Inside Pay-Per-Visit AI Charting: What Counts as a Billable Credit
product
A deep dive into how a single wound visit becomes one finished chart, one credit, and what happens inside the six agents that produce it.
Pay-per-visit sounds simple on a pricing page. Under the hood, it depends on a precise definition of what a finished chart is and what has to happen before a credit is consumed. This is that mechanism, in detail.
The unit of billing is the signed SOAP note
A credit is not triggered by opening a chart, capturing an image, or drafting a note. It's triggered when the AI has produced a complete, coded, audit-ready SOAP note and the clinician signs it. Drafts that are abandoned, duplicated visits caught before signing, and manual-only notes do not count.
What the six agents do before that credit is spent
| Agent | Input | Output | Time |
|---|---|---|---|
| Wound imaging | Phone camera capture | Border, area, depth, description | Seconds |
| Charting | Ambient audio + image data | Draft SOAP note | ~2 minutes |
| Coding and billing | Signed note + payer rules | ICD-10, CPT, HCPCS, prepped claim | Parallel |
| Healing trajectory | Visit-over-visit measurements | Trend line, guideline flags | Parallel |
| Patient education | Signed plan | Plain-language home instructions | Seconds |
| Chart-Chat (Pingoo) | Clinician query | Cited answers from the record | On demand |
All six run under one credit per finished chart — you don't get billed six times.
Why the unit lines up with revenue
A finished wound visit generates a claim. That claim, on average, bills two to three orders of magnitude more than the AI credit that produced the documentation. The cost tracks the work the AI actually saves — measurement, dictation, coding lookup, education handout — not access to a login.
What clinicians still own
Every draft is reviewed, edited, and signed by the clinician before submission. The AI never signs, never submits, and never generates a credit without a human signature.

What isn't billed
- Reading or reviewing existing records
- Editing a previously signed note (with proper amendment trail)
- Adding covering providers, admins, or students as users
- Storing images and prior encounters
- Running the healing dashboard across your patient panel
