Unlisted hematology and coagulation procedure

CPT4 code

Name of the Procedure:

Unlisted Hematology and Coagulation Procedure


This procedure involves specialized, often innovative or experimental, tests and treatments related to blood disorders and clotting issues. It is not classified under standard hematology and coagulation procedures, meaning it may be highly specific to an individual's condition.


It addresses abnormal blood conditions and coagulation disorders that are either rare or not fully understood. The goal is to diagnose, monitor, or treat such conditions in a tailored manner.


  • Disorders like rare anemias, unusual bleeding disorders, or undiagnosed clotting issues.
  • Conditions that do not respond to standard hematology and coagulation tests or treatments.
  • Patients with unique medical histories that complicate standard diagnostic or treatment approaches.


  • Detailed medical history review and previous test results.
  • Specific instructions might include fasting or temporary cessation of certain medications.
  • Pre-procedure tests may include complete blood count (CBC), coagulation profile, and others as specified by the healthcare provider.

Procedure Description

  1. The patient may undergo a variety of tests that could include specialized blood draws, bone marrow biopsies, or genetic testing.
  2. Advanced laboratory techniques and equipment are used to analyze samples.
  3. If a treatment is involved, it may include medication administration, transfusions, or other advanced therapies.
  4. Procedures may be performed under local anesthesia or sedation, depending on the complexity.


The duration varies; diagnostic tests may take a few hours, while some treatments could span multiple sessions over days or weeks.


Most tests and treatments occur in specialized hospital departments, outpatient clinics, or diagnostic laboratories equipped for advanced hematological studies.


  • Hematologists
  • Specialist nurses
  • Laboratory technicians
  • Anesthesiologists (if sedation is required)

Risks and Complications

  • Common risks: discomfort or bruising at the sample collection site, mild bleeding.
  • Rare risks: infection, significant bleeding, adverse reactions to sedatives or contrast materials.
  • Management includes prompt medical intervention tailored to the specific complication.


  • Precise diagnosis or tailored treatment plan for complex or rare blood disorders.
  • Improvement in symptoms and a better understanding of the condition’s nature.
  • Benefits might be realized shortly after results interpretation or treatment initiation.


  • Post-procedure instructions may include rest, hydration, and monitoring for signs of infection.
  • Recovery time varies based on the procedure’s nature and the patient's overall health.
  • Follow-up appointments are often required for further evaluation and treatment adjustment.


  • Standard hematology tests and treatments.
  • Specialized procedures or treatments in related medical fields.
  • The pros include the well-established nature of standard procedures, while cons might be less specificity and effectiveness for unique conditions.

Patient Experience

  • Patients might feel anxious or uncomfortable but should experience minimal pain due to local anesthesia or sedation.
  • Post-procedure, discomfort is usually mild and manageable.
  • Comprehensive patient care includes pain management and support from the healthcare team.
