Hospice Post-Mortem Visits – When to Report the PM Modifier

Hospice agencies are required to report post-mortem visits, precisely until midnight, on the Date of Death (DOD), using the Post-Mortem (PM) Modifier when billing. The DOD is defined as the date reported on the death certificate.

Reporting the post-mortem visit-

  • Hospices shall report visits and the length of visits (rounded to the nearest 15-minute increment), for nurses, aides, social workers, and therapists who are employed by the hospice, that occur on the date of death, after the patient has passed away (until midnight).
  • Post-mortem visits occurring on a date after the date of death are not to be reported.
  • Hospices shall report visits that occur before death on a separate line from those which occur after death (the lines for services performed after death require the PM modifier).

Examples

  • Assume that a nurse arrives at home at 9 p.m. to provide routine home care (RHC) to a dying patient, and that the patient passes away at 11 p.m. The nurse stays with the family until 1:30 a.m. The hospice should report a nursing visit with eight 15-minute time units for the visit from 9 p.m. to 11 p.m. On a separate line, the hospice should report a nursing visit with a PM modifier with four 15-minute time units for the portion of the visit from 11 p.m. to midnight to account for the 1-hour post-mortem visit.
  • If the patient passes away suddenly, and the hospice nurse does not arrive until after his death at 11:00 p.m., and remains with the family until 1:30 a.m., then the hospice should report a line-item nursing visit with a PM modifier and four 15-minute increments of time as the units to account for the 1-hour post-mortem visit from 11:00 p.m. to midnight.

Reporting Issues to be aware of

When Hospices incorrectly report post-mortem visits using the PM modifier on claims, this can result in errors in the review process and may cause the Service Intensity Add-On (SIA) payment to be applied incorrectly to the claim(s).
