BAR^P02 — Purge Patient Accounts

Complete purge request for one or several patient accounts on the billing side (administrative HIS to Billing module). Distinct from ADT^A29 which purges the identity in the clinical HIS: P02 only touches the financial dimension.

Purpose

P02 instructs the Billing/financial system to purge one or more patient accounts. Typical cases: post-archival accounting closure, GDPR Article 17 (right to erasure), periodic purge of statute-expired records (10 years in France for the legal retention duration of patient post-care records).

Segment structure

Structure BAR_P02: MSH, [SFT], { EVN, PID, [PD1], [PV1], [DB1] } (1..* groups).

• EVN-1 — Event Type Code: P02.
• EVN-2 — Recorded Date/Time.
• EVN-5 — Operator ID (technical account that triggered the purge — GDPR audit).
• PV1-19 — Visit Number / Account Number (account to purge).
• DB1 — Disability Segment (rarely used in P02 — left for consistency with P01).

Real-world example

GDPR / retention period

In France, HAS recommends 20 years of medical record retention (article R1112-7 CSP) and 10 years for financial records (Code de commerce). BAR^P02 is typically triggered by a nightly batch on accounts whose last invoice is older than now - 10 years.

In the UK, the NHS Records Management Code 2023 requires 8 years after the last consultation for adults. In the US, HIPAA varies by state (6 years typical for CMS-mandated records).

Common errors

• Purge with non-zero balance: most Billing systems refuse P02 if the account balance is > 0. Check first.
• Confusion P02 vs A29: P02 = financial, A29 = clinical/identity. For a complete GDPR erasure, send both.
• EVN-5 missing: the originating operator must be traced for GDPR audit compliance (article 30).
• PV1-19 missing: without account number, Billing doesn't know what to purge.
