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-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 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


These changes became effective October 1, 2021 and all providers of all types should be using the new ICD-10-CM code set now.
