Use this form to request an exemption from participating in the OAS CAHPS survey for the calendar year (CY) 2027 Annual Payment Update (APU) period based on the number of eligible procedures. Click here to review and print a hardcopy of the PER form before entering the counts on the online form.

When is the exemption in force? The exemption is in force for the CY 2027 APU period, which is January 1 through December 31, 2025. The exemption is good for one year. Facilities must reapply to request an exemption annually.

Who can apply for the exemption? Hospital outpatient departments (HOPDs) and Ambulatory Surgery Centers (ASCs) that meet OAS CAHPS eligibility and served fewer than 60 OAS CAHPS survey-eligible patients between January 1 and December 31, 2024 can request an exemption. On an annual basis, CMS reviews all participation exemption requests and makes a determination to approve or deny. NOTE: ASCs that served fewer than 240 Medicare Fee for Service patients for the same reference period are automatically exempt and do not need to submit this PER form.

What does the exemption mean? Exempt HOPDs and ASCs do not need to participate in the OAS CAHPS Survey for the CY 2027 APU OAS CAHPS Survey data collection period, which runs from January 1 through December 31, 2025.

This form will assist you in determining if you have fewer than 60 OAS CAHPS-eligible patients.

Instructions for Completing the Participation Exemption Request Form

• Step 1: enter the hospital's 6-digit CCN or ASC's 10-digit CCN. ASCs will also enter the NPI (National Provider Identifier)
• The system will display the facility name associated with the CCN or NPI from Step 1. If the facility name on record is incorrect, please contact your State Survey Agency.

• Step 2: enter the number of unduplicated (unique) patients served between January 1 and December 31, 2024, who were 18 years old and older who had an eligible surgery or procedure within the OAS CAHPS eligible range (i.e., CPT- 4¹ code in the 10004 - 69990 or 92920 - 93986 range or the following G-codes: G0104, G0105, G0121 or G0260). Note that a list of excluded CPT codes that should not be included in the count can be found in the Protocol and Guidelines Manual Appendix P, available on the OAS CAHPS website.

  Count all patients regardless of payment method (CMS, insurance, or other method of payment).

  To determine the number of unduplicated or unique patients served, count each patient only once regardless of the number of surgeries or procedures they received during the specified 12-month period.

• Step 3: Of the patients included in the count in Step 2, enter the number of patients who fall into each of the categories in Steps 3a through 3g. These patients are not eligible to be included in the OAS CAHPS Survey. Do not include a patient in more than one category. For example, if a patient who was served between January 1, 2024 and December 31, 2024, was released to hospice, but you know that that patient is deceased, you would include that patient in the count of patients known to be deceased but not in the count of those discharged to hospice. For Step 3f.2, you must provide a brief description of the relevant state laws/regulations and the number of affected patients until all patients entered in Step 3f.1 have been accounted for.

1.	Enter 6-digit or 10-digit CMS Certification Number (CCN):
	ASCs enter the National Provider Identifier (NPI):
	Confirm the facility name:
2.	Enter the TOTAL number of UNDUPLICATED (unique) patients served between January 1 and December 31, 2024, regardless of payment method, who were 18 years old or older and who received a surgery or procedure in the OAS CAHPS eligible range (see instructions above for eligible procedures)
3.	Of the patients included in Step 2, enter the number of patients who fall into the following categories. Do not include a patient in more than one of the following categories.
	a.	Number of patients who were known to be deceased as of the day of your count
	b.	Number of patients who were discharged to hospice or a psychiatric hospital following their surgery or procedure
	c.	Number of patients who reside in a nursing home
	d.	Number of patients who are prisoners
	e.	Number of patients who do not have a U.S. domestic mailing address
	f.1	Number of patients who have a condition or illness for which the state in which the patient resides has regulations or laws restricting the release of patient information for patients with those conditions
	f.2	In the text box below, provide a brief explanation that includes the relevant state laws/regulations that apply to all patients you have entered in step f.1 above.
	g.	Number of patients who at their initial contact with the facility, on their own initiative, requested that the facility protect their identity (i.e., they said that the facility may not release their name or any contact information to anyone other than the facility personnel). If you enter a number in this field, you may be requested to provide documentation to CMS.
