Do You Need an SDoH Initiative in Your Medical Coding Program?
Hemant Apte, Chief Executive OfficerSeptember 23, 2023
Social determinants of health (SDoH) are directly impacting medical coding, and more providers should pay attention.
Health.gov defines SDoH as “the conditions in the environments where people are born, live, learn, work, play, worship, and age that affect a wide range of health, functioning, and quality-of-life outcomes and risks” [1]. These include examples like educational level, neighborhood access to safe outdoor spaces, healthcare access, and economic stability. While these conditions are becoming a central aspect of clinical practice, the impact on medical coding has quietly been increasing. Too many providers risk being caught off guard when revenue slides and medical coding audits focus on SDoH.
Back in 2021, CMS issued guidance at the state level to encourage adoption of SDoH strategies. They placed particular emphasis on Medicaid and CHIP programs because of their challenges around access to affordable housing, nutritious food, and meaningful employment opportunities. Z-codes were introduced to improve outcomes by documenting and reporting SDOH data. But fast forward to 2023, and providers haven’t been progressing enough in application to medical coding. A study by the NYU School of Global Public Health found that, even though the codes were being used by over half of the hospitals for housing insecurity, the application essentially stopped there. A second study found that use of Z-codes was more common for Medicaid population patients than the commercial side and that they were most commonly applied in psychiatric or mental health contexts [2]. CMS has issued an infographic and a second similar resource to help encourage use and explain how the codes work [3] [4].
All of CMS’ efforts behind these codes make one thing clear – Z-codes aren’t going away and SDoH will be something the agency will take seriously for years to come. For providers, this means that getting ahead of medical coding audits and updating standards in your medical coding services should include SDoH and Z-codes as a central priority. They might be easy to ignore now, but you don’t want to get caught in the middle of an audit with years of substandard documentation of your patients’ social conditions.
