The person behind the product
Jimenez Julien, publisher and maintainer of SuperbillDesk
He writes the code, answers the support mail, and takes the call when a superbill needs a field it does not yet have.
Why he built SuperbillDesk
The first version of SuperbillDesk was a favor. A marriage and family therapist in Sacramento described her month end routine over a long call: export the card reader report, open a Word template she had inherited from a supervisor in 2016, retype twenty two client names, look up whether each one had been a 45 minute or a 53 minute session, and hope she had the right diagnosis code on file for each of them. She estimated four hours. She was underestimating, because she was not counting the follow up messages that arrived two weeks later when an insurer rejected a statement for a missing rendering provider number.
What struck him was that none of it was clinical work, and none of it was hard. It was a data joining problem wearing the costume of an administrative burden. The session ledger already knew the date, the length and the fee. The client record already knew the diagnosis and the place of service. The practice already knew its own NPI and EIN. Nothing needed to be invented. Those facts simply needed to meet each other on one page, on a schedule, in a format an out of network claims adjuster would accept without argument.
So he built the joining. Then he sat with eleven more practices, in Texas, Michigan, Rhode Island, Oregon and upstate New York, and watched the same four hours evaporate in eleven slightly different ways. Group practices had a worse version of the problem, because the rendering provider changed per client and the spreadsheets multiplied per clinician. Training clinics had the worst version, because supervisor attestations had to appear on statements for pre licensed staff and nobody could remember which sessions those were.
He is careful about the boundary of the product, and that boundary is deliberate. SuperbillDesk does not file claims. It does not contract with payers. It does not hold clinical notes, and it never asks for them. It produces the itemized statement that an out of network client submits themselves, and it delivers that statement on a predictable day with a record that it was delivered. Keeping the scope narrow is what allows a single person to be genuinely accountable for it.
He also has a rule about mental health work in particular: the software must never make a clinician feel surveilled. There is no productivity scoring, no comparison of one clinician against another, no nudge that a caseload is below some target. The product looks at billing artifacts and stays out of the room. Several clinical directors have told him that this is the reason their staff accepted it without a fight.
Experience and expertise
Jimenez Julien has spent his working life building small operational tools for people who did not choose software as a career. Before SuperbillDesk he shipped scheduling, dispatch and document tools for trades where a missed detail costs real money on the same day. That background shapes how he treats a superbill: as a document that either gets paid or does not, with no partial credit.
- Direct work with 638 United States private practices, from single clinician offices to a twenty three clinician training clinic.
- Familiarity with the outpatient behavioral health code set in daily use: 90791, 90832, 90834, 90837, 90846, 90847 and the telehealth modifiers that travel with them.
- Practical knowledge of what out of network claims adjusters reject and why, gathered from more than four hundred rejection letters that practices have forwarded since 2024.
- Product and editorial responsibility for every word on this site, including the pricing table and the claims made about outcomes.
How this product is built and maintained
SuperbillDesk is published by MLJ, SASU, a small French company with one operator. There is no outsourced support desk and no offshore content team. Every feature ships after it has been used against a real practice month, not against a sample data set. When a code set or a payer expectation changes, the change is made in the product first and then written into this site, in that order.
Editorial standards are simple and enforced. Numbers on this site come from product telemetry or from named accounts who agreed to be quoted, never from a stock industry report. Testimonials are published with a full name, a license, a business and a city, and the person quoted has read the exact wording before it appeared. Nothing on the site is written by a content agency. If a claim cannot be traced to a delivery log, an approval timestamp or a signed permission, it does not get published.
Maintenance is boring on purpose. Dependencies are reviewed monthly, backups are restored to a scratch environment quarterly so that restoration is a rehearsed action rather than a hope, and the delivery pipeline is tested against a real client statement before every release. Security questions from clinical directors are answered by the person who wrote the code, in writing, usually the same day.
