Oxygen Supplement

Provider applied for home care package oxygen supplement for my husband’s supply 24/7.
Oxygen Supplement is $12.10 per day, or $363 per 30 days.
Hire of oxygen and equipment charged to husband $168.25 per month and we were told by Provider that this comes out of his Level 1 Home Care Package.
My questions are …
Does provider receive the full amount of $363 every 30 days?
Should the $168.25 come out of my husbands Level 1 HCP, or is the hire $168.25 dealt with separately to the HCP, and comes out of the Supplement?
Does Provider then receive the balance $194.75?
Thank you for any information.
