Correct 1099R Code for in-kind distribution of annuity contract from qualified plan?

[Guest CTBenefitsLaw]

A Participant is set to take a distribution from 401(k) plan, and elects to receive an annuity form of distribution. Presumably per plan document, trustee purchases an annuity with the Participant's account balance, then transfers the annuity contract to the Participant. Pretty sure that this is reported on Form 1099R, but not sure what code to assign the distribution to report it on the 1099R. Any thoughts?
