The chapter with the largest update is Chapter 20, with 123 new codes. The expansion in this chapter pertains to foreign bodies, including button batteries, other, plastic objects, glass items, magnetic metal objects, non-magnetic things, rubber bands, food, non-organic items, and sharp objects entering into or through a natural orifice.
The Diseases of Musculoskeletal System chapter has the second-most changes, with 36 additions. Age-related and other osteoporosis with sites of left, right, and unspecified pelvis are the reasons for these changes.
Diseases of the Eye and Adnexa, Chapter 7, has 34 additions and one deletion. The new codes include non-proliferative/proliferative sickle-cell retinopathy, specific eye muscle entrapment, and foreign body sensation. The changes also include laterality.
The fourth-most changes are found in Chapter 21 (Factors Influencing Health Status and Contact with Health Services), with 30 additions and six deletions. As stated before, the deletions are due to expanded diagnosis codes. The new codes include observation of newborn for suspected condition ruled out, carrier of Acinetobacter baumannii bacteria, encounter for prophylactic measures, family history of specific colon polyps, and caregiver’s non-compliance type. The Social Determinants of Health (SDoH) have also been enhanced, with new codes for child custody and parental/adult-child conflict.
The new code topics can be found in the materials for the Coordination and Maintenance Committee meetings of March and September 2022. The presentations, recordings, and meeting materials can be found on the CDC website.
The ICD-10-CM guideline changes were not released with the new codes. That document is a coming attraction. The guideline changes and new code details will be discussed on Aug. 15 in an upcoming webcast.
