Purpose

1. This WS is designed to create approval on entity, which aggregate other entities (episode_of_care, diagnostic_report, care_plan), OR forbidden group OR diagnoses group, OR on service_request including it’s permitted_resources OR on cancel for encounter, specimen and procedure.

2. Approvals are processed in the async way

3. Only authenticated and authorized employees with appropriate scope can create approval.

Specification

1. API Create Approval

Authorize

1. Verify the validity of access token

   1. in case of error - return 401 (“Invalid access token”) in case of validation fails

2. Verify that token is not expired

   1. in case of error - return 401 (“Invalid access token”)

3. Check user scopes in order to perform this action (scope = 'approval:create ')

   1. return 403 (“Your scope does not allow to access this resource. Missing allowances: approval:create ”) in case of invalid scope(s)

Validation of related entities

Validate user

1. Granted_to.employee_id should be active

   1. in case of error - return 422 “Should be active“

2. If resource from granted_to != 'legal_entity':

   1. Check if employee from the same legal entity as user:

      1. client_id from token should be linked with employee_id from granted_to object.

         1. in case of error - return 422 “Employee <employee_id> doesn't belong to your legal entity“

Validate person authentication_method

1. If resource = care_plan & care_plans.terms_of_service = ‘INPATIENT'&granted_to.employees.legal_entity_id = care_plans.managing_organization:

   1. skip validation of person authentication_method

   2. set approvals.urgent = null

2. In other cases:

   1. Check patient_id:

      1. if belongs to person, then GET auth_method from MPI using {patient_id}

         1. If it's OTP:

            1. send SMS to the auth_phone via otpч_verification service POST /verifications

            2. save authentication_method_current.type and number to DB

            3. return authentication_method_current.type = OTP

         2. If it is offline

            1. save authentication_method_current.type and number to DB

            2. return  authentication_method_current.type = offline

         3.  if it is null:

            1. return error 409 (Person does not have active authentication method)

      2. if belongs to preperson:

         1. set approval urgent = null

Validate authorize_with

The patient can pass the id of his auth_method which he wants to confirm the approval. The necessary auth method can be found by making Get person's auth methods

1. validate auth_method.id is UUID

   1. in case error return 422

2. search auth method in MPI.person_authentication_method

   1. in case error return 422, "such authentication method doesn't exist"

3. search auth method of this patient where  MPI.person_authentication_method.person_id = $.patient.id

   1. in case error return 422, "such authentication method does not belong to this person"

4. validate if auth_method.type = NA

   1. error return 422, "Сannot be confirmed by a method with type= NA. Use a different method."

5. validate that this method is active ( authentication_method.ended_at > now() and is_active = true)

This field is optional and set in new field authorize_with and save type and phone_number in approvals.urgent.authentication_method_current.

If approval doesn't have this field, then choose that method which is returned from mpi as person's default method.

Service logic

1. Set is_verified value to:

   1. false if patient is person.

   2. true if patient is preperson.

2. All the approvals where is_verified = false should be deleted 12 hours after creation - env. configuration parameter

3. All approvals depends on value of granted_resources has its own expires_at config parameter - env. configuration parameter

4. Approvals with child_resources will be created ON entity which is context of this child_resources

5. For approvals on child_resource with resource and on service_request:

   1. set child resource to block reason

   2. set service_request to block reason

6. Check type of authentication_method for patient:

   1. If type = 'OTP' send SMS type of granted_to & type of entity in granted_resources:
