In advance of official communications from NHS, please see the workaround that has been notified to DWP.
“At present, NHS prescriptions do not have a Tick Box option for someone claiming Universal Credit.
There have been examples of claimants choosing the ESA option and as a result have received a £135 penalty notice.
Until a new print is available claimants on UC should tick option K indicating JSA in payment.
This is the workaround which has been issued to Pharmacies.”
