CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

T44.7X5S is a billable ICD-10-CM diagnosis code for adverse effect of beta-adrenoreceptor antagonists, sequela. The 7th character S marks it as a sequela code, which reports a problem that remains after the original condition has resolved. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 922 through 923. The code is not accepted as a principal diagnosis by the Medicare Code Editor and exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Poisoning/toxic effect/adverse effects/underdosing, sequela.

Medicare Code Editor checks that affect claim validity for T44.7X5S.

There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Coding GuidelinesGuidance

When coding an adverse effect of a drug that has been correctly prescribed and properly administered, assign the appropriate code for the nature of the adverse effect followed by the appropriate code for the adverse effect of the drug.

The appropriate 7th character is to be added to each code from block Poisoning by, adverse effect of and underdosing of drugs primarily affecting the autonomic nervous system (T44). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Clinical InformationClinical

  • Acebutolol

    a cardioselective beta-1 adrenergic antagonist with little effect on the bronchial receptors. the drug has stabilizing and quinidine-like effects on cardiac rhythm, as well as weak inherent sympathomimetic action.
  • Alprenolol

    one of the adrenergic beta-antagonists used as an antihypertensive, anti-anginal, and anti-arrhythmic agent.
  • Atenolol

    a cardioselective beta-1 adrenergic blocker possessing properties and potency similar to propranolol, but without a negative inotropic effect.
  • Betaxolol

    a cardioselective beta-1-adrenergic antagonist with no partial agonist activity.
  • Bisoprolol

    a cardioselective beta-1 adrenergic blocker. it is effective in the management of hypertension and angina pectoris.
  • Bupranolol

    an adrenergic-beta-2 antagonist that has been used for cardiac arrhythmia, angina pectoris, hypertension, glaucoma, and as an antithrombotic.
  • Carteolol

    a beta-adrenergic antagonist used as an anti-arrhythmia agent, an anti-angina agent, an antihypertensive agent, and an antiglaucoma agent.
  • Celiprolol

    a cardioselective beta-1 adrenergic antagonist that has intrinsic sympathomimetic activity. it is used in the management of angina pectoris and hypertension.
  • Metoprolol

    a selective adrenergic beta-1 blocking agent that is commonly used to treat angina pectoris; hypertension; and cardiac arrhythmias.
  • Nadolol

    a non-selective beta-adrenergic antagonist with a long half-life, used in cardiovascular disease to treat arrhythmias, angina pectoris, and hypertension. nadolol is also used for migraine disorders and for tremor.
  • Oxprenolol

    a beta-adrenergic antagonist used in the treatment of hypertension, angina pectoris, arrhythmias, and anxiety.
  • Penbutolol

    a nonselective beta-blocker used as an antihypertensive and an antianginal agent.
  • Pindolol

    a moderately lipophilic beta blocker (adrenergic beta-antagonists). it is non-cardioselective and has intrinsic sympathomimetic actions, but little membrane-stabilizing activity. (from martindale, the extra pharmocopoeia, 30th ed, p638)
  • Practolol

    a beta-1 adrenergic antagonist that has been used in the emergency treatment of cardiac arrythmias.
  • Propranolol

    a widely used non-cardioselective beta-adrenergic antagonist. propranolol has been used for myocardial infarction; arrhythmia; angina pectoris; hypertension; hyperthyroidism; migraine; pheochromocytoma; and anxiety but adverse effects instigate replacement by newer drugs.
  • Sotalol

    an adrenergic beta-antagonist that is used in the treatment of life-threatening arrhythmias.
  • Timolol

    a beta-adrenergic antagonist that is similar in action to propranolol; the levo-isomer is more active. timolol has been proposed as an anti-hypertensive, anti-arrhythmic, anti-angina, and anti-glaucoma agent. it is also used in the treatment of migraine disorders and tremor.

Questions About T44.7X5SOverview

Is T44.7X5S (Adverse effect of beta-adrenoreceptor antagonists) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report adverse effect of beta-adrenoreceptor antagonists, sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What does the 7th character S in T44.7X5S mean?

The final character S makes this a sequela code: it reports a lingering problem that remains after the adverse effect of beta-adrenoreceptor antagonists itself has resolved, not the original event.

What MS-DRG does T44.7X5S group to?

On inpatient claims, adverse effect of beta-adrenoreceptor antagonists, sequela maps to MS-DRG 922, 923, with relative weights from 1.0177 to 1.7494 depending on complications. Higher weights mean higher Medicare reimbursement.

Can T44.7X5S be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because adverse effect of beta-adrenoreceptor antagonists, sequela describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is T44.7X5S exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for adverse effect of beta-adrenoreceptor antagonists, sequela on inpatient claims.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
