Adjusting formula with nested IF and/or functions

I am looking to create a formula to help me determine if a dose of a medication is appropriate based on a few variables. the columns I have are the following:
J2=creatinine clearance
L2=type of renal replacement therapy (has three possible values: IHD, SLED, or CRRT)
M2=dose (has two possible values: 2.25 or 3.375)

Based on the criteria the dose is appropriate in the following situations:
J2>20 OR L2=CRRT AND M2 = 3.375,
J2<20 OR L2=IHD OR L2 = SLED AND M2=2.25.

This is the formula I have so far:
=IF(AND(OR(J2>20,L2="CRRT"),(M2=3.375)),"YES",IF(AND(OR(J2<20,L2="IHD",L2="SLED"),(M2=2.25)),"YES","NO"))

It seems to be working except when J2>20,L2=IHD and M2=3.375 the output is that the dose is appropriate when it shouldn't be, as if L2=IHD M2 has to equal 2.25 for the dose to be appropriate. Would greatly appreciate any help or advice!

I't quite ambiguous because there's no wrong about your rules and the case

J2>20,L2=IHD and M2=3.375 the output is that the dose is appropriate when it shouldn't be

First let's separate the logic of the formula

J2>20 OR L2=CRRT
AND
M2 = 3.375,

the case is
J2>20 (MATCH) , L2=IHD (NOT MATCH)
AND
M2 = 3.375 (MATCH)

So, when 1 (match) of OR logic meet 1 (match) AND logic the result should be true/yes

Although the L2 is not match but the J2>20 is match, which fulfill the OR logic

and the AND logic is suitable too because
M2 = 3.375

I suggest you to add more rules like why the case above should not appropriate when the case is met the criteria that result to YES
I guess you missed something about the OR and AND logic that makes the case not meet the criteria

Edit : I missed something, did you mean this?
J2>20
OR
L2=CRRT AND M2 = 3.375

instead of

J2>20 OR L2=CRRT
AND
M2 = 3.375
