Its FHIR counterpart is the preAuthRef element in the ClaimResponse. Cross-system integrity of this reference (no truncation, consistent formatting, survives platform migrations) is unglamorous and essential: a lost linkage breaks claims matching and turns follow-up requests into AAA "authorization number not found" rejections.
