The solution

Write letters that insurers can understand and approve

Twofold helps you generate letters of medical necessity that connect diagnosis, symptoms, function, and proposed treatment so reviewers see exactly why care is required.

  • Clear Statement Of Diagnosis And Symptoms

    Pull key diagnoses, severity, and relevant history into the opening of each letter so payers quickly see what the request is about.

  • Functional Impact And Risk Description

    Describe how the condition affects work, school, self care, relationships, or safety using language that matches payer criteria.

  • Summary Of Prior Treatment Attempts

    Document what has already been tried, how the patient responded, and why additional or different care is needed.

  • Requested Service And Rationale

    State clearly what you are requesting, how it aligns with guidelines, and why it is medically necessary for this specific patient.

  • Support For Duration And Frequency

    Justify how often and how long services, medications, or equipment are needed, tied directly to clinical goals.

  • Payer Friendly Structure

    Use headings and organized paragraphs that make chart reviewers and utilization management teams more likely to read and approve.

  • HIPAA Compliant Letter Generator

    All PHI is encrypted in transit and at rest, handled under a signed BAA so you can safely generate letters that include clinical detail.

  • Copy Ready For Portals And Faxes

    Paste the finished letter into electronic portals, secure messages, or fax cover pages without losing formatting.

@Twofold_Health wow this is hands down the best scribe I've tried. I love your app.

Marylin Zertuche
Marylin Zertuche MD

Went from spending 3+ hours on notes to under 30 minutes. Wish I had found @Twofold_Health sooner. My patients get better care now because I'm less burned out.

Dr. Priya Nair
Dr. Priya Nair MD

@Twofold_Health is amazing in that I could really focus on my patient instead of bouncing between them and the computer screen. I'm submitting my notes right away and not on weekends!

Kelly Perez
Kelly Perez PCP

@Twofold_Health is very easy to navigate and it has saved me time and energy with finishing documentation. Today I'm more motivated to finish my notes at the end of the day. I'm SO glad I found this!

Cristina Riske
Cristina Riske NP

I recommend @Twofold_Health to every colleague who complains about documentation burden. The time savings alone make it worth every penny.

Laura Mendez

Cut my charting time in half. I can actually leave the office on time now. This tool is a genuine game-changer for work-life balance.

Rebecca Santos
Rebecca Santos PA-C

Family med is wild. Chronic care visit, then a sick toddler, then a Medicare wellness — all in one afternoon. Twofold just keeps up. I'm not picking templates anymore.

AR
Aisha Robinson MD

Was honestly skeptical. Three weeks in, my charts were caught up for the first time in like, years? Now i tell every new partner about it on day 1.

TV
Tomás Vela MD

my follow-ups are usually 5–6 problems deep and the A&P comes out structured per dx without me babysitting it. coding suggestions are usually right too which is wild.

JW
Jordan Whitaker MD

Hospitalist work is just a wave of admissions all day. With this I'm done before signout. That used to be unthinkable.

EV
Elena Vasquez DO

Worked through a PE rule-out yesterday and the note basically wrote itself. Cardiopulm exam, d-dimer reasoning, the whole dispo. Saved me at least 20 min on a busy shift.

MR
Mateo Reed PA-C

discharge summaries used to ruin my Fridays. now i dictate the hospital course on the way to the parking lot and twofold handles the rest. it's a different job

DC
Daniel Cho MD

Well-checks, sick visits, asthma follow-ups — all in the same morning. Asthma action plans come out clean and parents leave with the printed copy without me opening a template.

BD
Brett Donovan MD

Adolescent visits with sensitive content (depression screens, sexual health) — Twofold handles the confidentiality framing well. I don't worry about a parent reading something they shouldn't. I trust it.

NP
Naomi Patel PA-C

Med-management used to bleed into my evenings every single day. Now MSE, risk assessment, prescribing rationale come out structured the way i'd write them. I have evenings again. real ones.

SL
Sasha Lee MD

Controlled-substance documentation is structured exactly the way my state board wants it — PDMP review, treatment agreement, risk-benefit. I stopped dreading audits.

ET
Eli Tanaka MD

I think it is amazing. One of the biggest positives for me is that it validates the work that I put into a session. It always catches things that I would miss. 10/10 @Twofold_Health

Tristian Palmer
Tristian Palmer LCSW

Amazing @Twofold_Health! It works so well with couples/families (multiple voices) and exports well to other filing applications. I love the feature of writing a follow-up email to clients!

Aiyana Osterman

I am in love with @Twofold_Health. I can't tell you how grateful I am to cut down the time I spend on notes.

Anthony Mitchell
Anthony Mitchell PMNHP

I'm always concerned about completing my documentation and being in compliance for insurance claims. @Twofold_Health helps me with creating beautiful notes in a fraction of the time.

Jenny Heil

It saves so much time and stress. @Twofold_Health has truly had a positive impact on my own mental health. Thanks for making such an amazing program.

Janelle West
Janelle West LSW

Totally amazing. I am your number 1 fan

Stephen Huber
Stephen Huber Psychiatrist

Perfect for therapy notes. It picks up on emotional nuance in conversation that I'd normally struggle to document accurately. My notes have never been better.

Marcus Davis
Marcus Davis LMFT

solo primary care, panel of about 1100. a1c trends, weights, BPs — all just there when i open the chart. don't know how i did this job before tbh

DH
Devon Hayes FNP-BC

AGNP, panel north of 1200. The med rec alone gives me back like an hour a day — every dose change carries forward visit to visit and i don't have to dig through old notes.

SK
Saanvi Krishnan AGNP-C

Bright Futures language, growth percentiles, anticipatory guidance — all of it ends up in the right section automatically. I'm out the door on time, which is wild for peds.

RP
Ramona Park MD, FAAP

peds visits are SHORT and full of family voices and twofold attributes parents vs patient correctly every single time. that alone is worth it honestly

MS
Maya Sharma CPNP

triage and immunization docs are way faster. lot numbers, VIS dates, all structured for our IIS — i was dreading immunization clinic days and now they're fine

SD
Sara Donaghue RN, CPN

I do integrated psych evals. Twofold handles the formulation, MSE and plan in a structure that holds up to peer review — and the case-conceptualization narrative still sounds like me, not a robot.

RB
Renée Boudreaux PsyD

half my caseload is trauma. the PE/CPT-aligned language is actually thoughtful, not just keyword stuffing. saves me from rewriting every note which i used to do constantly

AA
Adesola Ajayi LMHC

heavy panel — twofold tracks meds, side effects, PHQ-9 trends visit-over-visit so i can actually look at the patient instead of the chart. that part shouldn't be revolutionary but it kinda is

TJ
Trevor Johnson PMHNP

as a resident, getting clean H&Ps that my attending signs without re-writing? unreal. made my last inpatient month tolerable

NF
Noor Foster MD, PGY-3

ROM, MMT, special tests — all there exactly the way i'd write them. my initial evals are done before i leave the treatment room. that did not used to be true

OT
Olivia Tran PT, DPT

Twofold actually understands rehab docs — outcome measures, plan of care, recerts, all in a Medicare-compliant structure. No more nightly chart catch-up. I stopped working from my couch.

MR
Marcus Reed PT, DPT, OCS

ADL/IADL assessments come out in the format i use for OT evals. The time i get back goes back to my patients, full stop.

RB
Riya Bennett OTR/L

daily treatment notes used to be 20 min per patient. now it's 3. same compliance, same detail, way less typing. ngl this changed my whole workflow

TE
Tom Ellis PTA

Documentation finally feels like part of treatment instead of the thing i have to do after. Game-changer for SNF work.

TL
Tomas Lawson COTA/L

i bounce between a clinic, a high school, and a college program. mobile capture means i'm not chained to a desk — notes get done on the bus ride home which is where i'd rather do them anyway

RC
Riley Chen ATC

Artic and language goals used to mean endless copy-paste. Twofold tracks cueing level and percent accuracy cleanly visit to visit, so my progress reports actually show progress.

AR
Abigail Reyes MS, CCC-SLP

school sessions with mixed groups are finally documentable without chaos. attendance, target goals, and homework all land in the right place — i can run six kids in 30 min and still have the note done

CH
Connor Hale SLP

For dysphagia follow-ups it captures PO trials and compensatory strategies in a structure my rehab team can actually use. They stopped DMing me asking what i meant.

IB
Imani Brooks MA, CCC-SLP

as a CF, writing strong plans was my bottleneck. twofold gives me a solid first draft that still sounds like me. saved my sanity tbh

LM
Lucas Meyer SLP-CF

Cognitive-comm sessions are nuanced and the tool actually captures real functional progress instead of generic template language. That's rare.

NF
Nadia Farouk CCC-SLP

outpatient peds and adults in the same day used to wreck me. twofold adapts without me switching formats every hour

PV
Peter Vaughn MS, CCC-SLP

nutrition counseling notes are finally fast AND consistent. assessment, intervention, monitoring — done in one pass. feels like cheating

LM
Leah Morgan RD, LD

For DM follow-ups it captures carb goals and adherence barriers exactly how I actually discuss them with patients. Doesn't scrub the personal stuff out which is the whole point.

DK
Darren Kim RD, CDCES

telehealth visits move fast. twofold keeps pace and i'm closing charts before the next session starts which is genuinely a first for me

HO
Helena Ortiz MS, RDN

Behavior-change plans used to get buried in free text. Now goals, barriers, next steps are obvious to the whole care team — my MA actually reads my notes again.

SG
Samir Gupta CNS

weight-management documentation is so much cleaner now. trend lines that i can actually point at during a visit. patients respond to that better than my old word salad

JW
Jocelyn Wade RD

I cover oncology nutrition — i need precise, practical notes. Twofold saves me time without losing clinical detail, which i was worried about going in.

MA
Miguel Alvarez RD, CSO

Latch assessments are clearer and faster now. I finish charting while the feeding plan is still fresh in my head — i used to forget the small stuff by the end of the day.

NR
Naomi Rivera IBCLC

home visits used to be impossible to document on time. now i capture positioning changes and parent coaching right there in the room. parents don't even notice

EC
Erin Caldwell CLC

For postpartum follow-ups it organizes symptoms, transfer observations and next-step guidance in a chart-ready format. The whole care team's on the same page now.

MP
Monica Price RN, IBCLC

i love that it captures exactly what education i covered with families. continuity between visits is so much better — i'm not asking the same questions over and over

CS
Caroline Shaw IBCLC

In our busy postpartum unit, doc speed matters a lot. Twofold helps me keep notes complete without staying late. That's everything for me right now.

TN
Tessa Nguyen CNM, IBCLC

when feeds are complicated i need detail and structure both. this gives me both, no extra clicks. i don't remember what i did before
