Which Medicare Part D formularies changed this month? Drugs added or dropped, tier, prior-authorization, step-therapy and quantity-limit changes and plan premium changes, computed by Distill from CMS’s monthly formulary files. Change records between consecutive monthly CMS Part D formulary files of a plan year: a drug (RxCUI) added to or dropped from a formulary, its tier, prior authorization, step therapy or quantity limit changed; a plan added or dropped, its premium, deductible or formulary changed. Each record cites the sha256 of both files. Pages of up to 100, oldest first; pass next_cursor back as cursor. Updated monthly. Price: $0.05 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: Freshness only (the plans and terms are read from the CMS file deterministically): 1 until 45 days after the served file’s date (CMS posts one a month), then halving every 30 days. Medicare Part D formulary and plan data as of the CMS public use file’s date (file_date), processed by Distill; the Medicare Plan Finder (medicare.gov/plan-compare) may have newer information. Not enrollment, coverage or medical advice; confirm with the plan. See /terms.

Which Medicare Part D plans in this county cover this drug, at what tier and cost? Every PDP and Medicare Advantage drug plan with tier, prior authorization, step therapy, quantity limit, premium and copay, plan years 2026 and 2027, computed by Distill from CMS’s monthly formulary files. From CMS’s monthly Part D formulary public use file: every stand-alone (PDP) and Medicare Advantage drug plan sold in the county (by SSA county code, or state and county name), whether its formulary covers the drug (RxCUI, or the NDC the file lists), and on what terms: tier, prior authorization, step therapy, quantity limit, negotiated-drug flag, the plan’s premium and deductible, and the 30-day initial-coverage cost sharing for that tier at each pharmacy type. Covering plans come lowest tier first, then lowest premium. Pass plan_year=2027 for open enrollment. Employer and PACE plans are not in the file. Updated monthly. Price: $0.02 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip".

How does Medicare’s allowed amount for one code vary across the US? Physician Fee Schedule amounts in all 109 Medicare localities (or one state’s) with the national amount and range, computed by Distill from CMS’s RVU and GPCI files. The facility and non-facility allowed amounts (non-QP) for one code in each of the 109 Medicare payment localities, or those of one state, with the national amount (all GPCIs 1.0) and the range: how much the same service is allowed for across the country.

What changed in hospital prices this week? Colorado hospital price, payer-rate, file and status change records, computed by Distill by diffing the hospitals’ price-transparency files. Change records from diffing consecutive weekly builds: a hospital republishing its file (source raw_sha256), items and payer rates that appear, disappear or change price, a hospital’s status or file date changing, and the canonical payer of a payer/plan name changing. Keys: source `<source_id>`; hospital `<hospital id>`; item `<source_id>|<type>|<code>|<setting>|<billing_class>|<modifiers>`; rate `<item key>|<payer name>|<plan name>|<methodology>` (names as the hospital writes them; one rate per methodology, empty when none is given); plan `<payer name>|<plan name>`. Money is integer micro-USD (unit usd_micro). Each record cites the sha256 of the file versions it came from. Pages of up to 100, oldest first; pass next_cursor back as cursor. Updated weekly. Price: $0.05 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: Change records are diffs of consecutive serving DBs, computed deterministically; confidence is the feed’s freshness only: 1 within 14 days of the newest build, then halving every 30 days. Posted standard charges from hospital machine-readable files (45 CFR 180): posted rates, not a quote; not medical or financial advice. What you pay depends on your plan, your care and the hospital. See /terms.

How do these hospitals compare on price for one procedure? Cash, gross and negotiated-rate statistics for a CPT, HCPCS or MS-DRG code at up to 10 Colorado hospitals, normalized by Distill from their price-transparency files. For each named hospital: whether it posts the code, and over its items for the code (only those without modifiers when it posts any, so a professional -26 or bilateral -50 line does not skew the row) nearest-rank statistics of its gross charges, discounted cash prices and negotiated dollar amounts across payers and plans, the range of negotiated percentages, the de-identified minimum and maximum, and the number of payers. The same filters as hospital.prices. Hospital ids come from hospital.prices (or pass a CMS certification number). Not charged when none of the hospitals is known. Updated weekly. Price: $0.02 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: Mean over the returned rows (each rate; an item with no rate counts once) of normalize × quality × freshness. Normalize: the stored per-rate normalize confidence (payer canonicalization: rule 1, model 0.9, fallback 0.6; rate basis for rates with no dollar amount: rule 1, model 0.9, fallback 0.75; 1 for an item with no rate). Quality of the MRF: 1 valid against the v3.0 schema, 0.85 parsed with conformance errors, 0.7 parsed only after header repair. Freshness: 1 while the MRF’s last_updated_on is at most 365 days old, then halving every 180 days (0.5 with no date), times 1 within 14 days of our fetch, then halving every 30 days. Rows are each hospital’s items for the code as compared. Posted standard charges from hospital machine-readable files (45 CFR 180): posted rates, not a quote; not medical or financial advice. What you pay depends on your plan, your care and the hospital. See /terms.

What has each insurer negotiated for a procedure in this area? Negotiated prices by canonical payer (Aetna, Cigna, UnitedHealthcare, Medicare Advantage, …) and plan type for one code near a Colorado ZIP, computed by Distill from hospital price-transparency files. Every payer’s negotiated dollar amounts for the code at the hospitals within the radius, grouped by canonical payer_id (the stable id behind the many ways hospitals write a payer’s name), plan type and methodology (a per diem and a case rate are never pooled): how many hospitals and rates, and nearest-rank statistics. Payers with the most hospitals first. Percentage-only rates are left out (they have no dollar amount; hospital.prices shows them). The payer_ids here are what the payer filter of hospital.prices and hospital.compare takes. Updated weekly. Price: $0.02 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: Mean over every rate in the payer rows returned of normalize × quality × freshness, with the same factors as hospital.prices (normalize: the stored per-rate payer canonicalization confidence, rule 1, model 0.9, fallback 0.6; quality: 1 valid v3.0, 0.85 with conformance errors, 0.7 after header repair; freshness: 1 while last_updated_on is at most 365 days old, then halving every 180 days, times 1 within 14 days of our fetch, then halving every 30 days).

What does a procedure cost at hospitals near this ZIP? Cash price, gross charge and every insurer’s negotiated rate for a CPT, HCPCS or MS-DRG code at Colorado hospitals, normalized by Distill from the hospitals’ federally required price files. From the machine-readable standard-charge files hospitals must publish (45 CFR 180), parsed and normalized: for each hospital within the radius that posts the code, nearest first, the gross charge, the discounted cash price, the de-identified minimum and maximum, and every payer and plan’s negotiated dollar amount or percentage (with the v3.0 median, 10th and 90th percentile allowed amounts), payers canonicalized to a stable payer_id. Filters: payer, plan type, plan name text, setting, billing class. A summary gives nearest-rank statistics over the hospitals returned. Served states: Colorado. An area with no hospital posting the code answers 404 and is not charged. Updated weekly. Price: $0.02 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: Mean over the returned rows (each rate; an item with no rate counts once) of normalize × quality × freshness.
