instrumentation Through the Skin or Mucous Membrane and/or Any Other Body Layers Necessary to Reach the Site of the Procedure (Pertains to any medical procedure where access to inner organs or other tissue is done via needle-puncture of the skin, rather than by using an Open approach where inner organs or tissue are exposed) (4) Percutaneous Endoscopic Entry, by Puncture or Minor Incision, of Instrumentation Through the Skin or Mucous Membrane and/or Any Other Body Layers Necessary to Reach and Visualize the Site of the Procedure (7) Via Natural or Artificial Opening Entry of Instrumentation Through a Natural or Artificial External Opening to Reach the Site of the Procedure (8) Via Natural or Artificial Opening Endoscopic Entry of Instrumentation Through a Natural or Artificial External Opening to Reach and Visualize the Site of the Procedure (F) Via Natural or Artificial Opening Endoscopic Entry of Instrumentation Through a Natural or Artificial External Opening to Reach and Visualize the Site of the Procedure, and Entry, Page 3-21 of 26 (Guidelines)

Device-Medical and Surgical Section Four (4) General Types of Devices 1. Biological or Synthetic Material that Takes Place of All or Portion of Body Type (e.g., Skin Graft, Joint Prosthesis) 2. Biological or Synthetic Material that Assists or Prevents Physiological Function (e.g., IUD) 3. Therapeutic Material NOT Absorbed by, Eliminated by, or Incorporated into Body Part (e.g., Radioactive Implant) 4. Mechanical or Electronic Appliances Used to Assist, Monitor, Take Place of, or Prevent Physiological Function (e.g., Cardiac Pacemaker, Orthopedic Pin) All Devices CAN Be Removed Some Devices Cannot Be Removed Without Putting in Another Non-Biological Appliance or Body Part Substitute Specific Device Values May Be Coded with Root Operations Alteration Bypass Creation Dilation Drainage Fusion Occlusion Reposition Restriction Specific Device Values Must Be Coded with the Root Operations Change Insertion Removal Replacement Page 3-22 of 26 (Guidelines)

29 Revision Instruments Used to Visualize the Procedure Site are NOT Specified in the Device Value This Information Is Specified in the Approach Value If the Objective of the Procedure is to Put in the Device Root Operation-Insertion If the Device is Put in to Meet an Objective Other Than Insertion Root Operation Defining the Underlying Objective of the Procedure is Used, with the Device Specified in the Device Character For Example, if a Procedure to Replace the Hip Joint is Performed, the Root Operation-Replacement is Coded and the Prosthetic Device is Specified in the Device Character Materials Incidental to a Procedure Such as Clips, Ligatures and Sutures NOT Specified in the Device Character Because New Devices Can Be Developed Other Device is Provided as a Temporary Option for Use Until a Specific Device Value is Added to the System 7.

Guideline A9 states that valid codes within the table include all combinations of choices contained in the same row of the table. 3. False. Guideline B3.1b states procedures to close an operative site, including anastomosis of a tubular body part, are not coded separately. 4. False. Guideline B3.2 states that if the intended root operation is attempted by one approach but is converted to another, code both the discontinued procedure to the root operation performed and the definitive procedure. 5. False. Guideline B3.3 states that when a procedure is discontinued before any root operation is performed, report as Inspection of the body part or anatomical region inspected. 6. True. Guideline B3.4 states that both the biopsy and the definitive treatment are coded. 7. True. Guideline B3.5 states that for the root operations Excision, Repair, and Inspection with overlapping layers of the musculoskeletal system, only the body part identifying the deepest layer is coded. 8. False. Guideline B3.7 directs coders to report the root operation Control for successful control of postprocedural bleeding when it does not require any of the root operations of Bypass, Detachment, Excision, Extraction, Reposition, Replacement, or Resection. 9. True. Guideline B3.2.c states that when multiple root operations with distinct objectives are performed on the same body part, each is coded. 10. True. Guideline B3.11c states to code both the Inspection and the other procedure when each is performed by different approaches on the same body part. Page 4-1 of 2 (Appendix)
