Multiturn Conversations and Prompts for Medical Insurance

Data Characteristics for This Category

Medical insurance access data primarily originates from policy documents, drug/device catalogs, payment standards issued by the National Healthcare Security Administration and provincial/municipal medical insurance departments, and registration application materials submitted by enterprises. This data updates frequently. National-level policies typically adjust annually, while local regulations may update quarterly or irregularly. Document formats vary, including policy texts in PDF, drug catalogs in Excel, and enterprise application guidelines in Word. Policy documents have complex structures, containing multiple levels such as clauses, attachments, and interpretations. Drug catalogs present standardized fields like generic drug name, dosage form, specifications, medical insurance payment scope, reimbursement category, and limited payment conditions. Units involve milligrams (mg), international units (IU), and Yuan/unit. Some fields may have multiple aliases or abbreviations.

Constraints Imposed by These Characteristics on Multiturn Conversations and Prompts

The high update frequency of medical insurance access data requires the knowledge base to have an efficient incremental update mechanism. This prevents multiturn conversations from generating inaccurate responses based on outdated information. The complexity of document structures, especially the multi-level and cross-referenced policy documents, challenges the precision of RAG retrieval. This necessitates fine-grained text chunking and metadata management. Standardized but aliased fields in Excel catalogs require prompt design to recognize and associate different expressions, ensuring accurate matching of query intent. Furthermore, the precise extraction of critical information, such as medical insurance payment scope and limited payment conditions, directly impacts the quality of decision support in multiturn conversations. Any misinterpretation of units or conditions can lead to significant deviations. Therefore, multiturn conversations need to repeatedly confirm key numerical values and limited conditions, and trace them back to the original document source.

Configuration Settings

Configuration Item	Suggested Value	Rationale
`maxContext`	`8000 tokens`	Balances long policy document context with multiturn conversation history, preventing information loss.
`Chunk size`	`500 characters`	Adapts to the average length of policy clauses, reducing semantic fragmentation of individual segments.
`Recall count`	`Top 10 entries`	Increases coverage for complex queries, enhancing the chance of retrieving relevant information.
`Similarity threshold`	`0.75`	Filters out low-relevance results, improving retrieval quality and reducing noise.
`Rerank result count`	`5 entries`	Refines the information presented to the language model, focusing on core relevant content.
`retry_count`	`3 times`	Addresses occasional network fluctuations or transient errors from external services.

Common Pitfalls

Incorrect citation or interpretation of medical insurance policy clauses during conversations. This occurs due to outdated knowledge base content or failure to retrieve the latest document version during retrieval.
Incomplete or missing critical numerical information in the limited conditions returned by the system when a user queries specific drug payment conditions. This happens because the original document chunking granularity is too coarse, leading to truncation of important fields.
The chatId field is not correctly passed or is ignored by backend logs during automated submission of application materials. This prevents the association of conversation context, treating each interaction as a new session.

Verification of Configuration

Conduct multiturn questions on recently updated medical insurance policies. Check if the answers accurately cite new policy content and provide document sources.
Randomly select drugs from the medical insurance catalog. Query their payment scope, reimbursement category, and limited conditions. Verify consistency between system answers and official catalog data.
Simulate a registration application material filling scenario. Modify and confirm key field values in a multiturn conversation. Verify if chatId or similar session identifiers remain valid in backend logs.
For complex queries, such as scenarios involving the cross-impact of multiple policies, check the relevance ranking of retrieval results. Ensure highly relevant clauses are ranked prominently.
