Q: What is the procedure code for instilling fluorescein into the eye to check for corneal abrasions with the Wood’s lamp?Ī: The fluorescein stain application alone is not a billable code. If you are doing the “well” visit and are also addressing those other issues (and have some HPI and A/P for those issues) - then that is when you bill both the wellness CPT code and the sick visit CPT code (i.e.99393, 99213-25) and the two types of ICD-10 codes, Z00.121 and H66.41 (OM right ear for example). Regardless of how other issues arise - you report the additional specific diagnosis codes with the Z00.121. These can be either diagnoses or signs and symptoms encountered during the visit, or other issues addressed during the encounter such as pre-existing problems or complaints. The Z00.121 codes are used to report a well-child visit with abnormal findings. Q: When do I use ICD-10 codes Z00.121 instead of Z00.129?Ī: You use a Z00.129 (Child well without abnormal findings) when you aren’t either dealing with or reporting any other problems along with the well visit. If you know what the BMI is you should be able to assign it to either E66.01, E66.3 (overweight) or E66.8 (other obesity). You’d only use this if you didn’t know the BMI or the reason for it.
It’s likely you should not be using E66.9. So the E codes loosely map to specific BMIs. To report specific BMIs in addition to the E codes use code Z68.xx. This table would give you E66.01 for BMIs over 40. E66.9 is unspecified obesity.Ī range of BMIs can be assigned to various categories of obesity: Can you clarify when to use each of these codes?Ī: The E codes E66.01 and E66.9 are used to describe various types of obesity, in words.Į66.01 is morbid (severe) obesity from excess calories. She has a laminated cheat sheet that says E66.9 if for BMIs 30-39 and E66.01 is for BMIs>40. We have been coding E66.9 for Body Mass Indexes (BMIs) between 30-34 and E66.01 for BMIs>35. Q: One of our physicians is getting conflicting information regarding the ICD-10 codes E66.01 and E66.9.
