Is R00.2 a billable ICD-10-CM code?

Yes. R00.2 is a billable, specific ICD-10-CM code and is valid for submission on a claim.

Where does R00.2 sit in the tabular list?

Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R99), in the block Symptoms and signs involving the circulatory and respiratory systems (R00-R09).

What cannot be coded together with R00.2?

R00.2 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above R00.2 (R00) and apply to it just the same.

R00.2

R00.2 — Palpitations

Billable / specific codeICD-10-CM

R00.2 is a billable, specific ICD-10-CM code for palpitations. It is valid for submission on a claim.

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Awareness of heart beat

Excludes1 inherited from the categories above R00.2

These are not written on R00.2, but they bind it: a note on a category applies to every code beneath it. Billing R00.2 with anything listed here is a denial.

Written on R00 — Abnormalities of heart beat

abnormalities originating in the perinatal period (P29.1-)

Excludes2 inherited from the categories above R00.2

Also inherited, and the opposite of Excludes1: these conditions are not part of R00.2, but a patient can have both, so you may code both.

Written on R00 — Abnormalities of heart beat

specified arrhythmias (I47-I49)

Risk adjustment

R00.2 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

R00.2 is named in 24 Medicare coverage policies — 24 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
