ICD-10 code F80.2: Mixed Receptive-Expressive Language Disorder
Most speech-language pathology claim denials trace back to a single problem: the wrong code on the right patient. For clinicians treating children or adults with combined language comprehension and production deficits, ICD-10 Code F80.2 is the correct billable code, yet practices routinely submit F80.9 (unspecified) or F80.1 (expressive only), triggering avoidable rejections. This reference covers […]
ICD-10 code E11.69: Type 2 Diabetes with Other Specified Complication
Miscoding type 2 diabetes complications is one of the most common triggers for claim denials in endocrinology and primary care. When a documented complication doesn’t fit the kidney, eye, neurological, circulatory, or skin categories, coders default to E11.9 – and lose both reimbursement accuracy and risk adjustment credit. ICD-10 Code E11.69 exists precisely for these […]
ICD-10 code G30.9: Alzheimer’s Disease, Unspecified
ICD-10 Code G30.9: Definition and Clinical Description Most Alzheimer’s disease claims arrive at the payer with the wrong secondary code, or no secondary code at all. That single documentation gap triggers denials that could be avoided with a clear understanding of ICD-10 Code G30.9 and its mandatory pairing rules. This reference covers everything coders and […]
ICD-10 code M54.9: Dorsalgia, Unspecified – Billing Reference
Back pain is the most commonly coded musculoskeletal diagnosis in the United States, yet it remains one of the most frequently miscoded. Practices submit M54.9 as a reflex code when the documentation actually supports a more specific diagnosis, and payers deny the claim. Or worse, they use it correctly on the first visit but forget […]
ICD-10 code F15.20: Other Stimulant Dependence, Uncomplicated
Stimulant use disorder claims are among the most frequently miscoded diagnoses in behavioral health billing. Coders routinely confuse dependence with abuse, misroute cocaine-related encounters to the F15 category, or select the non-specific parent code F15.2 rather than the billable child code F15.20. Each of these errors creates claim rejections, audit exposure, and delayed reimbursement for […]
ICD-10 code R91.1: Solitary Pulmonary Nodule
ICD-10 Code R91.1: Definition and Clinical Description ICD-10 Code R91.1 identifies a solitary pulmonary nodule, one of the most common incidental findings in chest imaging. Clinically, a solitary pulmonary nodule (SPN) is defined as a single round or oval lesion measuring less than 3 centimeters in diameter, completely surrounded by lung parenchyma and not associated […]
ICD-10 code C80.1: Malignant (Primary) Neoplasm, Unspecified
Unspecified primary malignancy is one of the most audit-sensitive diagnosis categories in oncology coding. Coders face a narrow window: the primary site must genuinely be unidentifiable, not simply undocumented. Using ICD 10 Code C80.1 when more specific site information exists is a leading trigger for claim denials, payer audits, and compliance flags under CMS ICD-10 […]
ICD-10 code G89.18: Other Acute Postprocedural Pain
Postprocedural pain catches a lot of surgical practices off guard at billing time. A patient presents with significant pain in the days following a procedure, the clinician documents it carefully, but the claim comes back denied because the diagnosis code was sequenced incorrectly, or the wrong G89 subcategory was used. Accurate claims management for post-operative […]
ICD-10 code R62.50: Unspecified Developmental Delay in Childhood
When a child is not meeting developmental milestones but the underlying cause remains unclear, clinicians need a precise way to capture that clinical reality in the medical record. Using an incorrect or overly specific code before a diagnosis is confirmed creates audit risk and documentation inconsistencies that payers flag during claim review. ICD 10 Code […]
ICD-10 code F11.20: Opioid Dependence, Uncomplicated
Opioid use disorder billing gets denied more often than almost any other behavioral health claim. A single coding error between F11.10 and F11.20 can trigger an audit, delay payment, or result in a recoupment demand from Medicare or Medicaid. For practices treating patients with opioid dependence, getting ICD 10 Code F11.20 right the first time […]
