This is a request for information on the use of the following anaesthesia related concepts:

67902001 |Anesthesia for a normal healthy patient (procedure)|
23102000 |Anesthesia for a patient with mild systemic disease (procedure)|
22211001 |Anesthesia for a patient with severe systemic disease (procedure)|
112989003 |Anesthesia for a moribund patient requiring operation (procedure)|
71191009 |Anesthesia for a patient with severe systemic disease, life threatening (procedure)|

In order for us to decide whether we should reach out to the ASA it would be helpful if you could answer the following questions:

1. Is the ASA Physical Status Classification System a nationally accepted classification which is in current widespread use in:

       b. Internationally
2. Are the SNOMED CT concepts identified above widely used in:


       a. The US


       b. Internationally

I would be grateful for your views.
Kind regards
