Z05.81 is a billable diagnosis code used to specify a medical diagnosis of observation and evaluation of newborn for suspected condition related to home physiologic monitoring device ruled out. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

The code Z05.81 is applicable to newborn patients only. It is clinically and virtually impossible to use this code on a non-newborn patient.

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

  • Encounter for observation of newborn for bradycardia alarm without findings
  • Encounter for observation of newborn for malfunction of home cardiorespiratory monitor
  • Encounter for observation of newborn for non-specific findings home physiologic monitoring device
  • Encounter for observation of newborn for pulse oximeter alarm without findings

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Perinatal / Newborn diagnoses - The Medicare Code Editor detects inconsistencies in perinatal / newborn cases by checking a patient's age and any diagnosis on the patient's record. The newborn code edits apply to patients age 0 years only; a subset of diagnoses which will only occur during the perinatal or newborn period of age 0 (e.g., tetanus neonatorum, health examination for newborn under 8 days old).

Present on Admission (POA)

Z05.81 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.
