1 ICD-10 THE BASICS All Rights Reserved Agenda Intro ICD-9 vs. ICD-10 ICD Basics (9 & 10) Understanding ICD 10: the book Assigning a code Interesting nomenclature Coding Tips Examples Summary 1

2 ICD-9 vs. ICD-10 Textbook ICD-9-CM Code Totals: 13,500 Chapters: 17 Primarily Numeric ICD-10-CM Code Totals: 68,000 Chapters: 21 All Alpha-Numeric Similarities: Alphabetical Index & Tabular List PCS & CM Similar Nomenclature ICD-9 vs. ICD-10 Structure ICD-9-CM 3 to 5 characters Primary Numeric Except V & E Codes 4 & 5 afford additional specificity Example: Splinter, foot/toes ICD-10-CM 3 to 7 characters Character 1 alpha Character 2 & 3, numeric Character 3 to 7, alpha/numeric Example: S90.452A Superficial foreign body, left great toe, initial encounter 2

3 ICD Usage Guidelines October 1st Effective Date Identify all diagnoses, symptoms, conditions, problems, complaints, or reason for service or procedure List primary condition first, then current/active issues Utilize max characters Probable, suspected, rule out, or questionable diagnoses should not be coded until the diagnosis is confirmed; code symptoms, signs, conditions, test results, or other reasons for the encounter Chronic diseases: report as many times as the patient receives treatment for the condition Ancillary diagnostic or therapeutic service: List V (ICD-9) or Z (ICD-10) code, as able, as the 2 nd ICD Surgical Service: Code condition for which service is performed or definitive diagnosis if different DO NOT CODE WHAT NO LONGER EXISTS! ICD to CPT Linkage Example 3

4 Basics of the ICD Book: ICD-10 s two volumes Alphabetic Index (Vol. 1) Tabular List (Vol. 2) Procedural Code System (Vol. 3) not needed!! The Alphabetical Index Consists of Alphabetical list of terms Corresponding code Additional sections: Index of Diseases and Injury Index of External Causes of Injury Table of Neoplasms Table of Drugs and Chemicals 4

5 Alpha Index E.g. The Tabular List Structured list of codes Chapters based on body system or condition All in alpha-numerical order Instructional notes and directions Includes Excludes 1 and 2 Status/stage of care (A,D,S) NOTES Placeholders and/or additional digits 5

6 Tabular List Example ICD Code Assignment Steps Start in the Alphabetical Index Follow instructions Subsets See See also Omit codes DO NOT CODE FROM THE INDEX Locate code in the Tabular List Read all the instructional materials Consult and apply any coding guidelines Confirm and assign the code(s) 6

7 ICD Code Assignment E.g. 4. Chalazion, right lower eyelid Start with the Index Main terms: Identify Conditions or Injuries Acute Appendicitis: Look under Appendicitis Stress Fracture: Look under Fracture Sub Terms: Under the main terms Indented to the right Lower case letter Not in bold Find Bronchospasm in your Index 7

8 First step: Identify Main Term Bronchospasm (acute) J98.01 with bronchiolitis, acute J21.9 bronchitis, acute (conditions in J20) see Bronchitis, acute due to external agent see condition, respiratory, acute, due to exercise induced J Categories & Subdivision Characters may be a letter or a number All categories = 3 characters If 3-character category with no subdivision 3-character item IS the full ICD code Subcategories: 4 or 5 characters ICD Codes are 3 to 7 characters Subcategory = each level of subdivision Final level of a subdivision = selected code Codes with 7 th character invalid without 7 th 8

9 Contraception (was V25) Z30: Category Encounter for contraceptive management Z30.4: Subcategory Encounter for surveillance of contraceptives Z30.41 Encounter for surveillance of contraceptive pills Inclusion Term Encounter for repeat prescription for contraceptive pill Default Codes Found in Alphabetical index Code listed next to a main term Default code = Condition most commonly associated with the main term OR Unspecified code for the condition Documented condition without additional detail, assign default code E.g., N80.9 for endometriosis 9

10 Alpha Index Example Alpha Index Example 10

11 Concern about Default Codes Similar to unspecified ICD-9 Unspecified exists in ICD-10 but avoidable Because so many options exist Concern some payers may deny unspecified Too early to know for certain but avoidable As always, code & DOCUMENT what you know Crosswalk Examples 11

12 Multiple Diagnoses One code may capture two diagnoses (E.g. #1) E.g., Flu with digestive issues Other conditions may require two codes (E.g., #2) E.g., Type II diabetic who uses insulin E.g. #1: Influenza with digestive manifestations 12

13 E.g. #2: Type 2 diabetic with diabetic cataract, patient uses insulin regularly Multiple codes, single condition Code first causal conditions when known Assign as principal when causal condition unknown/not applicable Causal condition known, code the condition as the principal or firstlisted diagnosis Multiple codes possible if Sequela Complication codes Obstetric codes, more fully describe condition(s) See specific guidelines for further instruction 13

14 E.g.: Chronic Pain in right knee Combination Code (1 of 2) Used to classify: Two diagnoses, or Diagnosis with associated secondary process (manifestation) Diagnosis with associated complication Identified by Referring to subterm entries in the Alphabetic Index Reading inclusion and exclusion notes in the Tabular List 14

15 Combination Code (2 of 2) Assign only combination code when: Code fully identifies diagnostic conditions involved Alphabetic Index so directs Multiple codes NOT used when Code exists which clearly identifies all of the elements documented in the diagnosis Code lacks necessary specificity describing manifestation or complication, Additional code as a secondary code Combo Code Example (1 of 2) Perforation of tympanic membrane due to chronic suppurative otitis media, right ear (1 of 2) Answer, Part 1: H

16 Combo Code Example (2 of 2) Perforation of tympanic membrane due to chronic suppurative otitis media, right ear (2 of 2) Answer, Part 2: H66.3X1 Final Answer: H66.3X1 & H72.91 Impending/Threatened Condition (1 of 2) If it did occur: Code confirmed diagnosis If it did not occur Reference Alphabetic Index Determine if condition has subentry term for impending or threatened Reference main term entries for impending or threatened 16

17 Impending/Threatened Condition (2 of 2) Sub terms listed, assign given code Sub terms not listed Code existing underlying condition(s) Code not condition described as impending or threatened Impending/Threatened Condition Example 17

18 Acute & Chronic Conditions Patient condition Both acute (sub acute) and chronic Separate subentries in Alphabetic Index Code both with acute (sub acute) code primary Acute & Chronic Example 18

19 Laterality Some codes indicate Left vs. Right No bilateral code, code each L & R code Side not documented = unspecified Laterality Example 1 19

20 Laterality Example 2 Code what you know diagnostic tests Results available? Code results No Results, code symptoms/condition 20

21 Excludes 1 & Excludes 2 Excludes1 REALLY means do not code with main term Excludes2 SHOULD say OK to code also if it exists Excludes 1 & 2 Example 21

22 Place Holder (X) Character Placeholder = character X X used to allow for future expansion E.g., adverse effect and under dosing (T36-T50) Certain ICD-10-CM = 7 characters i.e., 7th character required for all codes within the category Code requires a 7th character < 6 characters, placeholder X needed Place Holder (X) E.g., #1 22

23 Place Holder (X) E.g., #2 Place Holder (X) E.g. #3 23
