K05.0 — Acute gingivitis
Is K05.0 billable?
No — K05.0 is a non-billable header code. K05.0 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 2 billable codes beneath K05.0.

Excludes1 — never code together
The conditions below can never be reported together with K05.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from K05
Report an additional code alongside K05.0 to fully describe the condition. K05.0 is sequenced first.
- code to identify:
- alcohol abuse and dependence (F10.-)
- exposure to environmental tobacco smoke (Z77.22)
- exposure to tobacco smoke in the perinatal period (P96.81)
- history of tobacco dependence (Z87.891)
- occupational exposure to environmental tobacco smoke (Z57.31)
- tobacco dependence (F17.-)
- tobacco use (Z72.0)
Excludes2 — not included here — inherited from Chapter 11
The conditions below are not part of K05.0, but a patient may have both at the same time. When documentation supports it, K05.0 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
What codes fall under K05.0? (2)
How long has K05.0 existed?
K05.0 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with K05.0?
ICD-10-CM declares these codes mutually exclusive with K05.0 — exactly one of each pair can be correct for a given encounter.
