T54.2X1A is a billable diagnosis code used to specify a medical diagnosis of toxic effect of corrosive acids and acid-like substances, accidental (unintentional), initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
T54.2X1A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like toxic effect of corrosive acids and acid-like substances accidental (unintentional). According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Clinical Information
Oxalates
derivatives of oxalic acid. included under this heading are a broad variety of acid forms, salts, esters, and amides that are derived from the ethanedioic acid structure.Oxalic Acid
a strong dicarboxylic acid occurring in many plants and vegetables. it is produced in the body by metabolism of glyoxylic acid or ascorbic acid. it is not metabolized but excreted in the urine. it is used as an analytical reagent and general reducing agent.
Coding Guidelines
The appropriate 7th character is to be added to each code from block Toxic effect of corrosive substances (T54). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
Convert T54.2X1A to ICD-9-CM
- ICD-9-CM Code: 983.1 - Toxic effect acids
Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment. - ICD-9-CM Code: E924.1 - Accid-caustic substance
Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.
Table of Drugs and Chemicals
The parent code T54.2X1 of the current diagnosis code is referenced in the Table of Drugs and Chemicals, this table contains a classification of drugs, industrial solvents, corrosive gases, noxious plants, pesticides, and other toxic agents.
According to ICD-10-CM coding guidelines it is advised to do not code directly from the Table of Drugs and Chemicals, instead always refer back to the Tabular List when doing the initial coding. Each substance in the table is assigned a code according to the poisoning classification and external causes of adverse effects. It is important to use as many codes as necessary to specify all reported drugs, medicinal or chemical substances. If the same diagnosis code describes the causative agent for more than one adverse reaction, poisoning, toxic effect or underdosing, utilize the code only once.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
