How Highmark denies home healthcare — home nursing, home infusion, home pt/ot/slp, home aide, hospital-at-home — and how to counter it

Where Highmark pushes back: 1) 'Plateaued / no improvement — discharge from PT'; 2) 'Custodial — does not require skilled PT'; 3) 'Frequency excessive'.

Counter-arguments that hold up: Cite Jimmo v Sebelius 2013 + CMS Ch 7/8/15 post-Jimmo revisions — Medicare covers maintenance therapy and prevention of decline when skilled service required. Document specific skilled PT task (gait training with progression, fall-prevention strategies, neuromuscular re-education, complex transfer training, post-stroke NDT) that requires PT-level skill. Functional measures (BBS, 10MWT, AM-PAC, FIM motor, mJOA) at admission and current; trajectory or maintained level. POC frequency justified by deficit / response.
