R29.0

R29.0 — Tetany

Billable / specific codeICD-10-CM

R29.0 is a billable, specific ICD-10-CM code for tetany. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

hysterical tetany (F44.5)
neonatal tetany (P71.3)
parathyroid tetany (E20.9)
post-thyroidectomy tetany (E89.2)

Inclusion terms

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

Carpopedal spasm

Other codes that can never be billed with R29.0

These codes carry an Excludes1 note pointing at R29.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R29.0 alone.

E20Hypoparathyroidism

Risk adjustment

R29.0 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

R29.0 is named in 9 Medicare coverage policies — 9 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
