As there is a rise in the use of multimodal large language models (LLMs) for medical response generation, it is necessary to have reliable automated evaluation mechanisms that can assess the quality of model-generated outputs. The MediQA-Eval 2026 shared task focuses on grading AI-generated dermatology and wound care responses using structured human-aligned rubrics. In this work, we explore a zero-shot multimodal LLM-as-a-Judge framework to assess candidate responses across multiple quality dimensions. System performance is evaluated using the official task metrics designed to reflect alignment with human judgments. Our findings provide preliminary insights into the feasibility and limitations of LLM-based evaluators for rubric-guided medical response assessment.

In online forums like Reddit, users share their experiences with medical conditions and treatments, including making claims, asking questions, and discussing the effects of treatments on their health. Building systems to understand this information can effectively monitor the spread of misinformation and verify user claims. The Task-8 of the 2023 International Workshop on Semantic Evaluation focused on medical applications, specifically extracting patient experience- and medical condition-related entities from user posts on social media. The Reddit Health Online Talk (RedHot) corpus contains posts from medical condition-related subreddits with annotations characterizing the patient experience and medical conditions. In Subtask-1, patient experience is characterized by personal experience, questions, and claims. In Subtask-2, medical conditions are characterized by population, intervention, and outcome. For the automatic extraction of patient experiences and medical condition information, as a part of the challenge, we proposed language-model-based extraction systems that ranked $3ˆ{rd}$ on both subtasks’ leaderboards. In this work, we describe our approach and, in addition, explore the automatic extraction of this information using domain-specific language models and the inclusion of external knowledge.
