# ICD 10 integration

# Description :

This document contains information how the ICD code will be saved in Database and how to API to fetch all the ICD codes.

# Ways to store data :

ICD codes has only three values : code, short description, long description.
We can store the data either in a JSON file or in a Table in database with above three columns.
We are known to a fact that all the records at any given point of time will be there at client end.
So client needs to fetch all the records at once, during 1st time sync.
For above memtioned points, both JSON file or table in Database will work fine.
But if in future, searching and quering is done at server end, then I would recommend it to store in database as searching will be fast at database rather than a JSON file.

# 1. Fetch the ICD 10 codes

GET : /codes/icd

# Response body

Response will have all the records.

{
 "status" : 1,
 "message" : "data fetched",
 "data" : [
    {
      "code" : "A000",
      "shortDescription" : "Cholera due to Vibrio cholerae 01, biovar cholerae",
      "longDescription" : "Cholera due to Vibrio cholerae 01, biovar cholerae"
    }
  ]
}
