MDS Discharge Death in a Nursing Home: A2000, F640, and Encoding Requirements

The Administrative Task That Gets Buried by Grief

The resident has been pronounced, the family has been notified, the body has been released to the funeral home, and the room is being cleaned. The clinical team is emotionally spent. And somewhere in the middle of all of this, the MDS coordinator needs to complete a discharge assessment coding the resident's death — with a federal deadline ticking.

The MDS discharge-death assessment is one of the most compliance-sensitive administrative tasks following a resident's death, and it is the one most likely to fall through the cracks.

What the MDS Discharge-Death Assessment Requires

When a resident dies in a skilled nursing facility, the facility must complete an MDS discharge assessment with the discharge reason coded as death. The key item is A2000 (Discharge Date), which records the date the resident was discharged from the facility. In a death scenario, the discharge date is the date of death.

The assessment must also include:

• A0310F (Entry/Discharge Reporting) — coded to indicate this is a discharge assessment, not a routine quarterly or annual
• A2100 (Discharge Disposition) — coded to indicate the resident died in the facility
• The assessment reference date (A2300) set to the discharge/death date
• All required clinical sections completed based on the resident's status prior to death

The F640 Timeline

Federal tag F640 governs MDS encoding and transmission requirements. Under F640, the facility must:

1. Encode the MDS discharge-death assessment within 7 days of the resident's death
2. Transmit the completed assessment to the CMS iQIES system within 14 days of the resident's death
3. Correct any validation errors returned by iQIES and resubmit within the correction window

In practice, this means the MDS coordinator has one week from the date of death to encode the assessment and 14 days to transmit it. Facilities that wait until the deadline are asking for trouble — if validation errors come back, they may not have time to correct and resubmit promptly.

Best practice is to encode the discharge-death MDS as soon as source documentation is available and transmit it promptly, leaving a buffer for corrections.

Common Encoding Errors

Wrong discharge disposition code. The most basic error — coding A2100 as a transfer to the hospital or a return to the community instead of death. This creates a data mismatch that triggers iQIES validation flags and can distort the facility's quality measures.

Mismatched dates. The discharge date (A2000) must match the documented date of death. If the death pronouncement note says the resident died on March 15 but the MDS shows March 16 because the assessment was started the next morning, the discrepancy will surface during a survey.

Incomplete clinical sections. A death assessment still requires clinical data from the resident's last known status. MDS coordinators sometimes leave clinical sections blank because "the resident is dead," but the assessment covers the period up to and including the date of death, and CMS expects complete data.

Late submission. Encoding beyond 7 days or transmitting beyond the 14-day window can create an F640 compliance deficiency.

How F640 Connects to the Death Response Protocol

The MDS discharge-death assessment depends on accurate clinical documentation from the moment of death. The pronouncement note, the notification timeline, the medication records, the final vital signs — all of this feeds into the MDS.

If the charge nurse's death documentation is incomplete or contradictory, the MDS coordinator has to chase down corrections under deadline pressure. If the social worker did not document family notifications, the MDS may be missing required contact data. Every gap in the death response protocol creates a downstream data quality problem.

The most reliable way to prevent F640 deficiencies is to build MDS notification into the death response workflow. The charge nurse completes the pronouncement and documentation; the unit secretary or supervisor triggers a notification to the MDS coordinator within 24 hours; the MDS coordinator begins the assessment with complete source documentation.

The Nursing Home Staff — Family Communication After Death toolkit includes documentation templates designed to capture every element the MDS coordinator needs — so the discharge-death assessment can be completed accurately the first time, without chasing missing data across multiple departments.
