AMM-2228 Unable to add multiple diagnoses

1. Ticket Details

2. Issue Description

Doctor unable to search for a second diagnosis after adding the first one for a beneficiary.

3. Root Cause Analysis (RCA)

Technique Used: Log/Trace Review

 The onDiagnosisInputKeyup() method in the diagnosis components was passing the .FormArray row index as the pageNo parameter to the SNOMED CT search API.
The API searchDiagnosisBasedOnPageNo(term, pageNo) expects a pagination page number, not a row identifier.

 onDiagnosisInputKeyup(value: string, index: number) {
      this.masterdataService
          .searchDiagnosisBasedOnPageNo(value, index)  // index used as pageNo
          .subscribe((results) => {
              this.suggestedDiagnosisList[index] = results?.data?.sctMaster;
          });
  }

Impact

  - Affected all 4 diagnosis components: General OPD, PNC, NCD Care, NCD Screening
  - Doctors could only add 1 diagnosis per beneficiary via inline search
  - The dialog-based search (via Enter key/directive) was not affected as it manages pagination independently

4. Corrective Actions (Fixes for this instance)

5. Preventive Actions (To prevent recurrence)

6. Verification of Effectiveness

• •    General OPD flow: Login as Doctor, open a beneficiary, add 1st diagnosis via search, 
      click "+" and search for a 2nd diagnosis — verify search results appear for both rows

  •  Multiple rows: Add 3rd, 4th, 5th diagnosis in subsequent rows — verify all rows      
      return search results regardless of row position          

  •  PNC visit: Repeat multi-diagnosis search in PNC visit category — verify results
      appear for all rows                                                                  

  • NCD Care visit: Repeat multi-diagnosis search in NCD Care visit category — verify
      results appear for all rows                                                            

  • NCD Screening visit: Repeat multi-diagnosis search in NCD Screening visit category —
      verify results appear for all row

  •  No regression on 1st row: Verify the first diagnosis row still returns search results
       as before

  •  Save and view: Save the case record with multiple diagnoses and reopen in view mode —
       verify all added diagnoses are displayed correctly  

  • API verification: Check DevTools → Network tab and confirm all search requests send
      pageNo: 0 in the request payload, regardless of which row the search is triggered from
