T80.30XA — ABO incompatibility reaction due to transfusion of blood or blood products, unspecified, initial encounter

BillableUnspecifiedCC

Is T80.30XA billable?

Yes, but T80.30XA is an unspecified code. T80.30XA is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, T80.30XA is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting T80.30XA — the more specific alternatives are listed below.

Which MS-DRGs does T80.30XA group to?

T80.30XA sits in MDC 15 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 791Prematurity with Major Problemsmedical

As a secondary diagnosis, T80.30XA is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG. It also carries Hospital-Acquired Condition category 03.

How is T80.30XA listed in the Alphabetic Index?

Inclusion terms

Alternative wording in documentation that is classified to T80.30XA.

  • ABO incompatibility blood transfusion NOS
  • Reaction to ABO incompatibility from transfusion NOS

Excludes1 — never code together — inherited from T80.3

The conditions below can never be reported together with T80.30XA on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • minor blood group antigens reactions (Duffy) (E) (K) (Kell) (Kidd) (Lewis) (M) (N) (P) (S) (T80.A-)

Use additional code — inherited from Chapter 19

Report an additional code alongside T80.30XA to fully describe the condition. T80.30XA is sequenced first.

  • code to identify any retained foreign body, if applicable (Z18.-)

Use additional code — inherited from T80-T88

Report an additional code alongside T80.30XA to fully describe the condition. T80.30XA is sequenced first.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
  • code(s) to identify the specified condition resulting from the complication
  • code to identify devices involved and details of circumstances (Y62-Y82)

Excludes2 — not included here — inherited from Chapter 19

The conditions below are not part of T80.30XA, but a patient may have both at the same time. When documentation supports it, T80.30XA and the excluded code may both be reported.

  • obstetric trauma (O70-O71)

Excludes2 — not included here — inherited from T80-T88

The conditions below are not part of T80.30XA, but a patient may have both at the same time. When documentation supports it, T80.30XA and the excluded code may both be reported.

  • any encounters with medical care for postprocedural conditions in which no complications are present, such as:
  • artificial opening status (Z93.-)

  • specified complications classified elsewhere, such as:
  • cerebrospinal fluid leak from spinal puncture (G97.0)
  • colostomy malfunction (K94.0-)
  • disorders of fluid and electrolyte imbalance (E86-E87)
  • functional disturbances following cardiac surgery (I97.0-I97.1)
  • intraoperative and postprocedural complications of specified body systems (D78.-, E36.-, E89.-, G97.3-, G97.4, H59.3-, H59.-, H95.2-, H95.3, I97.4-, I97.5, J95.6-, J95.7, K91.6-, L76.-, M96.-, N99.-)

  • postsurgical blind-loop syndrome (K91.2)
  • ventilator associated pneumonia (J95.851)

Excludes2 — not included here — inherited from T80

The conditions below are not part of T80.30XA, but a patient may have both at the same time. When documentation supports it, T80.30XA and the excluded code may both be reported.

  • bone marrow transplant rejection (T86.01)
  • febrile nonhemolytic transfusion reaction (R50.84)
  • fluid overload due to transfusion (E87.71)

How long has T80.30XA existed?

T80.30XA has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
