How does guided prescriber billing work?
Grow's guided billing workflow automatically generates a CPT code based on the information you provide during documentation and invoicing. The system is designed to reduce billing errors and get you paid faster — without requiring manual CPT code selection.

How is my CPT code generated?
The system determines your CPT code based on the following:
Client type — whether the client is new or established, which determines which codes are displayed
Psychotherapy — if psychotherapy was provided, MDM billing is used for code selection
No psychotherapy — billing can be generated based on time with MDM, or Psychiatric Diagnostic Evaluation with Medical Services
For a full breakdown of how time and MDM factor into code selection, see CPT code selection during invoicing | Prescribers.
Key features of guided billing
Key details and functionality of guided prescriber billing:
Smart detection — distinguishes between new and established clients, surfacing only relevant codes
Service type selection — select whether psychotherapy was provided, which influences billing options
Guided Assessment: — select answers from drop-downs for Problem complexity, Data review, and Risk level
Automatic calculation — applies the CMS "2 of 3" rule to determine MDM level and recommend codes
Validation checks — built-in safeguards prevent common errors before invoices are submitted
Why can't I manually select my CPT code?
Guided billing uses built-in guardrails based on CMS guidelines to minimize errors and reduce time spent on manual code selection. The system does not override your clinical judgment — your MDM selections and documented time drive the final code.
How do I change the psychotherapy add-on code?
The psychotherapy add-on code is based on the time spent on psychotherapy services documented in your notes. To return to your notes from the invoicing screen, select the back arrow icon in the upper left of the invoicing page.
To indicate that you provided psychotherapy:
Navigate to the Interventions section of your note and locate the "Treat (therapeutic interventions)" subsection.
Check "Provided psychotherapy," and the "Total time spent on psychotherapy services" drop-down menu will populate, as seen in the example below.
Once you do this, the add-on code will update to reflect the new time.
🛠️ Using off-platform notes or "Skip note"? You'll need to manually enter psychotherapy time on the invoice to bill a psychotherapy add-on code.
How do I change the E/M code?
To update the E/M code, adjust the MDM levels (Problem complexity, Data review, and Risk level) or time in session from the "Invoice Details" section.
Troubleshooting
What if I disagree with the selected CPT code?
