Medicare Coverage & Payment
- CMS short descriptor: Pt rec'g rrt
Source: CMS HCPCS Level II release. Coverage codes indicate how Medicare treats the code, not whether a specific claim will be paid; payer policy and documentation still govern.
Coding context
Guidelines, coding notes, decision aids, relationships (with MS-DRG and CCSR classification), hierarchy, HCC, coverage and the context map: what a coder reaches for after the core. Each section names whether it is official source data, a MedCoder-derived relationship or MedCoder editorial.
Contextual Map
Every relationship of M1199 in one view: hierarchy, official tabular instructions in both directions, clinical classification, risk adjustment, MS-DRG participation, index terms and change history — each edge carrying the CMS source it derives from.
