Pass FDA's refuse-to-accept review on your first try. Six documents covering every reason FDA sends 510(k)s back before substantive review.
Instant download. For QA/RA professionals at Class II device companies.
FDA's refuse-to-accept rate for 510(k) submissions has been rising since 2023. The most common reason isn't a bad device — it's incomplete predicate documentation and thin substantial equivalence analysis. FDA sends the submission back before they even read the technical file.
A single RTA costs 3–6 months of review delay plus repeated submission preparation. It's preventable with the right pre-submission discipline.
Organized in the order you'd use them building a submission.
40+ line items organized by FDA's 2019/2023 RTA criteria. Administrative, device description, predicate documentation, SE comparison, testing, biocompatibility, labeling, software. Red/yellow/green scoring. Run this before you submit.
510(k) database search strategy, product code and classification panel lookup, evaluating intended use match, tech characteristics analysis, predicate decision tree. Includes predicate research worksheet.
All 4 SE argument types FDA accepts — with fill-in-the-blank templates for each. Type A (same everything), Type B (different tech, no new questions), Type C (performance data resolves questions), Type D (split predicate). NSE pitfall guide.
Every required element per 21 CFR 807.87, structured in fill-in-the-blank format. Truthfulness certification, predicate table, submission type, prior history. 7-item mistake guide with specific fixes.
2026 FDA expectations: operating principle depth, component tables, software description requirements, cybersecurity section triggers. Annotated weak vs. strong examples so you know the difference before FDA tells you.
How to request a Q-Sub, MDUFA V timelines, question templates for SE strategy, testing requirements, and IFU scope. How to document and use FDA's response. Full Q-Sub request template included.
An RTA sends you back to day zero on the review timeline. Prevention costs $197. The delay from a single RTA costs months of market access.
The RTA checklist maps directly to FDA's 2024-2025 RTA guidance. The SE templates are structured around how FDA's reviewers actually evaluate submissions.
There are four. Each has a different evidence burden. Using the wrong one is why submissions get NSE'd even when the device is safe and effective.

“I built these templates from 12 years of running a Class II/III medical device manufacturing operation. Every document reflects what FDA investigators actually ask for — not what consultants think they ask for. We use these exact frameworks at AB Medical.”
Joshua Millage, CEO — AB Medical Technologies
“When you've been through enough FDA inspections, you learn what documentation gaps get flagged and which ones slide. These templates close the gaps that matter. We developed them alongside our own QMS buildout and they've held up under audit.”
Rick, Director of Engineering & Regulatory — AB Medical Technologies
It works for first-timers, but it's written for QA/RA professionals who know what a 510(k) is. If you've submitted before and been refused or had extended reviews, this tells you why and how to fix it.
Primary focus is Traditional 510(k)s — the most common type. The cover letter template and RTA checklist note where Abbreviated and Special 510(k)s have different requirements.
Yes. The RTA checklist reflects FDA's 2023 guidance updates. The device description guide addresses current cybersecurity and software documentation requirements. The Q-Sub guide reflects MDUFA V timelines.
No. This is a practitioner reference toolkit. Consult your regulatory counsel for formal legal compliance opinions.
