Not Valid for Submission
T45.3X4 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of poisoning by enzymes, undetermined. The code is not specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
The ICD-10-CM code T45.3X4 might also be used to specify conditions or terms like penicillinase poisoning of undetermined intent, poisoning by penicillinase, poisoning by streptodornase or streptodornase poisoning of undetermined intent.
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 Primarily systemic and hematological agents, NEC (T45). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
Specific Coding for Poisoning by enzymes, undetermined
Non-specific codes like T45.3X4 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for poisoning by enzymes, undetermined:
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Penicillinase poisoning of undetermined intent
- Poisoning by penicillinase
- Poisoning by streptodornase
- Streptodornase poisoning of undetermined intent
Table of Drugs and Chemicals
The code T45.3X4 is included 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.
