Medical practice bookkeeping has two sides, and they should run separately. On the income side, money comes from insurers, patients and third parties that order an exam or a report. It is tracked in your practice management software, and the remittances and statements behind it name patients. On the expense side sit medical supplies, rent, software, equipment maintenance and continuing medical education. That side doesn't name patients, and there an AI can take on the groundwork: collecting bills, matching them to bank and card transactions, listing gaps and assembling the package for your bookkeeper or CPA. Posting and tax judgement stay with them.
This is not legal or tax advice. The US rules cited come from HHS and the IRS, with a short section on Germany at the end; status November 2026. What else AI employees can take over in the practice office is in AI Tools for Doctors: The Practice Office.
Medical practice bookkeeping: where the money comes from
A lump-sum insurance deposit is just a number until your bookkeeper gets a summary by payer and date. Agree on one without patient names, exported from your practice management software. The bank statement itself can show patient names too, so before an AI sees any transactions, decide which lines it gets, for example only the expense side. How to follow up on unpaid patient balances is in Patient Collections for Medical Practices.
PHI in medical practice accounting
Remittances, patient statements and deposits that carry a patient's name are protected health information. Whoever works with them for your practice is likely a business associate; the definition names "billing" among the regulated functions and "accounting" and "financial services" among the services (45 CFR 160.103). Before PHI goes to such a person or vendor, you need "satisfactory assurance that the business associate will appropriately safeguard the information" (45 CFR 164.502(e)), usually in the form of a business associate agreement. That includes outside bookkeepers, CPA firms and any AI tool reading those documents.
For bookkeeping, the minimum necessary standard is the more useful rule. Covered entities "must make reasonable efforts to limit protected health information to the minimum necessary to accomplish the intended purpose" (45 CFR 164.502(b)). Posting a deposit needs the payer and the amount, not the patient list. In practice that means: an AI works on expenses and payer-level totals, while claim and patient detail stays in your billing system and with the vendors you have agreements with. My questions for deciding what an AI may see are in AI and Privacy: What the AI Gets to See.
What your accountant needs, by rhythm
What goes in and when, you agree with your bookkeeper or CPA. A structure to adapt:
For the income side, a short note per month saves the back-and-forth:
Deposit note [month year], [practice name]
Insurance deposits: [count], total [amount], summary by payer attached: yes/no
Patient payments: total [amount], from [software report name]
Third-party exams and reports: total [amount]
Unmatched deposits: [date, amount, payer if known]
Question for you: [question]
How long to keep records
For tax records, the IRS standard period is three years ("Keep records for 3 years if situations (4), (5), and (6) below do not apply to you"). Payroll is longer: "Keep employment tax records for at least 4 years after the date that the tax becomes due or is paid, whichever is later." Six years apply if you fail to report income that is more than 25 percent of the gross income shown on your return. Medical records are a separate matter with their own retention rules, and they belong in the EHR, never in the receipts folder. For the general groundwork, see Bookkeeping Basics for the Self-Employed.
If your practice is in Germany
German practices get statutory insurance income through the regional association of statutory health insurance physicians (KV). The KV "verteilt die vereinbarten Gesamtvergütungen an die Ärzte" (section 87b SGB V) and pays monthly advances, with a final settlement after the quarter. Terms differ by KV; in Bavaria, the settlement for the first quarter of 2026 was scheduled for July 31, 2026. Medical treatment is VAT-exempt (section 4 no. 14a UStG) only where a therapeutic aim comes first; according to the VAT guidelines (UStAE 4.14.1), reports for insurers and pre-employment exams are not exempt, and aesthetic procedures only where they treat an illness, injury or congenital defect. Since a Ministry of Finance letter of May 21, 2026, the practice bears the burden of proof and documents that medical indication for each patient in anonymized form. Supplies the practice buys itself (Praxisbedarf) are its expenses; supplies prescribed at the insurers' cost (Sprechstundenbedarf) are not, when the supplier bills the payer directly. DATEV offers a chart of accounts for doctors based on SKR 03 or SKR 04, see DATEV Integration: The Basics; incoming e-invoices are covered in German E-Invoicing: Dates and Exemptions.
Where German documents do name patients, my data lock can help. The data lock sits between your team and Claude. Before a request goes to Claude, it replaces names and other details that point to a person with placeholders. Claude gets the placeholders instead of the names. When the answer comes back, the data lock puts the real names back in, and you read plain text. The list of which placeholder stands for whom stays on our server in Germany. The data lock is ready for use and already in operation. I set it up for your practice individually and tailor it to its work. Pseudonymized data is still personal data, and since no automatic detection catches every detail, we also agree on what never goes to Claude in the first place.
Who does what: Peter and you
Since August 19, 2026, Peter, my AI employee for receipts and bookkeeping, has been working in my business. Inside my bookkeeping interface in the browser, he screens incoming receipts, gives each one its receipt type, checks the credit card statement against them line by line and flags anything that doesn't match. His first run: 116 receipts screened, 38 of 40 matched correctly, just over an hour of work, for groundwork that otherwise takes my bookkeeper about 9 hours a month. Booking entries is not his job. Here's how you use him in a medical practice:
The section "What else Peter can take on" on his page covers exactly this ground, from preparing the bookkeeping and talking to your tax adviser to checking invoices and payment reminders. Peter can do all of it, tested. For me he runs the receipt matching and uploads my receipts to DATEV every month; how he handles reminders for you is in Automate Payment Reminders and Dunning. To set it up, you write down the third column once, he learns it in read-only mode with screenshots, you test it on real cases, then you approve it. Supplier bills that come in by email can go through Frieda first, who sorts the admin inbox; for her, receipts are a waystation, not an archive.
None of this works without your accountant. According to Peter's page, you and your adviser agree on handoff format, responsibility boundaries and review steps, and the adviser has to be able to take the prepared data. In my business there's one more rule: whoever produced something does not check it. How you set this up in your practice, we can look at together.

Frequently asked questions
What does medical practice bookkeeping include?
Income: deposits matched to payer summaries from the billing system. Expenses: supply, rent, software and service bills collected, coded and reconciled against bank and card statements, then handed over monthly.
Does my bookkeeper need a business associate agreement?
Usually yes, as soon as they handle PHI on your behalf. Sending payer-level summaries instead of patient detail keeps what they see to the minimum necessary.
How long should a medical practice keep financial records?
Three years in the IRS standard case, at least four for employment tax records, six if unreported income exceeds 25 percent of reported gross income. Medical records have their own rules.
Can AI do the bookkeeping for a medical practice?
It can do the preparation: expense bills, statement matching and payer-level deposit checks. Patient detail stays out unless an agreement and safeguards are in place, and posting stays with your bookkeeper.
