I49 — Other cardiac arrhythmias
Is I49 billable?
No — I49 is a non-billable header code. I49 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 12 billable codes beneath I49.

Code first
The underlying condition below must be sequenced before I49. I49 describes a manifestation and cannot be the principal or first-listed diagnosis.
Excludes2 — not included here
The conditions below are not part of I49, but a patient may have both at the same time. When documentation supports it, I49 and the excluded code may both be reported.

- 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)
- systemic connective tissue disorders (M30-M36)
- transient cerebral ischemic attacks and related syndromes (G45.-)

How long has I49 existed?
I49 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.
