Update on type of service (TOS)



Medicare carriers must use the following table to assign the proper TOS. Some procedures may have more than one applicable TOS. For claims received on or after April 3, 1995, CWF will produce alerts on codes with incorrect TOS designations. Effective July 3, 1995, CWF is rejecting codes with incorrect TOS designations. All future updates will be submitted via a Recurring Update Notification.

The only exceptions to this table are:

• Surgical services billed for dates of service through December 31, 2007, containing the ASC facility service modifier SG must be reported as TOS F. Effective for services on or after January 1, 2008, the SG modifier is no longer applicable for Medicare services. ASC providers should discontinue applying the SG modifier on ASC facility claims. The indicator ‘F’ does not appear in the TOS table because its use depends upon claims submitted with POS 24 (ASC Facility) from an ASC (specialty 49). This became effective for dates of service January 1, 2008 and after.

• Surgical services billed with an assistant-at-surgery modifier (80-82, AS,) must be reported with TOS 8. The 8 indicator does not appear on the TOS table because its use is dependent upon the use of the appropriate modifier. (See Pub. 100-04, Medicare Claims Processing Manual, Chapter 12, "Physician/Nonphysician Practitioner," for instructions on when assistant-at-surgery is allowable.)

• Psychiatric treatment services that are subject to the outpatient mental health treatment limitation should be reported with TOS T.

• TOS H appears in the list of descriptors. However, it does not appear in the table. In CWF, "H" is used only as an indicator for hospice. The carrier should not submit TOS H to CWF at this time.

• For outpatient services, when a transfusion medicine code appears on a claim that also contains a blood product, the service is paid under reasonable charge at 80%, coinsurance and deductible apply. When transfusion medicine codes are paid under the clinical laboratory fee schedule pay at 100%, coinsurance and deductible do not apply.

The place of service or diagnosis may be considered when determining the appropriate TOS. The descriptors for each of the TOS codes listed in the following table are:

I need some help here. I am needing to obtain benefits for Outpatient Surgery performed in a Specialist Office. I am contacting SecureHorizons through United HealthCare. I keep getting different answers. Can someone please explain what benefit the Outpatient Surgery performed in a Specialist Office falls under? SecureHorizons does not have a seperate benefit listed like that. It is either Outpatient Surgery or the Office Visit. I know the Office Visit does NOT include the surgery as far as benefits. I may be wrong but that is how I understand it. Please help me out on this. Thank You.
