As practitioners dedicated to patient care, it’s important to ensure the financial aspects of your practice are well-managed. 

In specialties such as cardiology, dermatology, and pediatrics, medical billing presents its own set of challenges, with specific requirements for each service rendered. 

Industry statistics indicate that a notable percentage of healthcare revenue is lost due to billing errors and claim denials. This guide aims to clarify the medical billing process for these specialties, providing a straightforward approach to enhance your billing efficiency and financial stability. 

It is created to help you navigate the complexities of medical billing, reduce errors, and maintain a healthy revenue stream for your practice. 

So, without any further delay, let’s get started. 


Billing for cardiology treatment is as complex as the conditions you treat. With procedures that can range from a simple EKG to a full-blown angioplasty, each step, each test, each intervention must be coded with precision.

A single misstep here, and you’re looking at a denial rate that can hit the 15% mark – a direct hit to your revenue stream.

But it’s not just about avoiding missteps; it’s about setting up your billing process to the rhythm of the latest coding updates. Stay in sync, and you’ll keep the lifeblood of your practice flowing.

Common Cardiology CPT Codes:

92950 – Cardio-pulmonary resuscitation (CPR):

Description: This code is used for reporting cardiopulmonary resuscitation services provided in the hospital setting.

93306 – Echocardiography, transthoracic, real-time with image documentation (2D), includes M-mode recording, when performed; complete

Description: This code is used for reporting a comprehensive transthoracic echocardiogram, including real-time 2D imaging and M-mode recording.

93503 – Insertion and placement of flow directed catheter (eg, Swan-Ganz) for monitoring purposes

Description: This code is used for reporting the insertion and placement of a flow-directed catheter, such as a Swan-Ganz catheter, for hemodynamic monitoring.

93610 – Electrophysiologic evaluation of single or dual chamber pacing cardioverter-defibrillator leads, including defibrillation threshold evaluation with induction of arrhythmia

Description: This code is used for reporting the electrophysiologic evaluation of single or dual-chamber pacing cardioverter-defibrillator leads, including defibrillation threshold evaluation.


Dermatology billing might seem straightforward, but it’s layered with complexity. 

Consider this: up to 25% of potential income can vanish due to coding errors, particularly when distinguishing between medical necessity and cosmetic choice. And with the rise of tele dermatology services, which saw a 50% increase during the pandemic, there’s a whole new dimension to billing that requires your attention.

The challenge is to maintain a balance between medical and cosmetic billing – a balance that, if lost, can lead to significant revenue leakage.

Common Dermatology CPT Codes:

11100 – Biopsy of skin, subcutaneous tissue and/or mucous membrane (including simple closure), unless otherwise listed; single lesion

Description: This code is used for reporting the biopsy of a single skin lesion, including simple closure if performed.

17000 – Destruction (eg, laser surgery, electrosurgery, cryosurgery, chemosurgery, surgical curettement), premalignant lesions (eg, actinic keratoses); first lesion

Description: This code is used for reporting the destruction of premalignant lesions, such as actinic keratoses, for the first lesion.

17003 – Each additional lesion

Description: This code is used for reporting the destruction of each additional premalignant lesion beyond the first lesion.

96910 – Photochemotherapy; tar and ultraviolet B (Goeckerman treatment)

Description: This code is used for reporting photochemotherapy using tar and ultraviolet B for conditions such as psoriasis (Goeckerman treatment).


Pediatric billing is like keeping up with kids – it’s always on the move. 

With a 20% chance of missing out on reimbursements for vaccinations due to coding errors, the stakes are high. And it’s not just about getting the codes right; it’s about adapting to the ever-changing immunization schedules and preventive service codes.

The goal? To ensure that your billing practices grow and adapt as quickly as the little ones you’re treating.

Common Pediatrics CPT Codes:

99381 – Initial comprehensive preventive medicine evaluation and management of an infant (age 28 days or younger)

Description: This code is used for reporting the initial comprehensive preventive medicine evaluation and management of an infant.

99392 – Periodic comprehensive preventive medicine reevaluation and management of an individual including an age and gender appropriate history, examination, counseling/anticipatory guidance/risk factor reduction interventions, and the ordering of laboratory/diagnostic procedures, established patient; early childhood (1 through 4 years)

Description: This code is used for reporting periodic comprehensive preventive medicine reevaluation and management for a child in early childhood.

90471 – Immunization administration (includes percutaneous, intradermal, subcutaneous, or intramuscular injections); 1 vaccine (single or combination vaccine/toxoid)

Description: This code is used for reporting the administration of one vaccine, whether it is a single vaccine or a combination vaccine.

96127 – Brief emotional/behavioral assessment (eg, depression inventory, attention-deficit/hyperactivity disorder [ADHD] scale), with scoring and documentation, per standardized instrument

Description: This code is used for reporting a brief emotional/behavioral assessment using a standardized instrument, with scoring and documentation.


Take a step back and consider the medical billing overview of your practice. Are you seeing a healthy stream of revenue, or are there blockages in your cash flow? 

With the industry losing approximately $125 billion due to inefficient billing practices, and providers spending an average of 3.5 hours per week on billing-related tasks, it’s clear that there’s room for improvement.

Accounts Receivable (A/R) and denial management are critical aspects of revenue cycle management for medical practices, including those specializing in Cardiology, Dermatology, and Pediatrics. Here’s a general overview of key considerations for each specialty:
