Delepoment of the ICD-10-CM
The ICD-10-CM is the classification system that will be used to identify illness (morbidity) and death (mortality) when it replaces ICD-9-CM on October 1, 2014.
The Technical Advisory Panel was established by NCHS to provide input during the development of the 10th revision of I-10.
- Which organization in the United States is responsible for developing the disease classification system, entitled I-10?
The I-10 version released in January 2010 is valid for coding purposes, if your computer system has been updated.
True or False
Improvements in the ICD-10 are:
- Addition of information relevant to ambulatory and managed care encounters
- Expansion of injury codes
- Extensive expansion of the injury codes allows for greater specificity.
- Creation of combination diagnosis/symptom codes to reduce the number of codes needed to fully describe a condition
- The addition of a sixth character
- The incorporation of common fourth- and fifth-digit subclassifications
- Updating and greater specificity of diabetes mellitus codes
- Facilitation of providing greater specificity when assigning codes
No Map Flag
No Map means that there is no similar code from one coding system to the other. When this occurs, there will be a 1 as the second digit in Flag 2. For example, the I-10 code, T36.6X6A, Poisoning by, adverse effect of and underdosing of rifampicins, initial encounter, has no match in I-9. In the I-9 column, "NoDx" appears and there is a 1 in the Flag 2 position.
- Approximate, Flag 0. The Approximate, Flag 0, means there is a direct match between the two coding systems, and the GEMs file directs the coder to a single entry.
- Approximate, Flag 1. The Approximate Flag 1 identifies those times when more than one code in the I-10 is available to replace an I-9 code.
, Flag 3 (third digit in the flag), contains a 1 when a code from the source system must be linked to more than one code in the target system to be valid. For example, in the I-10 system, R65.21, Severe sepsis with septic shock, would require two I-9 codes (995.92, Severe sepsis, and 785.52, Septic shock) to fully report. The I-10 GEMs file displays this requirement with a 1 in the third field.
The number of chapters in I-10 is ____.
The GEMs flag that indicates an exact match between I-10 and I-9 is:
- 1. Flage 0
- 2. Flage 1
- 3. Flage 2
- 4. Flage 3
Excludes 1 and Excludes 2
- The I-10 has two types of Excludes notes. Each note has a different meaning.
- Excludes1. An Excludes1 note is a pure excludes. It means "NOT CODED HERE!" and indicates that the code excluded should not be assigned at the same time as the code above the Excludes1 note.
- Excludes2. An Excludes2 note represents "Not included here." An Excludes2 note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the Excludes2 code together.
Code First/Use Additional Code
Certain conditions have both an underlying etiology and multiple body system manifestations. The I-10 has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "Use additional code" note at the etiology
code, and a "Code first" note at the manifestation
A "Code also" note instructs that two codes may be required to fully describe a condition. Sequencing of the two codes is dependent on the severity of the conditions and the reason for the encounter.
7th Characters and Placeholder X
For codes less than 6 characters that require a 7th character, a placeholder X should be assigned for all characters less than 6.
The word "Includes" appears under certain categories to further define or give examples of the content of the category.
Publishers may enhance their I-10s with notations and symbols that are not part of the official version of the coding system.
The phrase "in diseases classified elsewhere" indicates that the code is:
- a. an underlying etiology.
- b. a late effect.
- c. a manifestation.
I-10 codes are alphanumeric:
A code that reports more than one diagnosis with one code is a ________ code.
- a. multiple
- b. compound
- c. complex
- d. combination
The expansion of the injury codes in the I-10 has been done with ___ codes.
- a sport
- b ambulatory
- c activity
- d dynamic
The acronym used in the United States for the I-10 system that reports inpatient procedures is the ______.
- a PDQ
- b PCS
- c PHI
- d none of the above
I-10 was issued in 1993 by ____.
When implemeted, the United State will be the first nation to convert to the I-10.
I-10 is indexed in a similar manner to ICD-9-cm.
Like I-9, I-10 contains 17 chapters.
The mapping files that crosswalk I-9 to I-10 and I-10 to I-9 are known as _________.
