T51.0X1D is a billable diagnosis code used to specify a medical diagnosis of toxic effect of ethanol, accidental (unintentional), subsequent encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2025 through September 30, 2026. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

T51.0X1D is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like toxic effect of ethanol accidental (unintentional). According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

CCSR Code: INJ060

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

• Ethanolamines

amino alcohols containing the ethanolamine; (-nh2ch2choh) group and its derivatives.

• Phosphatidylethanolamines

derivatives of phosphatidic acids in which the phosphoric acid is bound in ester linkage to an ethanolamine moiety. complete hydrolysis yields 1 mole of glycerol, phosphoric acid and ethanolamine and 2 moles of fatty acids.

• Quetiapine Fumarate

The appropriate 7th character is to be added to each code from block Toxic effect of alcohol (T51). Use the following options for the aplicable episode of care:

• A - initial encounter
• D - subsequent encounter
• S - sequela

T51.0X1D 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: Y

Reason: Diagnosis was present at time of inpatient admission.

CMS Pays CC/MCC DRG? YES

POA Indicator: N

Reason: Diagnosis was not present at time of inpatient admission.

CMS Pays CC/MCC DRG? NO

POA Indicator: U

Reason: Documentation insufficient to determine if the condition was present at the time of inpatient admission.

CMS Pays CC/MCC DRG? NO

POA Indicator: W

Reason: Clinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission.

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

ICD-9-CM: V58.89

Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.

The parent code T51.0X1 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.

Alcohol

Many Americans drink alcohol at least occasionally. The Dietary Guidelines for Americans say that adults of legal drinking age should either not drink or drink in moderation. Drinking less is better for your health than drinking more. Also, there are some people who should not drink at all.

If you are going to drink, it's important to know how alcohol affects you and how much is too much.

How does alcohol affect the body?

Alcohol is a central nervous system depressant. This means that it is a drug that slows down brain activity. It can change your mood, behavior, and self-control. It can cause problems with memory and thinking clearly. Alcohol can also affect your coordination and physical control.

Alcohol also has effects on the other organs in your body. For example, it can raise your blood pressure and heart rate. If you drink too much at once, it could make you throw up.

Why are the effects of alcohol different from person to person?

Alcohol's effects vary from person to person, depending on a variety of factors, including:

• How much you drink
• How often you drink
• Your age
• Your sex
• Your genetics
• Your overall health
• Whether or not you have a family history of alcohol problems

What is moderate drinking?

• For most women, moderate drinking is no more than 1 standard drink a day
• For most men, moderate drinking is no more than 2 standard drinks a day

Even though moderate drinking may be safe for many people, there are still risks. Moderate drinking can raise the risk of death from certain cancers and heart diseases.

What is a standard drink?

In the United States, a standard drink is one that contains about 14 grams of pure alcohol, which is found in:

• 12 ounces of regular beer (5% alcohol content)
• 5 ounces of wine (12% alcohol content)
• 1.5 ounces or a "shot" of distilled spirits or liquor (40% alcohol content)

Who should not drink alcohol?

Some people should not drink alcohol at all, including those who:

• Are in recovery from an alcohol use disorder (AUD)
• Are are unable to control the amount they drink
• Are under age 21
• Are pregnant or trying to become pregnant
• Are taking medicines that can interact with alcohol
• Have medical conditions that get can worse if you drink alcohol
• Are planning on driving
• Will be operating machinery or doing activities that require skill, coordination, and alertness

If you have questions about whether it is safe for you to drink, talk with your health care provider.

What is excessive drinking?

Excessive drinking includes binge drinking and heavy alcohol use:

• Binge drinking is drinking so much at once that your blood alcohol concentration (BAC) level is 0.08% or more:
  • For men, this usually happens after having 5 or more drinks within a few hours.
  • For women, it is usually after about 4 or more drinks within a few hours.
• Heavy alcohol use means:
  • For men, having more than 5 drinks on any day or more than 15 drinks per week.
  • For women, having more than 4 drinks on any day or more than 8 drinks per week.

Binge drinking raises your risk of injuries, car crashes, and alcohol overdose. It also puts you at risk of becoming violent or being the victim of violence.

Heavy alcohol use over a long period of time may cause health problems such as:

• Alcohol use disorder (AUD)
• Liver diseases, including cirrhosis and fatty liver disease
• Heart diseases
• Increased risk of certain cancers
• Increased risk of injuries

Heavy alcohol use can also cause problems at home, at work, and with friends. But treatment can help.
