Medical record review firms by specialty
Short version: 9 of the 39 firms publish a specialty count, from 150+ (MRIoA) to 1 (NaviCase, orthopedics and spine). Wide panels suit UR and appeals; for a hospital peer review of a narrow subspecialty, a firm built around that service line, such as Corazon for cardiovascular, neuroscience and orthopedics, may get you a closer peer.
Limits: Firm facts come from each firm's own website, read 2026-11-12; we haven't hired these firms or graded their reports, and "not stated" means we didn't find it, not that the firm doesn't do it.
Specialty counts, as each firm states them
Read the chart as "how wide the panel claims to be," not "how deep." A firm with 132 subspecialties might have 1 reviewer in pediatric interventional cardiology, and that reviewer might be on vacation. The number that matters is how many active reviewers the firm has in your exact subspecialty, in a practice setting like yours, with no tie to your hospital. No firm publishes that, so ask.
Which firms name which specialties
Most firms say "all specialties." A few name specialties or clinician types on their own pages. This table lists only those named mentions, so a blank doesn't mean a firm can't cover the area.
| Specialty or reviewer type | Firms that name it | What they say | Source, captured |

What "specialty-matched" means at each firm
20 of the 39 firms say they match the reviewer's specialty to the case. They mean slightly different things, and the difference matters when the reviewed physician challenges the report.
- Same or similar specialty. National Medical Reviews uses this standard for appeal-level reviews and adds that the reviewer is in active practice.
- Specialty plus practice setting. CIMRO says a precise match needs both specialty and practice setting; MRN says the same for OPPE reviewers. A rural general surgeon reviewed by an academic surgical oncologist is matched on paper but not in practice.
- Specialty plus state. MLS matches on state and specialty, and NMR adds a same-state license when the rules require it. That matters most in UR and appeals.
- Specialty chosen per case. MRN has a nurse consultant pick the reviewer for each case, from its database or by recruiting 1 for the case.
- Service line only. Corazon and NaviCase cover a narrow field, so every case lands with a reviewer from it.
Narrow subspecialties: what to ask before you send the case
For a subspecialty with few practitioners, such as pediatric cardiac surgery, interventional neuroradiology or transplant hepatology, the panel size on a home page is close to useless. Ask the firm 3 things in writing:
- How many reviewers do you have who hold this subspecialty board certification and still practice it?
- Do any of them practice in our state, our referral region or a health system we compete or partner with?
- If none fits, will you recruit 1 for this case, as MRN says it does, or route it to the nearest specialty?
A firm that can't answer the first question by name and number for your case is guessing. For hospital peer review, a near-miss reviewer is a weak point in any later fair hearing.
Questions about specialty coverage
Which medical record review company covers the most specialties?
By its own count, MRIoA, at 150+ specialties with 700+ physicians, followed by Medplace at 132 subspecialties. Counts use different units, so check depth in your subspecialty rather than the headline number.
Which firms specialize in a single field?
Corazon reviews only cardiovascular, neuroscience and orthopedic programs, and NaviCase prepares only orthopedic and spine records. Peer Review Plus is cardiology-led and still in testing.
Can an NP or PA be peer reviewed by these firms?
Medplace names advanced practice clinicians on its panel, and Quality Peer Solutions names licensed allied health professionals. Ask any other firm whether it can match an NP or PA with a peer of the same license type.
