Prior Authorization for Treatment
Prior Authorization List
IMPORTANT NOTE: Prior authorization is based on medical necessity and is not a guarantee of coverage or eligibility. If a service is not included on this list, the service does not require prior authorization. However, this does not mean it is a covered benefit.
Only valid codes will be reviewed. Please refer to CMS/MC guidelines to verify validity. Codes are updated regularly and posted below.
It is expected that all services requiring prior authorization must be authorized before providing the service, with the exception of services that are necessary on an emergent or truly urgent basis. For authorization requests submitted prior to the date of service, expect a response from HPSM within:
- Three business days for urgent or expedited authorization requests
- Five business days for routine authorization requests
Before submitting a request, search HPSM's Prior Authorization List by CPT code or service name to see if you need to get prior authorization:

The HPSM Prior Authorization Required List states which service codes require prior authorization. Services not listed here do not require prior authorization. For services on this list, complete the Prior Authorization Request Form and fax it to HPSM at 650-829-2079.
Your PAR will be rejected if you submit:
- An outdated version of the form
- An incomplete form
- Inaccurate information
- A form filled out in handwriting
- A PAR with multiple patients’ information
HPSM recommends adjusting your fax machine settings to the highest quality possible, and double-checking the member ID number before sending. If you have any questions about the PAR, please consult the Prior Authorization Request Form User Guide or call Provider Services at 650-616-2106.
