# ASP Pricing File, Medicare Part B quarterly payment limits (parse revision 2, every CMS revision kept)

`drug_silver.fact_drug_asp_quarterly_v2` · Drugs and formularies · status live · 55,035 rows

Medicare Part B payment limits per HCPCS billing unit, every quarter Q1 2005 onward, parse revision 2 (ASP parser 2.0.0). Each CMS revision of a quarter is kept (cms_vintage_sequence); use WHERE is_current for the latest. The payment limit is 106% of ASP on a two-quarter lag, not the ASP. 2005-2009 limits are the publisher's '$' text parsed exactly; clotting_factor_flag marks clotting-factor codes (a flag, not dollars). Infusion AWP% / DME infusion limit exist 2005-2016 only; Independent ESRD limit 2005 only. asp_pricing_lookup, drug_price_composite and prove_drug_reimbursement_decision read this table from 2026-10-05.

**Grain.** One row per (hcpcs_code, release_quarter, cms_vintage_sequence); among is_current rows (hcpcs_code, effective_period_start) is unique: 55,035 rows = 55,035 keys over 88 quarterly editions, Q1 2005 to Q4 2026 (Athena e3c215d1, f0abf87e).
