The medical device file that replaced the DMR

Since February 2, 2026, 21 CFR 820 no longer names a device master record, a design history file, or a device history record. The Quality Management System Regulation replaced the old Quality System Regulation's own structure by incorporating ISO 13485:2016 by reference, and FDA said plainly in the rulemaking that it saw no need to keep naming those three records separately once the standard's own documentation clauses covered the same ground. That's a narrower change than it sounds. The content those three records used to carry didn't disappear — it moved, unevenly, into ISO 13485's own Clause 4.2 and Clause 7, and a quality file that just renames its old DMR folder ‘Medical Device File’ without checking whether the new clause's own list actually matches the old one has done a filing exercise, not a compliance one.

Incorporation by reference, not a rewrite from scratch

The QMSR final rule amends the device current good manufacturing practice requirements of 21 CFR Part 820 by making ISO 13485:2016, Medical devices — Quality management systems — Requirements for regulatory purposes, the core set of requirements for most finished-device manufacturers, in place of the detailed, FDA-specific text the old Quality System Regulation spelled out clause by clause. FDA finalized the rule in early February 2024 and set a two-year transition, making February 2, 2026 the compliance date every manufacturer's own quality system had to meet. A file built against the old QSR's own numbered subparts and never mapped forward onto the incorporated standard's own clause structure is, as of that date, being checked against a regulation whose text it no longer matches.

Three named records become one clause — sized differently

ISO 13485 Clause 4.2.3 requires one or more medical device files per device type or family, covering the device's general description and intended purpose, its labeling and instructions for use, its specifications, its manufacturing, packaging, storage, handling and distribution procedures, its measuring and monitoring procedures, and its installation and servicing requirements where applicable. That list overlaps substantially with what old 820.181 required of a device master record — but a DMR was never the only record the old QSR named. Design history file content, under old 820.30(j), and device history record content, under old 820.184, don't map onto Clause 4.2.3 at all; that material now sits inside Clause 7.3's design-and-development records and Clause 7.5's production records instead. A quality file that collapses all three old records into one folder renamed ‘Medical Device File’ has followed the DMR's own content across the rename correctly and left the DHF's and DHR's content with no clause of its own to answer to.

What FDA kept as its own, on top of the standard

ISO 13485 doesn't cover several things the QMSR still requires directly, layered on top of the incorporated standard rather than replacing any part of it: unique device identification under Part 830, recorded for each device or batch beyond what the standard's own clauses on labeling and traceability already ask for; complaint handling tied to medical device reporting under Part 803; and corrections and removals reporting under Part 806. None of these three obligations traces back to a clause number in ISO 13485 at all — a quality manual that maps its procedures entirely to the standard's own clause list and treats that mapping as complete has skipped the requirements the QMSR kept as distinctly its own.

The inspection program moved on the same date

The shift wasn't limited to the regulation's own text. FDA's inspection process changed alongside it: as of February 2, 2026, the agency retired its prior device-manufacturer inspection compliance program and began inspecting against a new one built around the QMSR's own structure, rather than the QSR subparts an inspector's checklist used to follow. A facility whose internal audit program still walks its own quality system against the old compliance program's structure is rehearsing for an inspection approach FDA has already replaced.

Where this reaches the rest of the file

The clause renumbering underneath a quality system is the same kind of drift a mapped resource has to watch for on any source, not just this one — a citation that was correct against the old QSR and never rechecked against the incorporated standard is exposed exactly the way an outdated standard citation is anywhere else in a technical file. And the same document-control discipline that keeps a document-control SOP current against its own governing procedure is what a quality file needs applied to its own record structure here — not a rename, but a clause-by-clause recheck of what content the new structure actually requires.

A QMSR transition worksheet built around this structure — the DMR content mapped to Clause 4.2.3, the DHF and DHR content mapped separately into Clause 7, and the UDI, complaint, and corrections-and-removals requirements tracked as FDA's own retained additions — is previewed in the launch catalog. If your program's mapping runs differently, the shelf takes that correction directly.
