Most speech-language pathology codes do not have time units assigned to them, such as 92507 (speech-language treatment). If no time is noted in the descriptor, each code counts as one session. A complete list of the CPT codes for speech-language pathology services is available in the ASHA Medicare Fee Schedule or the ASHA Model Superbill for Speech-Language Pathology Practice [DOC].
Yes. They are:

If the treatment code (92507) is revised, the development of additional treatment codes that could address complexity of services would be considered at that time. ASHA would have to present evidence that the services are different in terms of the time it takes to perform the service, the level of technical skill, the physical effort, the required mental effort and judgment, and the stress due to the potential risk to the patient.
Determining what might be considered a "typical" for an untimed code is difficult. Ultimately, it will come down to the judgment of the clinician and whether he/she feels they can make progress with the patient during the evaluation or treatment session, whatever the amount of time may be. However, untimed codes do have any underlying "typical" time associated with each code. These times are derived from surveys of speech-language pathologists that ASHA conducts in conjunction with the American Medical Association. These typical times are located in what's called the Physician Time File, which is publicly available through the Centers for Medicare & Medicaid Services (CMS).
These underlying "typical" times may be used as guidelines. However, there are no hard and fast rules regarding time "minimums" for untimed codes. Ultimately, the decision to bill a code depends on the clinician’s judgement and documentation to support that the time spent with the patient was medically necessary and clinically appropriate for that patient on that day.

Historically, the physical medicine and rehabilitation procedure codes were assigned time units of 15 minutes while the codes for speech-language pathology were not. Because of the way codes are developed and established, it is difficult to revise descriptors without significant impact to reimbursement.
Occasionally, I must spend an extremely long period of time rendering an evaluation or treatment session. Is there a way to be reimbursed an extra amount in recognition of the inordinate amount of time?
One of the CPT modifiers is -22, added at the end of the CPT code. This modifier denotes a session or procedure that is unusually long. Many payers will increase reimbursement by 25 to 50 percent when this modifier is included, but the claim will be stopped for manual review and you will need to submit additional documentation with your claim to justify the increased services. Be warned that if you submit claims with the -22 modifier too often, the payer may conclude that the long sessions are not "unusual," and cease to honor the modifier.
No. Medicare has established specific minimum and maximum times for 15-minute codes and most payers have adopted this policy. The minimum time for one 15-minute code is 8 minutes. Two units would be a minimum of 15 + 8 minutes = 23 minutes. This rule is extended to multiple units in the following CMS table:
1 unit: 8 minutes to < 23 minutes
2 units: 23 minutes to < 38 minutes
3 units: 38 minutes to < 53 minutes
4 units: 53 minutes to < 68 minutes
5 units: 68 minutes to < 83 minutes
6 units: 83 minutes to < 98 minutes
Medicare specifies that evaluation or assessment procedures may be billed only once per discipline, per date of service, per patient (CPT 92521, 92522, 92523, 92524, 92597, 92607, 92611, 92612, 92616). Additionally, treatment codes may be subject to Medicare's Medically Unlikely Edits (MUEs), which specify how many times a code may be billed per date of service. For instance, the MUE for CPT 92507 prevents this code from being billed more than once in a day. Many payers will adopt Medicare policy.
