🧬 ICD-10 CM D69.9 — Hemorrhagic Condition, Unspecified
Billable Code Confirmed
ICD-10 CM D69.9 is a valid, fully billable 5-character ICD-10-CM code for FY2026, representing the residual unspecified terminus of the D69 category (Purpura and other hemorrhagic conditions). It is assigned when clinical documentation establishes a hemorrhagic or bleeding disorder but does not provide sufficient specificity to assign a more defined code within the D65-D69 coagulation disorders block. As an unspecified code, D69.9 should be assigned only after full chart review and, when appropriate, CDI query to the provider.
Non-Billable Parent Codes
D69 — Purpura and other hemorrhagic conditions is the 3-character category header and is not a valid reportable code; it requires a 4th or 5th character for submission on any claim. D69.4 — Other primary thrombocytopenia is a 4-character non-billable subcategory that requires a 5th character (D69.41, D69.42, or D69.49) before it can be billed; submitting D69.4 alone will result in claim rejection. D69.5 — Secondary thrombocytopenia is similarly non-billable at 4 characters and must be expanded to D69.51 or D69.59 before reporting.
Clinical Context
ICD-10 CM D69.9 is assigned when a provider documents a hemorrhagic or bleeding disorder and the clinical record does not support a more specific code within the D65-D69 block even after review of lab data, hematology consult notes, and prior records. The unspecified designation is appropriate only as a temporary or working code; CDI review should prioritize query to clarify etiology — thrombocytopenia, vascular defect, coagulation factor deficiency — before the patient is discharged. In urology, ophthalmology, and OTO inpatient settings, D69.9 most commonly appears as a secondary comorbidity complicating a primary surgical or procedural encounter.
Code Classification
ICD-10 CM D69.9 is an ICD-10-CM diagnosis code within Chapter 3 (D50-D89), Diseases of the Blood and Blood-Forming Organs and Certain Disorders Involving the Immune Mechanism; it is not a procedural code and has no ICD-10-PCS equivalent. Procedures performed in the setting of this diagnosis — such as blood product transfusion or bone marrow biopsy — are coded separately using ICD-10-PCS. This code classifies to the medical partition of MDC 16 and does not trigger a surgical DRG on its own.
🔍 Code Description
ICD-10 CM D69.9 — Hemorrhagic condition, unspecified — is assigned to inpatient encounters where clinical documentation establishes the presence of an abnormal bleeding or hemorrhagic tendency without sufficient specificity to assign a more defined code within the D65-D69 coagulation disorders block.¹ The D69 category spans a broad range of hemorrhagic pathophysiology including allergic purpura, qualitative platelet defects, thrombocytopenic and nonthrombocytopenic purpura, and other specified conditions, making D69.9 the terminal residual code when those distinctions cannot be drawn from the medical record.² Hemorrhagic conditions in this category may arise from vascular abnormalities, platelet dysfunction, or coagulation factor deficiencies, though by definition the unspecified code does not distinguish between these mechanisms — making CDI query essential when lab or clinical data points to a specific etiology such as D69.3, D68.0, or **D65.**³
In the inpatient setting, D69.9 frequently appears as a secondary diagnosis reflecting a comorbid bleeding diathesis, perioperative hemorrhagic risk, or pre-existing condition influencing the course of treatment.⁴ Urologic, ophthalmologic, and OTO surgical encounters may involve D69.9 when preoperative hematologic evaluation identifies bleeding abnormalities not yet further characterized — for example, an elevated bleeding time or abnormal coagulation panel without confirmed etiology prior to scheduled surgery.⁵ Because D69.9 carries CC weight in many MS-DRG groupings when used as a secondary diagnosis, accurate documentation and capture of the hemorrhagic condition — even when unspecified — can impact facility reimbursement and severity of illness profiling.⁶

Why D69.9 Differs from D69.6 — Thrombocytopenia, Unspecified
ICD-10 CM D69.9 is broader than D69.6 and does not imply a platelet-count deficit; it covers any bleeding disorder without identified mechanism, whereas D69.6 is specifically reserved for confirmed low platelet count without known etiology. If lab data confirms thrombocytopenia but the underlying cause is undetermined, D69.6 is the correct code — assigning D69.9 in that scenario constitutes undercoding and may generate audit flags or payer denials.
Tip
ICD-10 CM D69.9 functions as a CC when used as a secondary diagnosis in many MS-DRG groupings, meaning accurate documentation and capture of this code can influence DRG assignment and facility payment. Avoid assigning D69.9 when the record supports a more specific hemorrhagic code — the unspecified designation should only be used when clinical documentation genuinely does not support greater specificity after full chart review.
✅ Includes
ICD-10 CM D69.9 includes documented hemorrhagic conditions recorded only as NOS (not otherwise specified) when review of the full medical record — including labs, hematology consult notes, and prior records — does not yield sufficient clinical detail to assign a more specific code within the D65-D69 block. It also encompasses bleeding disorders documented solely as “hemorrhagic condition” or “abnormal bleeding tendency” without further elaboration, even after provider query, when the record does not support a defined etiology. Coders must distinguish D69.9 from D65 (disseminated intravascular coagulation/MCC), D68.9 (coagulation defect, unspecified/CC), and D69.6 (thrombocytopenia, unspecified/CC), each of which carries its own specificity level and CC/MCC designation.
❌ Excludes
Excludes 1
ICD-10 CM D69.9 does not carry code-level Excludes 1 notes in FY2026 ICD-10-CM; however, the D69 parent category carries mutually exclusive conditions that govern D69.9 by inheritance.
D65 — Disseminated Intravascular Coagulation (Purpura Fulminans): DIC is classified separately under D65 because it involves a systemic coagulopathy with simultaneous pathologic thrombosis and hemorrhage driven by a distinct pathophysiologic mechanism, and it is an MCC. DIC must never be coded as or with D69.9 for the same condition — even when provider documentation is vague, query is required before assigning D69.9 in the presence of clinical DIC indicators. Sequencing D69.9 in place of D65 results in MCC loss and significant DRG weight reduction with RAC audit exposure.
M31.1 — Thrombotic Thrombocytopenic Purpura (TTP): TTP is classified under Diseases of the Musculoskeletal System and cannot be coded simultaneously with D69.9 for the same hemorrhagic condition. TTP involves a distinct ADAMTS13 enzyme deficiency mechanism managed with plasma exchange — a specificity level incompatible with the unspecified D69.9 designation. Assigning D69.9 when TTP is documented is a significant coding error with payer audit and recoupment risk.
Danger
The most common Excludes 1 error with D69.9 is assigning it when the record documents DIC (D65) or TTP (M31.1). Both conditions are more specific, carry greater CC/MCC weight, and are mutually exclusive with D69.9 by ICD-10-CM convention at the D69 category level. These errors are frequently identified in RAC, MAC, and internal audits and result in recoupment or claim denial.
Excludes 2
D89.0 — Polyclonal Hypergammaglobulinemia (Benign Hypergammaglobulinemic Purpura): This condition may be coded in addition to D69.9 when both the immunologic disorder and an unrelated unspecified hemorrhagic condition are independently present and documented. Coders should evaluate whether the purpura is directly attributable to the hypergammaglobulinemia — if it is, D89.0 alone is the more precise code and D69.9 would be redundant.
D47.3 — Essential (Hemorrhagic) Thrombocythemia: If a patient has both essential thrombocythemia and a separate, unrelated hemorrhagic condition, both codes may be reported. However, if the hemorrhagic condition is a direct manifestation of the thrombocythemia, only D47.3 should be assigned, as the hemorrhagic tendency is inherent to that diagnosis.
📋 Clinical Overview
Hemorrhagic Conditions: Unspecified vs. Specified
Accurate assignment of D69.9 requires ruling out all more specific hemorrhagic diagnoses within the D65-D69 block and adjacent categories. Clinical features that should trigger a provider query include platelet count trends, coagulation panel abnormalities (PT, PTT, INR, fibrinogen), family history of bleeding disorders, medication history (anticoagulants, antiplatelets), and response to hemostatic interventions.⁷
| Feature | D69.9 | D69.3 | D68.9 |
|---|---|---|---|
| Mechanism | Unknown or unspecified hemorrhagic condition; no mechanism identified in documentation | Immune-mediated platelet destruction (ITP); autoantibody against platelet surface antigens; typically presents with isolated low platelet count and petechiae or mucocutaneous bleeding | Unspecified coagulation factor deficiency or inhibitor not elsewhere classified; covers defects in the intrinsic, extrinsic, or common coagulation pathways |
| Lab Findings | No specific lab pattern required; code is used when documentation lacks lab-linked diagnosis | Low platelet count (<100,000/µL); normal PT and PTT; bone marrow may show increased megakaryocytes; antiplatelet antibody may or may not be detectable | Prolonged PT and/or PTT depending on factor affected; platelet count typically normal; fibrinogen may be affected in common pathway defects |
| CC/MCC Status & DRG Impact | CC when used as secondary diagnosis; no independent MCC/CC contribution as principal; unspecified code limits HCC and DRG optimization | CC when used as secondary diagnosis; preferred over D69.9 when ITP is clinically supported; more specific and defensible in audit | CC when secondary; preferred when coagulation panel is abnormal without platelet involvement; supports CDI query documentation trail |
Important
Any inpatient encounter where D69.9 appears on the problem list warrants a CDI query if clinical indicators — abnormal coagulation labs, active bleeding episodes, hematology consult, or treatment with blood products or hemostatic agents — suggest a more specific diagnosis is supportable. Capturing specificity increases DRG weight accuracy, reduces audit exposure, and supports accurate severity of illness and risk of mortality profiling.
Manifestations & Symptom Burden
Petechiae and ecchymosis: Pinpoint or larger skin hemorrhages appearing spontaneously or with minimal trauma are the most visible clinical signs driving hemorrhagic condition documentation and should prompt lab-based differentiation.⁸
Mucosal bleeding: Epistaxis, gingival bleeding, and gastrointestinal bleeding are common presentations; in OTO patients, epistaxis may co-occur with sinonasal procedures and complicate surgical planning, supporting secondary diagnosis capture.⁹
Hematuria: Unexplained hematuria in urology patients may reflect an underlying hemorrhagic diathesis and should prompt evaluation for coagulation abnormalities before procedural intervention.¹⁰
Intraoperative or postoperative bleeding: Unexpected hemorrhage during or after urologic, ophthalmologic, or OTO procedures may be the presenting event that drives hemorrhagic condition documentation and workup — D69.9 or a more specific code should be captured when this occurs.¹¹
Mucocutaneous bleeding pattern: Systemic mucocutaneous bleeding involving multiple sites helps differentiate a generalized hemorrhagic diathesis from localized surgical bleeding and supports the medical necessity of hematology consultation.¹²
Tip
In inpatient urology, ophthalmology, and OTO coding, D69.9 or its more specific equivalents most often appear as secondary diagnoses complicating a primary surgical or procedural encounter. Document the clinical impact of the hemorrhagic condition on management — delayed surgery, additional blood product orders, hematology consultation, or modified anesthetic planning — to support medical necessity and CC capture.
💰 HCC Risk Adjustment
| Field | Detail |
|---|---|
| HCC Category | N/A — Not HCC-Mapped |
| RAF Score Impact | None — D69.9 does not contribute to risk adjustment score |
| Model Version | CMS-HCC Model v28 (FY2026) |
| Annual Recapture Required | N/A |
| Payer Relevance | Medicare Advantage, Medicaid Managed Care — no HCC credit generated |
ICD-10 CM D69.9 does not map to any HCC category in CMS-HCC Model v28 and therefore generates no RAF score increment for Medicare Advantage or Medicaid managed care risk adjustment.¹³ When a patient’s hemorrhagic condition is more specifically characterized — such as D69.3 (immune thrombocytopenic purpura), D66 (hereditary factor VIII deficiency/hemophilia A), or D67 (hereditary factor IX deficiency/hemophilia B) — those codes may carry HCC weight and should be queried and documented to support accurate risk scoring. Facilities and physicians participating in value-based contracts should prioritize CDI efforts to replace unspecified D69.9 with specific codes that map to HCC categories wherever the clinical record supports specificity. Repeated use of unspecified codes without clinical support may attract payer scrutiny and trigger focused chart review.¹⁴
🏥 MS-DRG Assignment
| DRG | Title | Est. Relative Weight |
|---|---|---|
| DRG 813 | Coagulation Disorders with MCC | ~1.6 (verify CMS IPPS Final Rule) |
| DRG 814 | Coagulation Disorders with CC | ~0.9 (verify CMS IPPS Final Rule) |
| DRG 815 | Coagulation Disorders without CC/MCC | ~0.7 (verify CMS IPPS Final Rule) |
When D69.9 is sequenced as the principal diagnosis, it maps to MDC 16 and the Coagulation Disorders DRG family (813-815), with final assignment determined by CC/MCC status of secondary diagnoses.¹⁵ Because D69.9 is itself an unspecified code, it does not independently carry MCC or CC weight as principal diagnosis — DRG optimization relies entirely on what comorbidities are documented alongside it and their CC/MCC designations.¹⁶ When D69.9 appears as a secondary diagnosis, it functions as a CC and may upgrade the DRG tier of the primary condition’s DRG family — this capture is clinically and financially significant and should not be omitted when the condition is present and documented as affecting management.¹⁷ Coders should always validate DRG weights against the current CMS IPPS Final Rule addenda, as weights are updated annually and the estimates above are for reference only.¹⁸

🛠️ Commonly Associated CPT Codes
85025 — Complete Blood Count (CBC) with Automated Differential: Universally ordered in the workup of any hemorrhagic condition; platelet count, WBC differential, and red cell indices help differentiate thrombocytopenic from non-thrombocytopenic etiologies and inform CDI query direction.¹⁹ In the profee inpatient setting, CBC is reportable once per date of service per ordering physician or qualified professional and should be documented with clinical rationale linking it to the hemorrhagic workup.²⁰
85610 — Prothrombin Time (PT): Core coagulation panel test evaluating the extrinsic and common coagulation pathways; PT elevation may signal factor deficiency, liver dysfunction, or anticoagulant effect.²¹ Abnormal PT in combination with clinical bleeding should trigger a CDI query toward a more specific coagulation defect code — particularly D68.9 — rather than retaining D69.9 as the final diagnosis.²²
85730 — Partial Thromboplastin Time (PTT/APTT): Evaluates the intrinsic coagulation pathway; a normal PT with prolonged PTT is a clinical pattern suggesting factor VIII, IX, XI deficiency, or a lupus anticoagulant.²³ This pattern should prompt provider query toward D66, D67, or D68.0 before D69.9 is finalized.²⁴
36430 — Transfusion of Blood: Whole blood or packed red cell transfusion indicated when hemorrhagic condition causes significant anemia; report per transfusion event with diagnosis linking to the hemorrhagic condition.²⁵ In the inpatient profee setting, transfusion administration should be separately documented with its clinical rationale clearly tied to the active hemorrhagic diagnosis.²⁶
85379 — Fibrin Degradation Products, Quantitative (D-Dimer): Ordered when DIC (D65) is in the differential; markedly elevated D-dimer concurrent with thrombocytopenia and low fibrinogen should immediately trigger CDI query to differentiate D69.9 from D65.²⁷ Failure to capture DIC when clinically supported results in MCC loss and significant DRG weight reduction — this is one of the highest-value CDI query opportunities in the hemorrhagic condition family.²⁸
38222 — Diagnostic Bone Marrow Aspirations and Biopsy(ies): Performed when the etiology of hemorrhagic condition is unclear and marrow pathology — thrombocytopenia of marrow origin, aplastic anemia, hematologic malignancy — is suspected; report with modifier -26 (professional component) if only the interpretation is billable to the physician.²⁹ Results of bone marrow biopsy frequently provide the specificity needed to recode D69.9 to a more definitive diagnosis at or before discharge.³⁰
NCCI Bundling Considerations
CBC (85025) and coagulation panels (85610, 85730) are not bundled with each other and may be reported on the same date of service by the same provider without an NCCI edit conflict. Bone marrow aspiration and biopsy components should be reported using the combination code 38222 rather than separate aspiration and biopsy codes to avoid NCCI edit bundling issues and claim rejection. Transfusion administration (36430) is not bundled with diagnostic lab codes but must be supported by documentation of medical necessity linked to the active hemorrhagic condition.³¹
🔬 ICD-10-PCS Crosswalk
30233N1 — Transfusion of Nonautologous Red Blood Cells into Peripheral Vein, Percutaneous Approach: Assigned when packed RBC transfusion is administered via peripheral IV access in the context of hemorrhagic condition causing clinically significant anemia; the value “N” represents nonautologous red blood cells, and “1” designates the nonautologous qualifier in the 7th character position.³² Documentation must specify peripheral vs. central access, as central venous transfusion uses a different 4th character value and a different PCS code.³³
30243N1 — Transfusion of Nonautologous Red Blood Cells into Central Vein, Percutaneous Approach: Used when blood product administration occurs through a central venous catheter; the “4” in the 4th character position designates the central vein body part versus the peripheral vein in 30233N1.³⁴ Central venous administration is common in critically ill patients with active hemorrhagic conditions who have poor peripheral access or require volume management in conjunction with hemostatic intervention.³⁵
07DT3ZX — Extraction of Bone Marrow, Percutaneous Approach, Diagnostic: Assigned for bone marrow aspiration/biopsy performed to investigate unexplained hemorrhagic condition; the “X” diagnostic qualifier in the 7th character position confirms the procedure is for diagnostic rather than therapeutic purposes.³⁶ Results from this procedure frequently support recoding D69.9 to a more specific hematologic diagnosis — the ICD-10-PCS code should be assigned regardless of whether final diagnosis is changed at discharge.³⁷
30233L1 — Transfusion of Nonautologous Fresh Frozen Plasma into Peripheral Vein, Percutaneous Approach: Used when FFP is transfused to address coagulation factor deficiencies in the context of hemorrhagic condition; the “L” value in the 6th character position identifies fresh frozen plasma as the transfused substance.³⁸ FFP administration in the setting of D69.9 is a strong CDI trigger — the need for plasma transfusion implies a coagulation factor deficiency that may support recoding toward D68.9 or a more specific factor deficiency code.³⁹
💊 Coding Scenarios and Examples
Scenario 1 — Preoperative Hemorrhagic Workup, Urology
A 68-year-old male is admitted for robot-assisted laparoscopic prostatectomy. Preoperative labs reveal a prolonged bleeding time and elevated PTT with no clear etiology after CBC, PT, and PTT review. Hematology is consulted and documents “hemorrhagic condition under evaluation; etiology to be determined.” Surgery is deferred. The provider does not further specify the disorder before discharge.
Correct Codes:
- D69.9 — Hemorrhagic condition, unspecified (principal)
- Secondary comorbidities as documented
Sequencing: D69.9 is principal because the hemorrhagic condition was the primary reason for the encounter and drove admission. The planned surgical procedure was not performed and is not coded. CDI note: Query the provider and hematologist pre-discharge — the prolonged PTT is a clinical indicator that may support D68.9 (coagulation defect, unspecified) or D66 (factor VIII deficiency) pending workup results; do not wait until the discharge summary to initiate query.⁴⁰
Scenario 2 — Secondary Hemorrhagic Condition Complicating OTO Procedure
A 54-year-old female is admitted for functional endoscopic sinus surgery (FESS) for chronic sinusitis. Intraoperatively, unexpected significant bleeding is encountered. Postoperative workup reveals an unspecified underlying hemorrhagic condition. Hematology is consulted; no further specificity is documented in the medical record at discharge.
Correct Codes:
- J32.9 — Chronic sinusitis, unspecified (principal)
- D69.9 — Hemorrhagic condition, unspecified (secondary/CC)
- Applicable intraoperative complication code if separately documented
Sequencing: Chronic sinusitis is principal; D69.9 is a CC comorbidity that impacted the surgical course and postoperative management. D69.9 as a CC may upgrade DRG weight within the primary DRG family. CDI note: Document in the discharge summary the clinical impact of the hemorrhagic condition on surgical management — specifically that it altered intraoperative hemostasis, extended operative time, or drove hematology consultation — to support secondary code capture and medical necessity.⁴¹
Scenario 3 — Comorbid Hemorrhagic Condition, Ophthalmology
A 73-year-old patient with a pre-existing documented hemorrhagic condition (NOS per prior records) is admitted for surgical repair of retinal detachment. The ophthalmologic team documents the hemorrhagic condition and modifies perioperative management accordingly, including modified anticoagulation planning and coordination with hematology.
Correct Codes:
- H33.011 — Retinal detachment with single break, right eye (principal — assign correct laterality per documentation)
- D69.9 — Hemorrhagic condition, unspecified (secondary/CC)
Sequencing: Retinal detachment is principal; D69.9 is the comorbid hemorrhagic condition documented as influencing clinical management. D69.9 as a CC may upgrade the DRG tier within the ophthalmology surgical DRG family. CDI note: If prior records specify the hemorrhagic condition more definitively (e.g., von Willebrand’s disease, ITP), that specificity should be carried forward per ICD-10-CM Official Guidelines Section I — a prior confirmed diagnosis should not be downgraded to D69.9 in the current encounter.⁴²
⚠️ Coding Pitfalls and Tips
1. Never default to D69.9 when a more specific code is supported: Review the full chart — including lab values, hematology consult notes, medication list, and prior records — before finalizing D69.9. Codes such as D69.3 (ITP), D69.6 (thrombocytopenia, unspecified), D68.9 (coagulation defect, unspecified), and D65 (DIC) each represent more specific diagnoses that carry greater DRG, CC/MCC, and HCC value.⁴³
2. D69.9 ≠ DIC — MCC loss risk is high: DIC (D65) is an Excludes 1 condition at the D69 category level and cannot be assigned as or alongside D69.9 for the same condition. D65 is an MCC — misassigning D69.9 in place of DIC strips the MCC designation and may reduce the DRG geometric mean length of stay and reimbursement, creating RAC recoupment exposure.⁴⁴
3. Confirmed low platelet count = D69.6, not D69.9: If lab data confirms thrombocytopenia, assign D69.6 (thrombocytopenia, unspecified) rather than D69.9, which is reserved for hemorrhagic conditions without any identified platelet pathology. Assigning D69.9 when platelet count data supports D69.6 is an undercoding error that misrepresents the clinical diagnosis.⁴⁵
4. D69.9 as secondary CC — do not omit: D69.9 is a CC when used as a secondary diagnosis and should always be captured when present and documented as affecting clinical management. Omitting D69.9 as a secondary code represents a missed opportunity for accurate DRG weight, severity of illness, and risk of mortality documentation.⁴⁶
5. Prior records and continuity of care: Per ICD-10-CM Official Guidelines, diagnoses confirmed in prior records may be used as the basis for inpatient coding in the current encounter. If a patient’s prior records support a more specific hemorrhagic diagnosis, that specificity must be carried forward and must not be downgraded to D69.9 simply because the current provider did not re-specify it in this admission’s notes.⁴⁷
6. Initiate CDI query early, not at discharge: CDI queries about hemorrhagic condition etiology should be initiated early in the inpatient stay when lab results begin to clarify the picture. Early query allows the provider to document specificity based on evolving lab findings and hematology input, producing a more accurate final code assignment — last-minute discharge day queries frequently go unanswered.⁴⁸
