T49.4X2S is a billable diagnosis code used to specify a medical diagnosis of poisoning by keratolytics, keratoplastics, and other hair treatment drugs and preparations, intentional self-harm, sequela. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
T49.4X2S is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like poisoning by keratolytics keratoplastics and other hair treatment drugs and preparations intentional self-harm. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Dithranol overdose
- Intentional dithranol overdose
- Intentional hair treatment poisoning
- Poisoning by hair treatment drug AND/OR preparation
Clinical Classification

Clinical Information
Allantoin
a urea hydantoin that is found in urine and plants and is used in dermatological preparations.Anthralin
an anthracene derivative that disrupts mitochondria function and structure and is used for the treatment of dermatoses, especially psoriasis. it may cause folliculitis.Capsaicin
an alkylamide found in capsicum that acts at trpv cation channels.Capsicum
a plant genus of the family solanaceae. the hot peppers yield capsaicin, which activates vanilloid receptors. several varieties have sweet or pungent edible fruits that are used as vegetables when fresh and spices when the pods are dried.Anacardic Acids
a group of 6-alkyl salicylic acids that are found in anacardium and known for causing contact dermatitis.Salicylates
the salts or esters of salicylic acids, or salicylate esters of an organic acid. some of these have analgesic, antipyretic, and anti-inflammatory activities by inhibiting prostaglandin synthesis.Salicylic Acid
a compound obtained from the bark of the white willow and wintergreen leaves. it has bacteriostatic, fungicidal, and keratolytic actions.
Coding Guidelines
When coding a poisoning or reaction to the improper use of a medication (e.g., overdose, wrong substance given or taken in error, wrong route of administration), first assign the appropriate code from categories T36-T50. The poisoning codes have an associated intent as their 5th or 6th character (accidental, intentional self-harm, assault and undetermined. If the intent of the poisoning is unknown or unspecified, code the intent as accidental intent. The undetermined intent is only for use if the documentation in the record specifies that the intent cannot be determined. Use additional code(s) for all manifestations of poisonings.
The appropriate 7th character is to be added to each code from block Poisoning by, adverse effect of and underdosing of topical agents primarily affecting skin and mucous membrane and by ophthalmological, otorhinorlaryngological and dental drugs (T49). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
Present on Admission (POA)
T49.4X2S is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.
CMS POA Indicator Options and Definitions
POA Indicator | Reason for Code | CMS will pay the CC/MCC DRG? |
---|---|---|
Y | Diagnosis was present at time of inpatient admission. | YES |
N | Diagnosis was not present at time of inpatient admission. | NO |
U | Documentation insufficient to determine if the condition was present at the time of inpatient admission. | NO |
W | Clinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission. | YES |
1 | Unreported/Not used - Exempt from POA reporting. | NO |
Convert T49.4X2S to ICD-9-CM
- ICD-9-CM Code: 909.0 - Late eff drug poisoning
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: E959 - Late eff of self-injury
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 T49.4X2 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.

Patient Education
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.

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.
