MELD Score Calculator
MELD estimates 90-day mortality risk in adults with chronic liver disease. Used for liver transplant prioritization.
MELD Score
Interpretation (90-day mortality)
- <10: ~1.9%
- 10–19: ~6%
- 20–29: ~20%
- 30–39: ~52%
- ≥40: ~71%

Frequently asked questions
What does MELD ≥15 mean?
Generally accepted threshold for liver transplant evaluation referral. Below 15, transplant survival benefit is uncertain; above 15, transplant typically improves outcomes.
Is MELD-Na different?
Yes. MELD-Na adds serum sodium to the calculation, giving better mortality prediction in hyponatremic patients. Many transplant centers now use MELD-Na or MELD 3.0.
How accurate is MELD for non-transplant decisions?
MELD was validated for transplant prioritization. It's also used for prognosis in cirrhosis, TIPS evaluation, and pre-operative assessment in liver disease, though performance varies by context.
