Why Change?
• ICD-9 had several problems – We have outgrown it – Vague codes – Inability to describe lateral issues such as fractures – We are the last industrialized country to Change – Two decades behind
![Page 3: The ICD -10 Train · • The last regular, annual updates to both ICD -9-CM and ICD-10 code sets were made on October 1, 2011. • On October 1, 2012 and October 1, 2013 limited code](https://reader030.vdocuments.us/reader030/viewer/2022040214/5ec3932e9b0ef221b454d91a/html5/thumbnails/3.jpg)
Why Change?
• Incorporates much greater specificity and clinical information, which results in: – Improved ability to measure health care services – Increased sensitivity when refining grouping and
reimbursement methodologies; – Enhanced ability to conduct public health surveillance; and – Decreased need to include supporting documentation with
claims

Why Change?
• Includes updated medical terminology and classification of diseases;
• Provides codes to allow comparison of mortality and morbidity data; and

Getting Ready
• Anatomy and Physiology • Query Forms • Clinical Documentation
– Clinical providers - get it documented – Coders – understanding what must be
documented to code correctly
![Page 11: The ICD -10 Train · • The last regular, annual updates to both ICD -9-CM and ICD-10 code sets were made on October 1, 2011. • On October 1, 2012 and October 1, 2013 limited code](https://reader030.vdocuments.us/reader030/viewer/2022040214/5ec3932e9b0ef221b454d91a/html5/thumbnails/11.jpg)
Getting Ready
• Start reviewing charts using ICD-10-CM codes. • If you code it once, you will code it a thousand
times – Know your ICD-9-CM codes – Learn your ICD-10-CM codes – Break it up - one code at a time
![Page 12: The ICD -10 Train · • The last regular, annual updates to both ICD -9-CM and ICD-10 code sets were made on October 1, 2011. • On October 1, 2012 and October 1, 2013 limited code](https://reader030.vdocuments.us/reader030/viewer/2022040214/5ec3932e9b0ef221b454d91a/html5/thumbnails/12.jpg)

Coding Conventions (6)

Coding Conventions (7) • Punctuation
– Just like ICD-9-CM – [] Brackets are used in the Tabular List to enclose synonyms,
alternative wording or explanatory phrases. Brackets are used in the Alphabetic Index to identify manifestation codes.
– ()Parentheses are used in both the Alphabetic Index and Tabular List to enclose supplementary words that may be present or absent in the statement of a disease or procedure without affecting the code number to which it is assigned. The terms within the parentheses are referred to as nonessential modifiers.
– : Colons are used in the Tabular List after an incomplete term which needs one or more of the modifiers following the colon to make it assignable to a given category.

Coding Conventions (9)
• Make sure you understand!
• “Other” codes – These Alphabetic Index entries represent specific
disease entities for which no specific code exists so the term is included within an “other” code.
• “Unspecified” codes – Codes titled “unspecified” are for use when the
information in the medical record is insufficient to assign a more specific code.
