ICD-10 Code A52.74 – Syphilis of liver and other viscera (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A52.74 – Syphilis of liver and other viscera
What it is
This code identifies syphilis affecting the liver or other internal organs. Use it when documentation shows visceral involvement from late syphilis, not just a general syphilis diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Reported findings may include hepatic involvement or other organ-specific manifestations attributed to syphilis, supported by the clinician’s diagnosis.
When to use this code
Use A52.74 when the provider specifically documents syphilis of the liver or other viscera. It is appropriate when the record links the infection to internal organ disease, rather than to skin, mucous membrane, or neurologic involvement. Check documentation if the organ site is unclear.
Do not use for
Do not use this code for unspecified syphilis or for non-visceral forms such as primary, secondary, or neurosyphilis. If the note does not confirm hepatic or other visceral involvement, choose a more accurate code.
Coding tip
Code the specific organ involvement only when the provider documents it clearly; otherwise, verify the diagnosis before assigning A52.74.
