alphabetical index
a—>z of dx
tabulan index***
codes in alphamerical order
Main Goal of Coding
coding to the highest level of specificity
How many numbers are in an ICD-10-CM code
7 characters
IMPORTANT codes to know PART ONE.
The letter U
new conditions/diseases
For example: COVID
IMPORTANT CODES TO KNOW PART TWO.
The letter Z
■ prophylactic/preventative care (ON RMA)
■ Z codes is when a patient isn’t sick but the code still needs to have
a letter to get billed.
Steps in ICD-10-CM Coding
○ Step 1: determine the correct diagnosis
○ Step 2: use the main term to look up the diagnosis in the alphabetic index
○ Step 3: look up the “see” term in the alphabetic index
○ Step 4: review essential modifiers under the main term
○ Step 5: choose correct essential modifier based on diagnosis
○ Step 6: look up code in the Tabular List (double-check codes)
A 3-7 more number after the category is considered the diagnosis in more detail.
○ Ex: R12.1234
U codes***
new conditions/diseases
Z codes
prophylactic preventative
Code Hiv
this indicates only the virus is present
NOS***
the diagnostic statement does not contain any more specific wording
abstract***
to collect important information from the health record
carcinoma

carcinoma in situ***
is define as situated
when your finding a code
the letters should be 3 no more than 7
How many different type of coding systems are there?
3.
Code for postpartum
Z39. 2
Codes begin in the of the book
Alphabetical index/section
Codes end in the

Epidemiological
idea. the study of the distribution and determinants of health-related states or events in specified populations
2 Sections in the ICD-10-CM book
○ Alphabetic Index (an A-Z list of diagnoses)

○ Tabular List (a list of the codes in numerical order)
■ Codes to diagnosis
Diagnostic Coding*****
○ Purpose: to prove medical necessity so that insurance companies can be
reimbursed.
