Skilled Nursing vs. Long-Term Acute Care Hospital: What Is the Difference?
Both are post-acute care settings — but long-term acute care hospitals serve a much sicker patient requiring extended hospital-level medical management that skilled nursing cannot provide.
Most families have heard of skilled nursing facilities, but long-term acute care hospitals (LTACHs) are less familiar — and they serve a very different patient population. LTACHs are hospital-level facilities for patients who need extended acute medical care (typically 25+ days) that is too intensive for a SNF but no longer requires the acute hospital resources of a general hospital.
The Bottom Line
The vast majority of post-hospital patients go to skilled nursing facilities — LTACHs serve a narrow population of the most medically complex patients who need extended hospital-level care that a SNF cannot safely provide. If a family member is being discharged from an ICU with ventilator dependence, a complex infected wound, or multi-organ involvement that has not resolved, a LTACH is likely the appropriate next step. If the patient is medically stable and needs rehabilitation and skilled nursing care, a SNF is appropriate.
Questions Families Ask About This Decision
LTACH admission requires a physician referral and documentation that the patient requires an extended acute care stay due to medical complexity. Medicare has specific criteria for LTACH coverage, including that the patient must be admitted from a hospital (typically an acute care or critical access hospital). The LTACH’s admissions team reviews the clinical record to confirm appropriateness and insurance authorization.
Yes, though they are fewer than SNFs. Major Texas metros have LTACH facilities. Houston has several, including Kindred Hospital Houston and others. Dallas, Austin, and San Antonio also have LTACH options. TIRR Memorial Hermann in Houston specializes in neurological rehabilitation at an IRF level (not technically an LTACH) and is nationally recognized for stroke and TBI rehabilitation.
Some LTACH patients are discharged home with home health services when they have stabilized sufficiently. More commonly, LTACH patients progress to a SNF for additional skilled nursing and rehabilitation before returning to the community. The LTACH social worker typically coordinates the discharge planning process and identifies appropriate next settings.
LTACHs are paid under a separate federal prospective payment system from both acute care hospitals and SNFs. Medicare covers LTACH care for qualifying patients, but coverage criteria are complex and require documentation of medical necessity. After Medicare coverage ends, LTACH care is very expensive — families should understand the coverage period and plan accordingly.
