DG1 segment

The DG1 segment contains patient diagnosis information of various types, for example, admitting, primary, etc. The DG1 segment is used to send multiple diagnoses (for example, for medical records encoding). It is also used when the FT1-19 - Diagnosis Code - FT1 does not provide sufficient information for a billing system. This diagnosis coding should be distinguished from the clinical problem segment used by caregivers to manage the patient (see Chapter 12, Patient Care). Coding methodologies are also defined.

required optional kept for older systems, still counted

Count the pipes to find a field, and count the empty ones too: an empty field still holds its place. Leave out the separator before DG1-6 and its value arrives as DG1-5, so the receiver stores Diagnosis Type as Diagnosis Date/Time.

This page carries the DG1 field table as published and nothing beyond it. The field notes, vendor behaviour, FHIR mapping and parsing guidance that thePID page has are still to be written for DG1.
