The number of personal injury claims made to the Injuries Resolution Board last year rose 10%.
However despite the increase, the total volume of claims at 20,263 remained 35% lower than in 2019.
Motor liability claims were up 14% in number compared to a year earlier, public liability claims rose 3% and employers liability claims edged up just 1%.
In total, awards worth €170 million were made, the organisation's annual report shows.
That is up €29m on the previous year, but still down 38% from the €275m awarded in 2019, due to the lower volumes.
The median award value overall was €11,650, a 37% reduction on levels in 2020, when they were last made using the old Book of Quantum system.
The median value of motor liability awards was down 41% on 2020 levels at €10,692, while the median value of public liability awards was 40% lower at €20,396.
The overall rise in claims was driven by a 14% increase in road traffic claims last year.
"We are seeing more stabilisation in relation to the motor claims, we're only seeing 2% growth so far this year," said Rosalind Carroll, CEO of the Injuries Resolution Board.
"In terms of our claims regarding fatal injuries, they went up by 37% and when we look specifically at road deaths, what we can see is that about 50% of those are vulnerable road users and I think it's important to highlight that. They included pedestrians, motor cyclists and cyclists, so people who don't have the protection of a car."
The median value for an employers’ liability award was €16,531, a reduction of 29% on three years ago.
"It is also important to say that employer liability and public liability, they were fairly stable, so we didn't see increases across those," Ms Carroll told Morning Ireland.

The highest award last year was €691,000, up from €655,000 in 2022.
Consent and acceptance rates were higher, meaning more claims were retained and resolved by the Injuries Resolution Board in 2023.
71% of respondents consented to the assessment being made by the board, up marginally on a year earlier and the highest rate recorded since it was established.
While 48% of assessments were accepted by both claimant and respondent.
The board estimates that a total of €75m was saved in avoided costs as a result of claims not going to litigation last year.
Claims for fatal accidents did rise, however, by 37% to 115.
Half of all fatal road traffic accident claims in 2023 involved vulnerable road users such as pedestrians, cyclist and motorcyclists, underscoring the heightened vulnerability of such groups on our roads.
Just under 70% of all fatal road traffic accidents affected males and close to half involved people aged under 30 years old.
The average length of time it took for the board to assess a claim was 11.3 months.

A second report issued by the board shows that in the second half of 2023, the percentage of severe or serious injury awards was more than twice that of 2021, increasing from 2% to 5% of claims.
At the same time, the percentage of claims for minor injuries reduced from 86% to 76%.
"The impact of the introduction of the Guidelines can be seen from our reports," said Ms Carroll.
"It is important when looking at changes in claims values in Ireland, not just to focus on average awards values but the decline in the number of claims being made, with total claim volumes remaining 35% lower than in 2019 and the total value of compensation awards now €105 million lower than 2019."
The Alliance for Insurance Reform said it was clear from the data that the Personal Injury Guidelines are having an impact.
But it also questioned where all the savings are going as premiums are not falling.
"Assessment values are €105 million lower than in 2019 and €75m was saved in litigation costs last year alone," said Tracy Sheridan, a board member of the Alliance.
"These are not small sums of money and yet for many businesses and consumers out there, premiums continue to rise.
"This is a fairness issue and at a time when the cost of business is so high, we desperately need to see savings being passed on."
Minister of State Dara Calleary said that the results are a testament to the effectiveness of collective efforts to create a more stable insurance environment for the benefit of the economy and society alike.
"I want to see all this transformative change passed onto business and consumers via reduced premiums," he said.
Reacting to the new data Insurance Ireland said it shows continued positive trends in the area of claims amounts.
"They once again illustrate that the work on insurance reform by Government with industry is making a real impact," said Moyagh Murdock, CEO of Insurance Ireland.
"Nevertheless there are some clouds on the horizon, which cannot be overlooked, such as the level of costs associated with litigation, which have not decreased in line with the overall reduction in awards, and significant increases in motor damage costs."
"The Injuries Resolution Board is one part of the claims environment and it is important to keep the bigger picture in mind."
"Successive NCID reports have also shown that litigated channels still account for the vast majority of claims costs. This is despite the fact that litigation is slower and doesn’t deliver better outcomes for claimants, with most of the additional cost going to legal fees."
"This underlines the importance of the strengthened role of the Injuries Resolution Board to increase settlements though mediation and without unnecessary litigation."
