T57.8X4D is a billable diagnosis code used to specify a medical diagnosis of toxic effect of other specified inorganic substances, undetermined, subsequent 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. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
T57.8X4D 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 other specified inorganic substances undetermined. 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 Information
Asbestos
asbestos. fibrous incombustible mineral composed of magnesium and calcium silicates with or without other elements. it is relatively inert chemically and used in thermal insulation and fireproofing. inhalation of dust causes asbestosis and later lung and gastrointestinal neoplasms.Asbestos, Amosite
asbestos, grunerite. a monoclinic amphibole form of asbestos having long fibers and a high iron content. it is used in insulation. (mcgraw-hill dictionary of scientific and technical terms, 4th ed)Asbestos, Amphibole
a class of asbestos that includes silicates of magnesium, iron, calcium, and sodium. the fibers are generally brittle and cannot be spun, but are more resistant to chemicals and heat than asbestos, serpentine. (from hawley's condensed chemical dictionary, 11th ed)Asbestos, Crocidolite
a lavender, acid-resistant asbestos.Asbestos, Serpentine
a type of asbestos that occurs in nature as the dihydrate of magnesium silicate. it exists in two forms: antigorite, a plated variety, and chrysotile, a fibrous variety. the latter makes up 95% of all asbestos products. (from merck index, 11th ed, p.893)Asbestosis
a form of pneumoconiosis caused by inhalation of asbestos fibers which elicit potent inflammatory responses in the parenchyma of the lung. the disease is characterized by interstitial fibrosis of the lung, varying from scattered sites to extensive scarring of the alveolar interstitium.
Coding Guidelines
The appropriate 7th character is to be added to each code from block Toxic effect of other inorganic substances (T57). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
Present on Admission (POA)
T57.8X4D 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 T57.8X4D to ICD-9-CM
- ICD-9-CM Code: V58.89 - Other specfied aftercare
Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.
Table of Drugs and Chemicals
The parent code T57.8X4 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.
