How many days does a physician have to certify a resident's medical necessity for nursing home care after admission?

• A. 10 days
• B. 40 days
• C. 5 days
• D. 20 days

Answer: (D)

The key idea is the deadline for documenting medical necessity after a resident enters a nursing facility. After admission, the attending physician must certify that ongoing skilled nursing or rehabilitative services are medically necessary within 20 days. This certification supports continued eligibility for coverage (Medicare/Medicaid) and ties the level of care to an identified medical need rather than custodial care alone. Shorter windows (like 5 or 10 days) wouldn’t allow enough time for a proper initial assessment, while a longer window (such as 40 days) could delay essential coverage and accountability. Therefore, 20 days is the standard period for this certification.
