You should have the right information ready prior to referring to your ICD-9 coding manual to save yourself from trouble.
It always helps to have the right documentation in place. When a patient comes to the pulmonologist with asthma or bronchitis, and symptoms of chronic obstructive pulmonary disease, your physician's notes may be your best choice.
You should have the right information ready prior to referring to your ICD-9 coding manual to save yourself from trouble. Ensure the documentation supports the physician's diagnosis. After this, be on the lookout for any associated acute conditions. When you face the situation, ask these three important questions that can help you breathe easily through your lung diagnosis coding.
Check whether the patient has status asthmaticus or acute exacerbation before using 493.20
If a pulmonologist diagnosed a patient with both asthma and chronic obstructive pulmonary disease, go to the v493.x section of ICD-9 and choose from the three options: 493.20, 493.21, and 493.22. For some payers, 493.20 is default code. It is always better to check with your pulmonologist first to see if the patient has status asthmaticus or acute exacerbation before settling with 493.20.
Note of caution: A diagnosis of 'status asthmaticus' is the most acute presentation and takes precedence over any type of COPD; as such you should primarily list the most acute diagnosis addressed if the physician documents both findings. On the claim, you should report 493.21, and not 493.22 (an acute exacerbation). If status asthmaticus is documented by the provider with any type of COPD or with acute bronchitis, the status asthmaticus should be sequenced first. It supersedes any type of COPD including that with acute exacerbation or acute bronchitis.
Don't report 466.0 for obstructive chronic bronchitis
When your pulmonologist documents chronic obstructive bronchitis with an episode of acute bronchitis, you should code 491.22. You should not report 466.0 (Acute bronchitis) for the obstructive chronic bronchitis since this code fails to capture the patient complexity of an acute-on-chronic illness, as in 491.22.
Get thorough documentation from your pulmonologist
If you are coding COPD, full details are very important. The documentation should include a listing of signs, symptoms, and conditions. A mere entry of “shortness of breath and cough" may not just be enough. Since cardiopulmonary diseases manifest themselves in this fashion, these symptoms can represent a progression of chronic illness or other acute issues, either related or not related to the patient's chronic disease. As such, clinical evaluation, based on a detailed history, is of prime importance. In order to determine a new illness or a progressing/exacerbating chronic illness, the physician may order blood studies, along with radiographical and physiological evaluations. Just listing COPD as the diagnosis does not reflect the patient's present status. Including the signs, symptoms, or the exacerbation will aid in justifying the medical necessity of the studies ordered. The payer will better understand that these aren't routine surveillance studies.
