When will I select CPT codes?
Grow Therapy's guided prescriber billing selects a CPT code based on the information you provide during documentation and invoicing. This gives Grow what we need to file the claim, bill your client, and process payment. For more on how guided billing works, see Guided prescriber billing.
How does Grow determine my CPT code?
For prescribers, CPT code selection is driven by two factors:
Time — the total time on the date of the encounter related to the service, including both synchronous and asynchronous time
Medical decision-making (MDM) — the complexity of the clinical decisions made during the encounter, assessed across three areas:
Problems: Number and complexity of problems addressed
Data: Amount and complexity of data reviewed and analyzed
Level of risk: Risk of complications and/or morbidity/mortality of client management
MDM requires that at least two of the three areas meet or exceed the threshold for the selected code.
What counts as "time" for prescribers?
Unlike therapist sessions, prescriber time includes both synchronous and asynchronous activity on the date of the encounter. The following are included:
Preparing to see a client (e.g., reviewing tests or records)
Obtaining and/or reviewing separately obtained history
Performing a medically necessary exam and/or evaluation with the client present
Counseling and educating the client, family, or caregiver
Ordering medications, tests, or procedures
Referring and communicating with other healthcare professionals (when not reported separately)
Documenting clinical information in the health record
Independently interpreting results and communicating them to the client or family
Care coordination (when not reported separately)
Checking the state PDMP when prescribing controlled substances
Add-on codes for prescribers
Add-on codes represent additional time dedicated to psychotherapy services during a session when provided alongside an Evaluation and Management (E/M) service.
CPT Add-On Codes, Prescribers | Minimum Duration |
90833 | 16–37 minutes |
90836 | 38–52 minutes |
90838 | 53+ minutes |
Prescribers record time spent on psychotherapy services in the notes section of documentation and invoicing. If the add-on code doesn't match the documented time, a time-based error will appear.
To resolve the error, select a code that aligns with the total psychotherapy time documented, or return to your note and adjust the time.
