Summary & Overview
CPT 1038F: Persistent Asthma Diagnosis, Mild to Severe
CPT code 1038F denotes a diagnosis of persistent asthma—classified as mild, moderate, or severe—and serves as a standardized way to document ongoing asthma in outpatient care. Nationally, accurate coding for persistent asthma matters for clinical tracking, quality measurement, and reporting of chronic respiratory disease burden. It also underpins care management, performance measurement, and payer reporting workflows.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on what the code represents, the typical service context (diagnosis and monitoring in ambulatory settings), and which major payers commonly encounter this code. The publication summarizes relevant benchmarks, clinical context for persistent asthma coding, and where to look for policy or coverage guidance. Data not available in the input is identified where applicable.
This summary is intended for clinicians, coding professionals, and policy analysts seeking a clear national-level overview of CPT code 1038F, its clinical purpose, and payer coverage landscape.
Billing Code Overview
CPT code 1038F indicates a diagnosis of persistent asthma, which may be classified as mild, moderate, or severe. This code documents the presence of ongoing asthma symptoms or persistent disease activity rather than intermittent or resolved asthma.
Service type: Diagnosis of a chronic respiratory condition; evaluation and monitoring related to persistent asthma.
Typical site of service: Outpatient clinic or ambulatory care setting, including primary care and specialty pulmonary or allergy clinics.

Clinical & Coding Specifications
Clinical Context
A typical patient is a school-age child or adult with a history of asthma who presents to a primary care clinic or pulmonary specialty practice for routine follow-up and ongoing management of persistent asthma. The patient reports daily symptoms such as cough, wheeze, shortness of breath with exertion, or nighttime awakenings and uses a controller inhaler regularly. The clinical workflow includes a focused asthma history (symptom frequency, triggers, medication adherence, rescue inhaler use), review of exacerbation history (oral corticosteroid courses, ED visits, hospitalizations), assessment of inhaler technique, peak flow or spirometry if available, and an asthma control assessment to determine severity classification (mild, moderate, or severe persistent). The visit results in documentation of the diagnosis of persistent asthma using code 1038F and an updated management plan, which may include controller therapy adjustments, asthma action plan issuance, counseling on trigger avoidance, and scheduling of follow-up or referral to pulmonology or allergy if control is inadequate.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service | Use when a distinct E/M visit is provided on the same date as a procedure or service related to asthma care (e.g., spirometry). |
26 | Professional component | Use when billing only the professional component of a split service (interpretation of diagnostic tests such as spirometry). |
59 | Distinct procedural service | Use when a separate, unrelated procedure is performed on the same day and must be reported distinctly from asthma-related services. |
57 | Decision for surgery | Uncommon for asthma diagnosis code but used if the visit results in a decision for a surgical procedure related to airway management. |
52 | Reduced services | Use if the asthma-related service or procedure was partially reduced or not completed as documented. |
GA | Waiver of liability statement on file (Medicare) | Use when the patient refuses a recommended service and a signed ABN/waiver is on file. |
GQ | Telehealth via asynchronous telecommunications system | Use when components of asthma assessment are performed via asynchronous telemedicine per payer policy. |
95 | Synchronous telemedicine service rendered via real-time interactive audio and video | Use when the asthma follow-up visit or assessment is delivered via live telehealth. |
TC | Technical component | Use when billing only the technical component of a diagnostic test (e.g., spirometry equipment/time) related to asthma evaluation. |
AE | Principal physician of a limited licensed physician assistant or nurse practitioner service | Use when oversight or principal physician responsibility for services furnished by a delegated mid-level clinician is documented (specific to some payer policies). |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207RP1001X | Pulmonary Disease | Pulmonologists commonly document and manage persistent asthma severity and advanced therapy decisions. |
2084P0202X | Pediatrics | Pediatricians manage persistent asthma in children including diagnosis, controller initiation, and monitoring. |
208D00000X | Family Medicine | Family physicians provide longitudinal asthma care, controller management, and routine follow-up. |
207K00000X | Allergy & Immunology | Allergists evaluate for allergic triggers, immunotherapy considerations, and specialty management of uncontrolled asthma. |
363LP0200X | Respiratory Therapy | Respiratory therapists perform spirometry and inhaler technique education supporting diagnosis and management. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
J45.30 | Mild persistent asthma, uncomplicated | Common subtype of persistent asthma consistent with 1038F diagnosis and management in outpatient settings. |
J45.40 | Moderate persistent asthma, uncomplicated | Represents more frequent symptoms and higher controller therapy needs; aligns with severity captured by 1038F. |
J45.50 | Severe persistent asthma, uncomplicated | Indicates severe disease requiring advanced management; documented under 1038F when present. |
J45.909 | Unspecified asthma, uncomplicated | May be used temporarily when severity not specified; clinically related but less precise than J45.3x–J45.5x. |
Z87.891 | Personal history of nicotine dependence | Relevant as tobacco exposure worsens asthma control and influences counseling and management decisions. |
