A new ICD-10 Clinical Modification (ICD-10-CM) code set took effect on October 1, 2021. There are some changes to codes that may relate to wound care. As a reminder, if a pathology played a role in the encounter and this is reflected in the documentation, it is likely appropriate to include the ICD-10-CM code that represents that pathology on the claim form.
COVID
COVID-19 may play a role in a wound care encounter. If that occurs, these new codes may need to be considered.
New Codes:
- U09.9 Post COVID-19 condition, unspecified
- Z20.822 Contact with and (suspected) exposure to COVID-19
- Z86.16 Personal history of COVID-19
Thrombocytosis
Thrombocytosis occurs when a patient has a high platelet concentration. This may play a role in wound care and/or surgical planning.
New Codes:
- D75.838 Other thrombocytosis
- D75.839 Thrombocytosis, unspecified
Sjogren’s Syndrome
Sjogren’s syndrome is an autoimmune disease that can have dermatologic manifestations. Until now, the descriptor for the most appropriate ICD-10-CM code to use for Sjogren’s syndrome was, “Sicca syndrome [Sjogren].” However, with this new code set, the descriptor for all M35.0- codes changes from “Sicca syndrome” to “Sjogren syndrome.” With that change, the following code revisions are in the new ICD-10-CM code set:
- Old: M35.00 Sicca syndrome, unspecified
- New: M35.00 Sjögren syndrome, unspecified
- Old: M35.01 Sicca syndrome with keratoconjunctivitis
- New: M35.01 Sjögren syndrome with keratoconjunctivitis
- Old: M35.02 Sicca syndrome with lung involvement
- New: M35.02 Sjögren syndrome with lung involvement
- Old: M35.03 Sicca syndrome with myopathy
- New: M35.03 Sjögren syndrome with myopathy
- Old: M35.04 Sicca syndrome with tubulo-interstitial nephropathy
- New: M35.04 Sjögren syndrome with tubulo-interstitial nephropathy
- Old: M35.09 Sicca syndrome with other organ involvement
- New: M35.09 Sjögren syndrome with other organ involvement
In addition to those changes to the M35.0- codes, these new codes are added:
New codes:
- M35.05 Sjögren syndrome with inflammatory arthritis
- M35.06 Sjögren syndrome with peripheral nervous system involvement
- M35.07 Sjögren syndrome with central nervous system involvement
- M35.08 Sjögren syndrome with gastrointestinal involvement
- M35.0A Sjögren syndrome with glomerular disease
- M35.0B Sjögren syndrome with vasculitis
- M35.0C Sjögren syndrome with dental involvement
Conclusion
These changes became effective October 1, 2021 and all providers of all types should be using the new ICD-10-CM code set now.
