Will the updates to the Health Insurance Claim Number (HICN) and social security number (SSN) fields for the 2020 MORs also apply to the 2019 MORs?

Answer:

Yes, for 2019 final reconciliation, the associated MORs will include updates to replace the HICN field with the Medicare Beneficiary Identifier (MBI), and the SSN field has also been replaced by a filler field. Please refer to the November 6, 2019 HPMS memo, “Updates to Payment Year (PY) 2020 Model Output Reports” for additional details on these updates.
