You can work 365 days of the year if you want seeing and billing patients. My comment was a caution about overseeing a stable patient that doesn’t need a Saturday/Sunday follow up and had already been seen by primary 5 days that week. Especially with IM on board.
You should still have a reason to go see and bill a patient. If you’re as efficient and quick as you said, did you really have to go in and charge the patient to get the job done? Could you have just discussed with nursing? I’ve made it by with mostly doing only admissions on call weekends + seeing a d/c or sick patient for follow up as needed. Otherwise they are mostly fine. Doesn’t mean you can’t do it, but was just my opinion.
I think a main reason I said that in your case was that you are being paid a flat rate. So why not just see the admissions and triage any follow ups? You have no financial incentive to see everyone from what you said. So why work harder for the same money?
Theoretically you can get in trouble or denied for over billing. For instance, If your PCP told you to come in every week or even every month for no reason, your insurance would get upset and so would you for all the charges. Once IRF patients are stable then the concept is similar. Patients don’t like getting a charge for some random Doc they never saw before stick their head in the door for a few minutes. Insurance companies also may not pay for it unless you had a good justification to see them. As a covering doc, you are probably not going to get in any trouble if you round Sat/Sun. You will probably never even know about any insurance denials since you aren’t collecting. On another standpoint, you may also be setting up your partner to not see anyone not necessary on Monday since they were billed all weekend. That could hurt your partners WRVUs.
If you work somewhere that has a policy that every patient needs to be seen 7 days a week then ignore the above. The hospital takes any liability.
