Combined ratings / 90% and 70%
38 CFR 4.25 Table I · checked 2026-10-20
90% and 70% VA rating combined
A 90% and a 70% rating combine to 97, which VA rounds up to 100%. The 70% is not added to the 90%: it takes 70% of the 10% efficiency the first rating leaves, which is 7 points. At 100% a veteran alone receives $3,938.58 a month and a veteran with a spouse $4,158.17.

The arithmetic, step by step
- Order by severity: 90% first, then 70%.
- After the 90% rating, 10% efficiency is left. The 70% rating takes 70% of that: 70 × 10 ÷ 100 = 7.
- 90 + 7 = 97. That is the figure printed in Table I at row 90, column 70.
- Round once to the nearest 10, values ending in 5 going up: 97 becomes 100%.
Because 97 ends in 7, it rounds up, so this pair is rated 3 points above its Table I value. The extra points exist only in the rounded rating: if a third disability is added later, VA combines it with 97, not with 100, because intermediate values are never rounded.
Added together, the two ratings would make 160. VA's method gives 100, 60 points less. The gap grows with the size of the ratings, because each later rating works on a smaller remainder.
What 100% pays
At 100%, VA's table effective December 1, 2025 pays $3,938.58 a month to a veteran alone, $4,158.17 with a spouse, and $4,318.99 with a spouse and one child under 18. Compared with 90% alone ($2,362.30), the pair adds $1,576.28 a month for a veteran with no dependents. The 100% pay page lists every dependent row.
If a third rating is added
A third 10% rating would combine with 97, not with 100: 97 and 10 give 97, rated 100%, no change in the rating. This pair is already at the top of the scale.
On the numbers alone this pair meets the schedular threshold for a total rating based on unemployability in 38 CFR 4.16(a): one disability rated at least 60%. Meeting the percentages is only the start; VA must also find that service-connected disabilities prevent substantially gainful work. See the TDIU guide.
If the two ratings are on paired limbs
When the 90% and the 70% are on the left and right leg (or both arms), 38 CFR 4.26 adds a bilateral factor: 90 and 70 combine to 97, plus 10% of that gives 107, rated 100%. Here the factor raises the exact value but not the rounded rating, which stays at 100%; it can still matter once more ratings are combined. The bilateral factor guide has the full rule.
Conditions that are rated at 90% and 70%
Diagnostic codes on this site with a 90% level include Hip replacement (DC 5054). A 70% level appears in PTSD, Hip replacement, Carpal tunnel (median nerve), Upper radicular group (C5-C6 nerves).
38 CFR 4.71a, diagnostic code 5054, Hip replacement, 90%: “Following implantation of the prosthesis, with painful motion or weakness such as to require the use of crutches.”
38 CFR 4.124a, diagnostic code 8510, Upper radicular group (C5-C6 nerves), 70%: “Complete paralysis: all shoulder and elbow movements lost or severely affected, hand and wrist movements not affected.”
Criteria summarized from the rating schedule; each condition page links to the regulation.
Other pairs
- 90% and 80%: 98, rated 100%
- 90% and 60%: 96, rated 100%
- 80% and 70%: 94, rated 90%
5 other pairs also round to 100%: 90+90, 90+80, 90+60, 90+50, 80+80.

Rating Ledger is not part of VA and does not file or decide claims. Amounts are VA's published monthly rates effective December 1, 2025 for a veteran, before any deduction or special monthly compensation; ratings follow 38 CFR 4.25 and 38 CFR 4.26. Last checked 2026-10-20. Only a VA rating decision sets a rating or a payment. See the methodology.
