# Auxilium > Operations software for health care sharing ministries. Prove what share of member contributions reaches medical bills, keep every denial tied to a published guideline, and make sure no member is quietly missed. Auxilium is operations software for health care sharing ministries — organizations where member households share one another's medical costs directly. These are not insurance companies and are exempt from state insurance regulation, including solvency requirements and any statutory obligation to pay a claim on a timetable. ## What it does - **Claims integrity.** Keeps member contributions and disbursements on one ledger and computes a share ratio: of every dollar members contributed, how many cents reached medical bills. Benchmarked against the ACA medical loss ratio (80% individual and small group, 85% large group) — a standard sharing ministries are exempt from, which is why measuring against it voluntarily is meaningful. - **Guideline consistency.** Sharing guidelines are versioned and dated, and each provision declares which denial reasons it authorizes. Denials citing a provision that does not exist, does not authorize the stated reason, or took effect after the member joined are flagged. - **Claim turnaround.** Every claim carries a commitment date. Breaches escalate, and so do claims nobody has opened yet, before their deadline. - **Reference-based repricing.** Reprices facility claims against the Medicare allowable rather than chargemaster rates. - **Narrative Relational Intelligence (NRI).** Scores members on four directions — Cura (care), Onus (case weight and handling), Familia (household complexity), and Fides (engagement) — to surface members at risk of being missed. - **Roster import.** Column inference, validation, and duplicate detection for messy CSV exports, with a full preview before anything is written. ## How scoring works Every score in Auxilium is a sum of named, weighted reasons over the ministry's own data. There is no machine-learning model, no training data, and no learned coefficient anywhere in the calculation. The complete rule set — every code, its weight, and the documented failure it was written from — is published inside the application. Scores are reproducible: the same data and timestamp always produce the same result. ## What it is not - Not insurance and not a health plan. - Not a compliance certification. Health care sharing ministries are exempt from state insurance regulation and no software changes that. - Not fraud prevention. It measures what a ministry's own ledger says and checks decisions against that ministry's own published guidelines. - Not a billing or dues-collection system. It records contributions; it does not collect them. ## Key pages - [Claims integrity](https://auxiliumos.com/claims-integrity): the share ratio, guideline consistency, claim turnaround, and repricing. - [Narrative Relational Intelligence](https://auxiliumos.com/narrative-relational-intelligence): the four directions and the explainable scoring model. - [How it works](https://auxiliumos.com/how-it-works): what a ministry puts in and what comes out. ## Guides - [How to move 5,000 members to a new processor without asking any of them to re-enroll](https://auxiliumos.com/guides/moving-members-to-a-new-processor): Stored cards and verified bank mandates transfer between processors directly, with no member action and no billing gap. What the process actually involves, what it costs in time, and which members genuinely do have to act. - [What a share ratio is, and why it matters](https://auxiliumos.com/guides/share-ratio-explained): Of every dollar members contribute, how much reaches medical bills? How to compute it, what a healthy number looks like, and how to read one honestly. - [How Auxilium scores claims integrity](https://auxiliumos.com/guides/how-integrity-scoring-works): The full method: a starting score of 100, named deductions with stated weights, and a band. No model, no hidden coefficients. - [Why Auxilium does not use AI for scoring](https://auxiliumos.com/guides/explainable-scoring): Every score in Auxilium is a sum of named, weighted reasons. Here is the reasoning behind that constraint, and where AI would be appropriate. - [Moving a member roster without losing anybody](https://auxiliumos.com/guides/csv-import-that-survives-real-spreadsheets): Practical guidance on migrating years of member records out of spreadsheets and legacy systems: what breaks, what to check, and how to dedupe without merging two real people. - [Why claims stall, and how to stop it](https://auxiliumos.com/guides/why-claims-stall): The specific mechanics of a claim going quiet for months, and the process changes that prevent it — most of which are not software. ## Comparisons - [Auxilium vs the spreadsheets you have now](https://auxiliumos.com/compare/spreadsheets): An honest comparison against the tool most ministries actually run on, including the things spreadsheets genuinely do better. - [Auxilium vs a general-purpose CRM](https://auxiliumos.com/compare/generic-crm): What a generic CRM does better, what it cannot model about sharing ministries, and how to decide between them. - [Auxilium vs legacy administration systems](https://auxiliumos.com/compare/legacy-administration-systems): Purpose-built ministry administration platforms are more complete than Auxilium in several areas.
