I have some questions on certain LXXXX codes. We have never had an LXXXX code paid my DMERC-ever. What are the approved dx's to get these paid? I am thinking they have to be diabetes dx's but i'm not sure because we have never billed one of these w/ a diabetes dx. I have no problem with the A5500 or A5513 codes, but these L codes I can't seem to figure out! FYI, we had some issues getting our provider # established w/ DMERC, so we have just recently began getting payments for dos's that go back to 06 and 07! So, basically I am just being able to figure out what is approved and what is not. Feedback on ANYTHING DMERC would be so helpful!! Thank you in advance!!!
