ICD-10-CM Code A52.03
Syphilitic endocarditis

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

A52.03 is a billable ICD code used to specify a diagnosis of syphilitic endocarditis. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code A52 is used to code Syphilis

Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. The signs and symptoms of syphilis vary depending in which of the four stages it presents (primary, secondary, latent, and tertiary). The primary stage classically presents with a single chancre (a firm, painless, non-itchy skin ulceration) but there may be multiple sores. In secondary syphilis a diffuse rash which frequently involves the palms of the hands and soles of the feet occurs. There may also be sores in the mouth or vagina. In latent syphilis there are little to no symptoms which can last for years. In tertiary syphilis there are gummas (soft non-cancerous growths), neurological, or heart symptoms. Syphilis has, however, been known as "the great imitator" as it may cause symptoms similar to many other diseases.

MS-DRG Mapping

  • DRG Group #288-290 - Acute and subacute endocarditis with MCC.
  • DRG Group #288-290 - Acute and subacute endocarditis with CC.
  • DRG Group #288-290 - Acute and subacute endocarditis without CC or MCC.

Syphilitic endocarditis of aortic valve (approximate match)
Syphilitic endocarditis of tricuspid valve (approximate match)

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code A52.03 and a single ICD9 code, 093.24 is an approximate match for comparison and conversion purposes.
