Letters after the name denoting Privy Counsellors and Crown appointments follow immediately behind Orders and Decorations conferred by the Crown.

They are arranged in the following order:

Privy Counsellor (PC)
Aide de Camp to HM (ADC)
Honorary Physician to HM (QHP)
Honorary Surgeon to HM (QHS)
Honorary Dental Surgeon to HM (QHDS)
Honorary Nursing Sister to HM (QHNS)
Honorary Chaplain to HM (QHC)

In a social style of address for a peer who is a Privy Counsellor it is advisable that the letters PC should follow the name. For all other Members of the Privy Council the pre-fix 'Rt Hon' before the name is sufficient identification.

As the other appointments to the Crown (QHP, QHS, etc) are held for a limited period only, they are not always used by recipients.
