Infections of skin and subcutaneous tissue-ICD-10 CM GUIDELINES BY BHARATH KUMAR MEDESUN STUDENT

1. INFECTIONS OF THE SKIN AND
SUBCUTANEOUS TISSUE

2. INTRODUCTION
 Skin and soft tissue infections (SSTIs), which
include infections of skin, subcutaneous tissue,
fascia, and muscle, encompass a wide spectrum of
clinical presentations, ranging from simple cellulitis
to rapidly progressive necrotizing fasciitis.
 Diagnosing the exact extent of the disease is
critical for successful management of a patient of
soft tissue infection.

3. CAUSES
 Staphylococcus aureus (the most common
pathogen)
 Streptococcus pyogenes
 Site-specific infections - Indigenous organisms (eg,
gram-negative bacilli in perianal abscesses)
 Immunocompromised hosts and complicated SSTIs
- Multiple organisms or uncommon organisms
(eg, Enterococcus)

4.  Polymicrobial necrotizing fasciitis - Mixed infection
with both aerobes (eg, streptococci, staphylococci,
or aerobic gram-negative bacilli) and anaerobes
(eg, Peptostreptococcus, Bacteroides,
or Clostridium)
 Monomicrobial necrotizing fasciitis: S pyogenes

5. CLASSIFICATION
 Uncomplicated SSTI
 Nonnecrotizing complicated SSTI
 Necrotizing fasciitis

6. DEFINITIONS
 Pyoderma means any skin disease that
is pyogenic (has pus). These include superficial
bacterial infections such as impetigo, impetigo
contagiosa, ecthyma, folliculitis, Bockhart's
impetigo, furuncle, carbuncle, tropical ulcer, etc.

7.  Erythrasma is a skin disease that causes brown,
scaly skin patches. It is caused by the Gram-
positive bacterium
 It is more common among diabetics and the obese,
and in warm climates; it is worsened by wearing
occlusive clothing.

8.  Omphalitis is the medical term for inflammation of
the umbilical cord stump in the neonatal newborn
period, most commonly attributed to a bacterial
infection.

9. ICD-10-CM GUIDELINES
 Use additional code to identify infectious
agent(B95-B97)
 Staphylococcal scalded skin syndromee-L00
 Impetigo-L01
 Cutaneous abscess,furuncle and carbuncle-L02
 Cellulitis and acute lymphangitis-L03

10.  Acute lymphadenitis-L04
 Pilonidal cyst and sinus-L05
 Other local infections of skin and subcutaneous
tissue-L08
