A 38-provider ENT group · ENT / Allergy

We ran 100 ModMed faxes through ModMed's AI sorter and Blue. Both flagged all 45 true referrals; Blue flagged 38% fewer faxes that weren't referrals.

ModMed ships an AI fax sorter. We wanted to know how it compares with Blue, so we took 100 inbound faxes from a 38-provider ENT group on ModMed and ran them through both.
We pulled 100 consecutive faxes from the practice's ModMed inbox. A person read every one and decided whether it was a true referral: a new patient being sent to the practice for care. Then we compared that answer with how ModMed's sorter and Blue classified each fax. 45 of the 100 faxes were true referrals.
Neither AI missed a referral. The difference is in false flags: against ModMed's sorter, Blue cut them by 38%.
ModMed's false flags were mostly paperwork with nothing referral-like in it: lab results, a sleep study report, requests for medical records, a letter from a palliative care doctor, a surgery scheduling form, and a request to re-send a fax that came through cut off.
Blue's false flags were closer calls. They were documents that read like referrals but weren't new ones: pre-op clearance notes from a primary care doctor, a referral for physical therapy, appointment confirmations, a prescription request, and a thank-you-for-the-referral note sent to the wrong office.
That difference matters for the front desk. Every false flag is a fax someone has to open and set aside, and if outreach runs automatically, it's a patient who gets a message they didn't need.
We used the misses to tighten Blue's instructions, then ran the same 100 faxes again. On the recheck, Blue sorted all but one of its false flags correctly. The one it still gets wrong is a fax asking whether a previously referred patient was ever scheduled. It mentions a referral, but it isn't a new one.
Because the recheck used the same faxes we tuned on, it shows the fix works on this sample. The next batch of new faxes is the real test, and we'll publish that number when we have it.
Sorting is the first step. For each referral, Blue also pulled the structured data the front desk keys into the EHR by hand: the reason for referral (often with the ICD-10 code), the referring provider, and the insurance plan when the fax listed one. Blue can then text the patient a link to schedule.
You don't have to turn off ModMed's sorter to use Blue. ModMed delivers faxes as PDFs, which Blue reads directly; staff drag a batch into Blue once or twice a day and run it.

No. Blue runs on the faxes ModMed already receives. In this test, both caught every true referral; Blue flagged fewer faxes that weren't referrals, and it extracts referral details and texts the patient.
A person read all 100 faxes and marked each one. A true referral is a new patient being sent to the practice for care. Pre-op clearances, records requests, lab results and scheduling confirmations don't count.
Before. It compares Blue's first pass with ModMed's sorter on the same 100 faxes. The after-tuning recheck is reported separately because it reused the same faxes.

Indiana Sinus Centers
The final text told 122 dormant patients we were closing their file. Thirteen replied and two booked surgery, beating the polite follow-up before it. The full three-round math.

Indiana Sinus Centers
Indiana Sinus Centers texted the 128 patients still dormant after round one. Eleven re-engaged, four more scheduled surgery, and all four round-one surgeries are confirmed on the calendar.

Michigan ENT and Allergy Specialists
A large multi-location ENT & allergy group ran 3,800 faxed referrals through Blue. 1,630 patients were texted to self-schedule automatically — 43% of every inbound fax — with zero staff calls.
