2022 ICD-10-CM Code Z44.9
Encounter for fitting and adjustment of unspecified external prosthetic device
Code Classification
Z44.9 is a billable diagnosis code used to specify a medical diagnosis of encounter for fitting and adjustment of unspecified external prosthetic device. The code Z44.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
The code Z44.9 describes a circumstance which influences the patient's health status but not a current illness or injury. The code is unacceptable as a principal diagnosis.
Unspecified diagnosis codes like Z44.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Code Edits
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:
- Unacceptable principal diagnosis - 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.
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code Z44.9 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
MS-DRG | MS-DRG Title | MCD | Relative Weight |
---|---|---|---|
945 | REHABILITATION WITH CC/MCC | 23 | 1.4847 |
946 | REHABILITATION WITHOUT CC/MCC | 23 | 1.1272 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Present on Admission (POA)
Z44.9 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.
CMS POA Indicator Options and Definitions
POA Indicator Code | POA Reason for Code | CMS will pay the CC/MCC DRG? |
---|---|---|
Y | Diagnosis was present at time of inpatient admission. | YES |
N | Diagnosis was not present at time of inpatient admission. | NO |
U | Documentation insufficient to determine if the condition was present at the time of inpatient admission. | NO |
W | Clinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission. | YES |
1 | Unreported/Not used - Exempt from POA reporting. | NO |
