It would depend on the mushroom.

969 or 977 could be appropriate.

I have no idea what you mean by noxious. I assumed you meant toxic, but you could have meant psychoactive, or other.

Medication practices. Should written policies be developed for abbreviation usage? If yes, what should the policies contain? If no, explain.

To find the number of codes needed to correctly code accidental poisoning by consuming noxious mushrooms, you will need to consult a specific coding system. In this case, I will assume you are referring to medical coding and the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM).

To find the correct code, you can use various resources, including online websites. Here are the steps to find the answer:

1. Open a web browser and search for "ICD-10-CM codes online" or visit the official website for ICD-10 codes, such as the Centers for Disease Control and Prevention (CDC) website.

2. Once you are on a reliable ICD-10-CM website, you can use the search feature provided. Enter relevant keywords like "accidental poisoning" or "noxious mushrooms" to generate a list of related codes.

3. Scan through the search results and look for the specific code that best matches the situation you are asking about. It may be under the category of "Accidental poisoning by ingestion of noxious substances."

4. Each code in the ICD-10-CM system is unique and represents a specific condition. The code you find will provide the necessary information to accurately identify and code accidental poisoning by consuming noxious mushrooms.

Remember, it's essential to use official coding resources and guidelines to ensure the accuracy of the code. Additionally, consulting with a certified medical coder or healthcare professional may be helpful in correctly interpreting and applying the codes.
