2026 ICD-10-CM Diagnosis Code U07Emergency use of U07
U07 is a non-billable ICD-10-CM category code for emergency use of U07, so it cannot be submitted on claims. Use a more specific code from this category instead, such as U07.0 and U07.1.

The Medicare Code Editor (MCE) detects errors and inconsistencies in ICD-10-CM diagnosis coding that can affect Medicare claim validity. These edits help medical coders and billing professionals determine when a diagnosis code is not appropriate as a principal diagnosis or does not meet coverage criteria. Use this list to verify whether a code is valid for Medicare billing and to avoid claim rejections or denials.
Diagnosis-Related Groups classify hospital cases for billing and healthcare management. Patients are grouped by principal diagnosis into Major Diagnostic Categories (MDCs), and once a case is assigned to a DRG the hospital receives a set payment intended to cover the typical cost of treating patients in that group.
The payment depends on the relative weight of the DRG, which reflects the expected complexity and cost of care. Higher weights mean higher reimbursement.
The POA indicator is reported for diagnosis codes on inpatient claims to general acute care hospitals, so CMS can group diagnoses into the proper DRGs. CMS publishes a list of codes that are exempt from POA reporting.
| Indicator | Meaning | CMS pays CC/MCC DRG |
|---|---|---|
| Y | Diagnosis was present at the time of inpatient admission | Yes |
| N | Diagnosis was not present at the time of admission | No |
| U | Documentation is insufficient to determine | No |
| W | Clinically undetermined | Yes |
| 1 | Unreported, exempt from POA reporting | No |
Medicare's Quality Payment Program (QPP) ties reimbursement to quality measures that aim to make patient care more effective, safe, efficient, patient-centered and equitable. When this code is part of a patient's record, the listed measures can apply and affect reimbursement.
The Tabular List of Diseases and Injuries organizes all ICD-10-CM codes head to toe into chapters and sections, with coding notes for inclusions, exclusions, code-first rules and more. The annotations shown here are the ones applicable to this code.
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM codes. These are the index entries that point to this code.
These clinical terms are approximate synonyms, alternative descriptions, or common phrases used by patients, providers, and coders for the same condition. They are useful when searching for a code and the exact medical terminology is unclear.
The Clinical Classifications Software Refined (CCSR), from AHRQ, groups individual ICD-10-CM codes into broader, clinically meaningful categories tied to a body system or specialty. The grouping is widely used for data analysis, reporting and clinical decision support. Each category has a unique CCSR code.
The General Equivalence Mappings are the CMS crosswalk between ICD-10 and legacy ICD-9 codes. They are useful for audits, historical claims and approximate code comparisons. An approximate flag means the match is not exact.
The Table of Neoplasms indexes anatomical sites with six code columns based on the behavior of the neoplasm: malignant primary, malignant secondary, carcinoma in situ, benign, uncertain behavior, or unspecified. The description of the neoplasm usually indicates which column applies; when it does not, the Alphabetic Index provides guidance.
The Table of Drugs and Chemicals classifies drugs, industrial solvents, corrosive gases, noxious plants, pesticides and other toxic agents. Do not code directly from the table; always confirm in the Tabular List. Use as many codes as needed to specify all reported substances, and use each code only once.
