It is important that healthcare providers are aware of these changes so they can prevent payment delays and ensure they are getting paid for their work.

Let´s review some highlights:

Factors influencing health status and contact with health services

There are major updates on Chapter 21 (Z00-Z99 codes). The pandemic has emphasized the importance of this information, that might not be purely medical, but is certainly affecting individual and populations health outcomes.

These ICD-10 changes include 22 new codes on this chapter. 13 of these codes related to housing insecurity, food insecurity and education level.

As the CDC stated, “coding professionals may utilize documentation of social information from social workers, community health workers, case managers, or nurses, if their documentation is included in the official medical record”.

Cough types and cell therapy

The CDC added 6 new codes to identify the different typed of coughs (acute, subacute, chronic, and others). These were added into the R05: Cough hierarchy that defines those characteristics of a cough.

On this section, there were also added 12 codes for complications of immune effector cellular therapy, immune effector cell-associated neurotoxicity syndrome, and a personal history of cellular therapy.

ICD-10 Changes related to COVID-19 Impact

With the still going pandemic, COVID-19 related codes continue to be added to the codes set with two new U codes for Post-COVID condition and Post-COVID condition, unspecified.

In this category, the ICD-10 changes included the new Z code Z71.85 for identifying immunization safety counseling as a reason for an encounter provided on or after October 1st, 2021.

Be sure you check the official code set for note and instruction updates on the codes or procedures that might affect your medical practice.
