2022 ICD-10-CM Code T52.2X4A
Toxic effect of homologues of benzene, undetermined, initial encounter
Code Classification
T52.2X4A is a billable diagnosis code used to specify a medical diagnosis of toxic effect of homologues of benzene, undetermined, initial encounter. The code T52.2X4A is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
T52.2X4A 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 homologues of benzene undetermined. 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.
Coding Guidelines
The appropriate 7th character is to be added to each code from block Toxic effect of organic solvents (T52). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code T52.2X4A is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
MS-DRG | MS-DRG Title | MCD | Relative Weight |
---|---|---|---|
917 | POISONING AND TOXIC EFFECTS OF DRUGS WITH MCC | 21 | 1.4775 |
918 | POISONING AND TOXIC EFFECTS OF DRUGS WITHOUT MCC | 21 | 0.7911 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Table of Drugs and Chemicals
The parent code T52.2X4 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 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.

Information for Patients
Poisoning
A poison is any substance that is harmful to your body. You might swallow it, inhale it, inject it, or absorb it through your skin. Any substance can be poisonous if too much is taken. Poisons can include
- Prescription or over-the-counter medicines taken in doses that are too high
- Overdoses of illegal drugs
- Carbon monoxide from gas appliances
- Household products, such as laundry powder or furniture polish
- Pesticides
- Indoor or outdoor plants
- Metals such as lead and mercury
The effects of poisoning range from short-term illness to brain damage, coma, and death. To prevent poisoning it is important to use and store products exactly as their labels say. Keep dangerous products where children can't get to them. Treatment for poisoning depends on the type of poison. If you suspect someone has been poisoned, call your local poison control center at 1-800-222-1222 right away.
