Understanding Potential New Alignments (PNA)

How is PNA calculated?

The Potential New Alignments are computed by taking the CMS Submission file (unique MBIs only) and excluding already-aligned beneficiaries as well as any previously submitted alignments.

Why is PNA important?

It is the most relevant metric to share with leadership to inform forecasting/projections. The Actual New Alignments (A0, as reported by CMS) varies by network, but tends to come in at ~65% * PNA for Standard ACOs and ~40% * PNA for High Needs ACOs

Why is there a difference between the number of Completed SVAs and the number of rows in the submission file?

Per CMS guidance, Mabel only submits the most recent Completed SVA per MBI, so multiple completed forms from a beneficiary lead to only one row. Moreover, Mabel filters the submission list for SVAs that do not appear in a previous SVA response file, again per CMS guidance.
