calculate_combined_rating
Use this when a veteran has two or more VA disability rating percentages and wants the combined rating. Applies the 38 CFR 4.25 Combined Ratings Table procedure: pairwise combination in severity order, whole-percent rounding after each step, then conversion to the nearest 10. Returns combinedRating as an object holding both figures under their own names: rounded is the rating after that conversion, raw is the Combined Ratings Table value before it. The arithmetic for each step comes back alongside them. The optional bilateral argument tags the ratings that affect both arms or both legs; when it is supplied and one pair has a compensable rating on each side, 38 CFR 4.26 applies to those ratings first: they combine with each other, 10 percent of that value is added rather than combined, and the result enters the 4.25 combination as one disability. Without that argument no bilateral factor is applied. The 38 CFR 4.26(d) comparison across eligible groupings is exhaustive here for up to 16
compare_rating_criteria
Use this when a veteran names a VA diagnostic code and wants the rating criteria for it. Returns the VASRD criteria on file for that code at every tier, highest percentage first, with the condition name, body system and 38 CFR reference, so the findings each tier requires can be read side by side. It takes a diagnostic code rather than a condition name. A code that 38 CFR 4.71a, 4.73 or 4.124a rates in two columns, one for the dominant arm (Major) and one for the non-dominant arm (Minor), returns the regulation's own table and an empty tiers list: schedule is that table as published, with schemaVersion, variant and provenance (the eCFR edition date and the SHA-256 of the source text), every row carrying both published percentages, and scheduleText renders it with its headings, footnotes and the notes whose stated scope includes the code. Notes printed in the same table whose applicability is not established are quoted in a separate labelled section; placement alone does not establish t
analyze_rating_gap
Use this when a veteran gives a condition name and the percentage currently assigned for it, and wants that percentage compared against the VASRD criteria. Returns the tier that matches the current percentage, the next tier above it, and every higher tier on file for that condition, with the criteria each one requires. It reports when the condition is already at the highest documented tier, and when no criteria are on file for that condition name. documentedTiers lists the tier percentages on file for the condition, and currentPercentIsDocumentedTier says whether the percentage supplied is one of them: false means the figure does not correspond to a tier in the criteria on file, which happens when the rating came from a formula or a code this search did not resolve. For a veteran at zero percent, zeroPercentBasis is "documented" when a zero percent row for the code is on file and "unresolved" when the complete tier set could not be established, and zeroPercentUnderFourThirtyOne answers
calculate_rolling_window
Use this when a veteran supplies dates of incapacitating episodes and the question involves the 38 CFR 4.71a formula for rating intervertebral disc syndrome on incapacitating episodes, diagnostic code 5243. Totals the calendar duration of those episodes inside the 12 months ending on a reference date: the window opens the day after the same date one year earlier and closes on the reference date, with both ends counted, so an episode that began exactly 12 months before that date falls outside it by one day. That formula bands on total calendar duration in weeks, so weekend and holiday days inside an episode count, and only periods flagged as bed rest prescribed by a physician count toward a tier. Returns the window, a per-period breakdown, the tier the flagged episodes would support, and a separate employer-leave workday count that plays no part in that tier. Inside ivdsThresholdAnalysis, calendarDaysBelow60PercentThreshold and weeksBelow60PercentThreshold report how far the counted epi
find_secondary_conditions
Use this when a veteran names a service-connected condition and asks what other conditions can follow from it. Returns the records whose own primary condition is the one searched for, each with the strength of the supporting evidence, the medical rationale, key studies, filing notes, the diagnostic codes involved, and the primary condition the record itself names, so a row can be read against the query it answers. Other primary conditions that the search terms reached are summarised separately under relatedPrimaries, with the term that matched and a count, rather than being returned among the rows. Each row carries its provenance: the paragraph of 38 CFR 3.310 the link rests on, the rating schedule section and diagnostic code its evaluation comes from, the eCFR URLs for those sections, and the date the codes and percentages were checked against the rating schedule. That check establishes that a code exists in the schedule and that an evaluation is one the schedule offers for it, which
check_presumptive_eligibility
Use this when a veteran asks whether a condition is presumptively service connected, or which conditions are presumptive for a given exposure or service era. Returns matching presumptive conditions with the service era, exposure type, required service, legal authority and evidence needed for each, and repeats that legal authority in a provenance block on every row, with the date the presumption took effect where one date is true of the whole row; that date can be null for a row that groups conditions added on different dates. At least one of condition, serviceEra or exposureType is required. Filters combine with AND: condition plus exposureType or serviceEra narrows to their intersection, and each filter needs at least one word of three or more characters or the query is refused. A condition description that names a qualifying circumstance, such as a diagnosis that has to come after the qualifying service, states a limit of the presumption rather than a detail beside it. An empty resul
search_legal_authority
Use this when a question calls for the text of a VA rating regulation, the wording of a legal standard, or case law, searched by keyword, by exact citation, or by diagnostic code. Returns 38 CFR rating criteria for matching conditions; doctrine entries quoted verbatim from the regulation, statute or decision they come from, each with pinpoint citations, the date the text was captured, when that text took effect, and the reviewed holdings that construe it; and excerpts from Court of Appeals for Veterans Claims decisions with docket number, case name and relevance score. CAVC decisions are binding precedent for the Board of Veterans' Appeals. The citation parameter takes a section such as "3.310", "38 CFR 3.310(b)" or "38 U.S.C. 5107(b)", and a citation that cannot be read as a section matches nothing rather than being guessed at. A citation on its own is a complete call: query is optional when citation is supplied, and a call carries query, citation, or both. The limit parameter caps re
prepare_cp_exam
Use this when a veteran has a VA compensation and pension examination scheduled for a condition and wants to know what it involves. Returns the examination type and typical length, what the examiner does, the questions examiners commonly ask, the Disability Benefits Questionnaire sections that apply, and records worth bringing. It does not return advice about what to describe, emphasize or omit at the examination. For a condition with a guide on file it also returns the diagnostic code for that condition and where its rating criteria are published, which are what the examiner's findings are scored against; any other condition returns a general exam guide. Educational reference about the examination process. It does not schedule, reschedule or contact VA, and the examiner's findings and VA decide the rating.
lookup_compensation_rate
Use this when a veteran wants the monthly VA disability compensation amount for a given rating percentage and dependent situation. Returns the monthly and annual amounts from the VA compensation rate table in effect, with the rate year and effective date. The rating is read to the nearest 10 percent, and dependents change the amount only at 30 percent and above. Children are counted as children under 18; school-age children 18 to 23, dependent parents and aid and attendance are outside what it models. It gives the published rate for that combination, not what a specific veteran is paid, and it is not a back-pay calculation for a past period.
compute_retroactive_pay
Use this when a veteran gives an effective date and a rating increase and asks what the retroactive amount would be. Returns an estimate of the difference in monthly compensation for each month of the period, with a per-month breakdown, the assumptions behind it, and its own disclaimer. Under 38 CFR 3.31 payment starts on the first day of the month FOLLOWING the month the award became effective, with no exception when the effective date is itself the first of a month, and the period runs through the month of adjudication, which is counted in full. VA rate tables take effect on December 1, so a payment year runs from December 1 through November 30 and December of one year is paid at the next payment year rates. Each month of the breakdown reports the payment year it was paid from (rateYear), that table effective date (rateTableEffectiveDate) and where the table came from (rateSource), and the tables the period drew on are listed once each in rateTables; a published table carries the VA
find_claim_help
Use this when a veteran asks who can help them with a VA disability claim, or when they describe a crisis. The Veterans Crisis Line comes first, in full, when need is crisis, and no other need returns crisis content. Setting urgent true puts the veteran’s first action at the top of routeNow and does not change the crisis routing. Every result carries accredited representation routes: VA accredited Veterans Service Organizations, whose services on VA benefit claims are free, and accredited attorneys and claims agents, who may charge fees only for representation provided after VA issues notice of an initial decision on the claim (38 CFR 14.636(c) and 38 U.S.C. 5904(c)(1)). It also returns the VA Office of General Counsel accreditation search and the VA.gov find a representative tool, the state or territory veterans agency matching a two-letter state code, VA phone numbers suited to the need, the documents worth bringing, and links to the VA forms that need points at. It names no individu
search_guides
Use this when a veteran asks about a VA topic VeteranHQ has written a guide on. Returns the guides whose text matches the query, highest scoring first, each carrying the guide slug, title, summary and public URL, and no body text. The ordering is lexical and deterministic, computed from where each word of the query appears: a match in the guide title scores above one in the summary, a summary match above one in a section heading, and a heading match above one in the body, with an added score when every word of the query appears somewhere and a further one when the whole query appears in a title. Guides tied on score are ordered by slug, so the same query returns the same list in the same order on every call. No model runs and no network call is made. The limit parameter caps how many guides come back, from 1 to 10, default 5. An empty results array means no guide in this library contains any word of the query, which is a fact about the library and not about VA rules or about what VA ho
get_guide
Use this when a slug from search_guides names the guide a veteran needs and the answer should carry what the guide says. Returns the slug, title and summary, the date the facts in it were last verified against its sources, the public URL of the guide on veteranhq.app, the body split into the sections the guide itself defines, each with a heading and its text, and the sources the guide cites, each with a title and a URL. A slug this library does not hold returns a tool error carrying GUIDE_NOT_FOUND, whose message says to call search_guides and use a slug from its results. A guide longer than one result can carry returns the sections that fit, plus omittedSections counting the sections left out and a note stating that count and the guide URL. A single section larger than the whole budget is served shortened at a paragraph or sentence boundary, with truncatedSection naming its heading and the note repeating it, so a section that was cut is distinguishable from one served whole. Those thr
