Hours billed per day

Medicaid billing converted into hours of hands-on care per day. The lower bound counts one unit per claim line and needs no price; the other two divide dollars by a unit price, the conservative one at 1.5 times the price. The clinician on the claim may be a supervisor under state rules, so billing organizations are counted too.

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
90832	Psychotherapy, 30 minutes	$461K	37%	$134	$59 (top 5% from $239)	88th percentile
90791	Psychiatric diagnostic evaluation	$338K	27%	$107	$105 (top 5% from $228)	53rd percentile
99238	Hospital discharge day management, 30 minutes or less	$198K	16%	$59	$48 (top 5% from $80)	70th percentile
99231	Subsequent hospital care with straightforward or low level of medical decision making, per day, if using time, at least 25 minutes	$165K	13%	$75	$37 (top 5% from $103)	87th percentile
90792	Psychiatric diagnostic evaluation with medical services	$56K	5%	$101	$112 (top 5% from $313)	43rd percentile
99221	Initial hospital care with straightforward or low level of medical decision making, per day, if using time, at least 40 minutes	$13K	1%	$73	$50 (top 5% from $194)	78th percentile

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
90791	Psychiatric diagnostic evaluation	83	70	$9K	$280	$142	2.0x	1.9x (90th percentile 3.6x)
99231	Subsequent hospital care with straightforward or low level of medical decision making, per day, if using time, at least 25 minutes	204	70	$7K	$85	$46	1.8x	2.4x (90th percentile 4.0x)
99238	Hospital discharge day management, 30 minutes or less	85	68	$5K	$152	$75	2.0x	2.6x (90th percentile 4.7x)

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.
