2027 ICD-10-CM Diagnosis Code P72.2Other transitory neonatal disorders of thyroid function, not elsewhere classified
ICD-10-CM Codes›P00–P96›P70-P74›P72
- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
P72.2 is a billable ICD-10-CM diagnosis code for other transitory neonatal disorders of thyroid function, not elsewhere classified. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 794. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 28 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified and unspecified perinatal conditions.

Thyroid Diseases
Your thyroid is a small, butterfly-shaped gland in the front of your neck. It makes hormones that control the way the body uses energy. These hormones affect nearly every organ in your body and control many of your body's most important functions. For example, they affect your breathing, heart rate, weight, digestion, and moods.

Questions About P72.2Overview
Is P72.2 (Other transitory neonatal endocrine disorders) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other transitory neonatal disorders of thyroid function, not elsewhere classified on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does P72.2 group to?
When other transitory neonatal disorders of thyroid function, not elsewhere classified is the principal diagnosis on an inpatient stay, it groups to MS-DRG 794 (neonate with Other Significant Problems), which carries a relative weight of 1.4934. Higher weights mean higher Medicare reimbursement.
Is P72.2 a CC or MCC?
CMS lists P72.2 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 28 closely related codes in its exclusion list.
Can P72.2 be reported with E07.1?
Not as a rule. The Excludes1 note at P72, which applies to P72.2, lists "dyshormogenetic goiter (E07.1)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What is the ICD-9 equivalent of P72.2?
Under the General Equivalence Mappings, other transitory neonatal disorders of thyroid function, not elsewhere classified converts to ICD-9-CM 775.89 (neonat endo/met dis NEC). The mapping is approximate, so confirm the match fits the documentation.
