Alphabetic Index and Tabular List Memo
Good afternoon team, the reason for this email is to bring everyone up to date on the Alphabetic
Index and the tabular list and some of the obstacles that may arise when using it.
When coding a patient encounter, First, select the diagnosis for the visit. This means that you
will need to analyze and abstract the medical report then you will need to find the main reason
for the patient encounter. Why did this patient come to see their physician? Find the diagnosis.
Next, you will refer to the alphabetic index look for your correct code, Finally, the code needs to
be verified in the tabular list by checking the code. Also, there is a need to pay attention to the
cross references, if you see (see also) next to the diagnosis code you would need to cross
reference that diagnosis and look up the term that reflects the information in the index. Be
cautious if the encounter is coded incorrectly it could result in an underpayment that results in a
loss of revenue or it could cause an overpayment of services or even a denial of the claim.
According to "Icd-10 Code"(10/01/2020), ICD-10-CM is divided into the Alphabetic Index, an
alphabetical list of terms and their corresponding code, and the Tabular List, which is a
chronological list of codes divided into chapters based on body system or condition. The
alphabetic index and the tabular list are to designate a medical or diagnosis code for billing.
