A records production almost never arrives complete. Sometimes that's innocent — a department's records sit in a separate system, a fax never made it. Sometimes it isn't. Either way, the gap is the plaintiff's problem to find, because the defense has no incentive to point it out. The skill is reading a production for what isn't there.

Read the Chronology for Holes

The fastest way to find a missing record is to lay the events out in order and look for the breaks in continuity:

Each of these is a thread. Built into a chronology, the gaps stop being invisible — they line up next to the entries that point at them.

The Audit Trail Proves It Existed

The strongest proof that a record is missing is evidence it was there. EHRs log access — who opened, viewed, printed, or exported each part of the chart. If the access log shows a radiology report was viewed and printed during the admission, but that report isn't in the production, the gap is no longer arguable. Federal regulation requires these audit controls (45 CFR § 164.312(b)), certified systems must record auditable events (45 CFR § 170.315(d)(2)), and the content standard is ASTM E2147-18. The audit trail is discoverable — see Vargas v. Lee, 170 A.D.3d 1073 (N.Y. App. Div. 2d Dep't 2019).

Prove the record existed — request the access log

Our free EHR Audit-Trail Discovery Request generator builds a request for the access and audit logs that show what was viewed, printed, or exported — using each EHR's system-specific report name plus the legal hooks. If a document was accessed but never produced, the log is how you prove it.

You Have a Right to the Complete Set

Under HIPAA, a patient (and their authorized representative) has a right of access to the designated record set45 CFR § 164.524, with the set defined at 45 CFR § 164.501. That set is broader than the summary a provider may hand over by default. Requesting "the complete designated record set," by name, closes the easy gap where only part of the chart is produced.

When the Gap Is Deliberate

If a record that demonstrably existed cannot be produced, the question becomes spoliation. Remedies — adverse-inference instructions, sanctions — vary widely by jurisdiction and depend on intent and prejudice, so confirm the standard in your venue. But you cannot make the argument until you've first proven the gap: the chronology shows the hole, and the audit trail shows the record was real.

General information for attorneys, not legal advice. Records-access rights, discovery scope, and spoliation remedies vary by jurisdiction — verify every statute, rule, and case against current authority in your venue.
