ICD-10-CM Alphabetic Index

 

Even though the ICD-10 is granular, many diseases/disorders are not listed in tabular list. Many concepts are listed in the Alphabetic Index. This will pose a challenge to ICD-10 coders.

Example:  Mesenteric saponification is listed in the Alphabetic Index, but is not in the Tabular List.

Some of the diseases/disorders listed in ICD-9 Alphabetic Index as nonessential modifiers are listed in ICD-10 Tabular.  Example:  See Cirrhosis-biliary  (cholangiolitic) (cholangitic) (cholestatic) (extrahepatic) (hypertrophic) (intrahepatic) (nonobstructive) (obstructive) (pericholangiolitic) (posthepatic) (primary) (secondary) (xanthomatous)

Primary and secondary biliary cirrhosis are listed as 2 separate codes in iCD-10 Tabular.

ICD-10 Specific codes

   K74.3: Primary biliary cirrhosis

Chronic nonsuppurative destructive cholangitis

  K74.4: Secondary biliary cirrhosis 

Some of the essential modifiers listed in alphabetic index of ICD-9-CM are made to non-essential modifiers in ICD-10-CM

Example: Index entry for Agranulocytosis (see also Neutropenia) 288.09 in ICD-9-CM is linked with seven essential modifiers (chronic, cyclical, due to infection, genetic, infantile, periodic, pernicious), but index entry for Agranulocytosis (chronic) (cyclical) (genetic) (infantile) (periodic) (pernicious) (see also Neutropenia) D70.9 six essential modifiers of ICD-9-CM are made to non-essential modifiers

Some of the non-essential modifiers from ICD-9-CM are made to essential modifiers in ICD-10-CM and some of them are not mentioned at all in ICD-10-CM. What if physician uses the terminology which is abandoned in ICD-10-CM.  How the coder should take decisions while assigning codes in such cases?

 

 

Example:  The index entry of the the term “Aphasia” in ICD-9-CM and ICD-10-CM is as follows:

Aphasia (amnestic) (ataxic) (auditory) (Broca's) (choreatic) (classic) (expressive) (global) (ideational) (ideokinetic) (ideomotor) (jargon) (motor) (nominal) (receptive) (semantic) (sensory) (syntactic) (verbal) (visual) (Wernicke's) 784.3

Aphasia (amnestic) (global) (nominal) (semantic) (syntactic) R47.01

If a physician uses diagnostic statements as

ataxic aphasia or

Broca’s aphasia or

Choreatic apahsia or

Classic aphasia or

Expressive aphasia or

Ideational aphasia or

Ideokinetic aphasia or

Ideomotor aphasia or

Jargon aphasia or

Motor aphasia or

Receptive aphasia or

Verbal aphasia or

 

Visual aphasia or
