Procedures billed

The specific codes behind the dollars. Medicaid figures come from T-MSIS (2018 to 2024) and are compared with every other provider billing the same code; Medicare figures come from the 2024 physician and supplier file and compare this provider's submitted charge with what Medicare allowed, against the usual ratio for that code.

Medicaid, largest codes

code	what it is	paid	share	per patient-month	typical	rank among providers
99213	Established patient office or other outpatient visit with low level od decision making, if using time, 20 minutes or more	$4K	100%	$69	$44 (top 5% from $110)	too few months to rank

Medicare Part B 2024, largest codes

code	what it is	services	beneficiaries	paid	submitted per service	allowed per service	charge to allowed	usual for this code
99222	Initial hospital care with straightforward or low-level medical decision making, if using time, at least 55 minutes	62	60	$6K	$331	$122	2.7x	2.7x (90th percentile 4.4x)
99232	Subsequent hospital care with moderate levelof medical decision making, if using time, at least 35 minutes	77	47	$5K	$194	$75	2.6x	2.6x (90th percentile 4.3x)
99204	New patient office or other outpatient visit with moderate level of medical decision making, if using time, 45 minutes or more	16	16	$2K	$413	$126	3.3x	2.4x (90th percentile 3.9x)

A submitted charge many times the allowed amount is common and lawful; it matters when it is far above what other providers submit for the same code.
