What 90785 covers

Code 90785 captures added communication work during a psychiatric service, not a separate evaluation or a longer psychotherapy session. Examples include using play equipment to communicate with a young child, working through an interpreter, coordinating with a third party whose involvement complicates the exchange, or addressing a disclosure that requires mandated reporting. Psychiatrists, psychologists, clinical social workers, and other qualified mental health clinicians may encounter these circumstances in office or facility settings.

Report 90785 only with an eligible primary psychiatric service, such as a psychiatric diagnostic evaluation or psychotherapy; it is not billed by itself. The record should identify the communication factor and explain how it affected delivery of the primary service. CMS classifies it as an add-on paid within the primary procedure’s global period, so submit it with that procedure rather than as a standalone service.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

90785 billing questions

When should 90785 be added to a psychiatric service?

Use it when a specific communication factor complicates delivery of the primary psychiatric service, such as interpreter use or communication through play equipment. The record should explain the factor and its effect on the encounter.

Can 90785 be billed by itself?

No. It is an add-on code and must be reported with an eligible primary psychiatric procedure, such as 90791, 90792, or a psychotherapy service.

Does a difficult or lengthy session alone support 90785?

No. Session difficulty or length alone does not establish interactive complexity; document the specific communication circumstance that complicated the service.

Is interpreter use an example of interactive complexity?

It can be when an interpreter is needed to overcome a communication barrier during the psychiatric service. Document the interpreter’s role in facilitating the clinical exchange.

How does CMS treat payment for 90785?

CMS treats 90785 as an add-on paid within the primary procedure’s global period. Submit it with the primary service.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
